+ + allow building both shared and static librarys with + -D GEOGRAPHICLIB_LIB_TYPE=BOTH; + + both shared and static libraries (Release plus Debug) included in + binary installer; + + find_package uses COMPONENTS and GeographicLib_USE_STATIC_LIBS to + select the library to use; + + find_package version checking allows nmake and Visual Studio + generators to interoperate on Windows; + + find_package (GeographicLib ...) requires that GeographicLib be + capitalized correctly; + + on Unix/Linux, don't include the version number in directory for + the cmake configuration files; + + defaults for GEOGRAPHICLIB_DOCUMENTATION and + BUILD_NETGEOGRAPHICLIB are now OFF; + + the GEOGRAPHICLIB_EXAMPLES configuration parameter is no longer + used; cmake always configures to build the examples, but they are + not built by default (instead build targets: exampleprograms and + netexamples);

+ +%GeographicLib offers a C++ interfaces to a small (but important!) set +of geographic transformations. It grew out of a desire to improve on +the geotrans +package for transforming between geographic and MGRS coordinates. At +present, %GeographicLib provides UTM, UPS, MGRS, geocentric, and local +cartesian projections, gravity and geomagnetic models, and classes for +geodesic calculations. + +The goals of %GeographicLib are: + - Accuracy. In most applications the accuracy is close to round-off, + about 5 nm (5 nanometers). Even though in many geographic + applications 1 cm is considered "accurate enough", there is little + penalty in providing much better accuracy. In situations where a + faster approximate algorithm is necessary, %GeographicLib offers an + accurate benchmark to guide the development. + - Completeness. For each of the projections included, an attempt is + made to provide a complete solution. For example, + GeographicLib::Geodesic::Inverse works for anti-podal points. + Similarly, GeographicLib::Geocentric.Reverse will return accurate + geodetic coordinates even for points close to the center of the + earth. + - C++ interface. For the projection methods, this allows encapsulation + of the ellipsoid parameters. + - Emphasis on projections necessary for analyzing military data. + - Uniform treatment of UTM/UPS. The GeographicLib::UTMUPS class treats + UPS as zone 0. This simplifies conversions between UTM and UPS + coordinates, etc. + - Well defined and stable conventions for the conversion between + UTM/UPS to MGRS coordinates. + - Detailed internal documentation on the algorithms. For the most part + %GeographicLib uses published algorithms and references are given. If + changes have been made (usually to improve the numerical accuracy), + these are described in the code. + +Various \ref utilities are provided with the library. These illustrate +the use of the library and are useful in their own right. This library +and the utilities have been tested with g++ 4.4 under Linux, with g++ +4.2 under Mac OS X, and with MS Visual Studio 9 (2008), 10 (2010), 11 +(2012), and 12 (2013) compiled for 32 bit and 64 bit. + +Matlab, JavaScript, and Python interfaces are provided to portions of +%GeographicLib; see \ref other. + +The section \ref geodesic documents the method of solving the geodesic +problem. + +The section \ref transversemercator documents various properties of this +projection. + +The bulk of the testing has used geographically relevant values of the +flattening. Thus, you can expect close to full accuracy for -0.01 ≤ +\e f ≤ 0.01 (but note that GeographicLib::TransverseMercatorExact is +restricted to \e f > 0). However, reasonably accurate results can be +expected if -0.1 ≤ \e f ≤ 0.1. Outside this range, you should +attempt to verify the accuracy of the routines independently. Two types +of problems may occur with larger values of \e f: + - Some classes, specifically GeographicLib::Geodesic, + GeographicLib::GeodesicLine, and GeographicLib::TransverseMercator, + use series expansions using \e f as a small parameter. The accuracy + of these routines will degrade as \e f becomes large. + - Even when exact formulas are used, many of the classes need to invert + the exact formulas (e.g., to invert a projection), typically, using + Newton's method. This usually provides an essentially exact + inversion. However, the choice of starting guess and the exit + conditions have been tuned to cover small values of \e f and the + inversion may be incorrect if \e f is large. + +Undoubtedly, bugs lurk in this code and in the documentation. Please +report any you find to charles@karney.com. + +

+**********************************************************************/ +/** +\page install Installing %GeographicLib + +
+Back to \ref intro. Forward to \ref start. Up to \ref contents. +
+ +%GeographicLib has been developed under Linux with the g++ compiler +(versions 4.0 and later) and under Windows with Visual Studio 2005, 2008, +and 2010. Earlier versions were tested also under Darwin and Solaris. It +should compile on a wide range of other systems. First download either + +GeographicLib-1.34.tar.gz or + +GeographicLib-1.34.zip (or + +GeographicLib-1.34-win32.exe or + +GeographicLib-1.34-win64.exe for binary installation under Windows). +Then pick one of the first five options below: +- \ref cmake. This is the preferred installation method as it will work + on the widest range of platforms. However it requires that you have + cmake installed. +- \ref autoconf. This method works for most Unix-like systems, + including Linux and Mac OS X. +- \ref gnu. This is a simple installation method that works with g++ + and GNU make on Linux and many Unix platforms. +- \ref windows. This is a simple installation method that works with + Visual Studio 2005, 2008, and 2010 under Windows. +- \ref windowsbin. Use this installation method if you only need to use + the \ref utilities supplied with %GeographicLib. (This method also + installs the header files and the library for use by Visual Studio 10.) +- \ref qt. How to compile %GeographicLib so that it can be used by Qt + programs. +- \ref maintainer. This describes addition tasks of interest only to + the maintainers of this code. +. +This section documents only how to install the software. If you +wish to use %GeographicLib to evaluate geoid heights or the earth's +gravitational or magnetic fields, then you must also install the +relevant data files. See \ref geoidinst, \ref gravityinst, and \ref +magneticinst for instructions. + +The first two installation methods use two important techniques which +make software maintanence simpler +- Out-of-source builds: This means that you create a separate + directory for compiling the code. In the description here the + directories are called BUILD and are located in the top-level of the + source tree. You might want to use a suffix to denote the type of + build, e.g., BUILD-vc9 for Visual Studio 9, or BUILD-shared for a + build which creates a shared library. The advantages of out-of-source + builds are: + - You don't mess up the source tree, so it's easy to "clean up". + Indeed the source tree might be on a read-only file system. + - Builds for multiple platforms or compilers don't interfere with each + other. +- The library is installed: After compilation, there is a + separate install step which copies the headers, libraries, + tools, and documentation to a "central" location. You may at this + point delete the source and build directories. If you have + administrative privileges, you can install %GeographicLib for the use + of all users (e.g., in /usr/local). Otherwise, you can install it for + your personal use (e.g., in $HOME/packages). + +\section cmake Installation with cmake + +This is the recommended method of installation; however it requires that +cmake be installed on your system. +This permits %GeographicLib to be built either as a shared or a static +library on a wide variety of systems. cmake can also determine the +capabilities of your system and adjust the compilation of the +libraries and examples appropriately. + +cmake is available for most computer platforms. On Linux systems cmake +will typically one of the standard packages and can be installed by a +command like + \verbatim + yum install cmake \endverbatim +(executed as root). The minimum version of cmake supported for building +%GeographicLib is 2.8.4 (which was released on 2011-02-16). (Actually, +a few earlier versions will also work for non-Windows platforms.) + +On other systems, download a binary installer from http://www.cmake.org +click on download, and save and run the appropriate installer. Run the +cmake command with no arguments to get help. Other useful tools are +ccmake and cmake-gui which offer curses and graphical interfaces to +cmake. Building under cmake depends on whether it is targeting an IDE +(interactive development environment) or generating Unix-style +makefiles. The instructions below have been tested with makefiles and +g++ on Linux and with the Visual Studio IDE on Windows. + +Here are the steps to compile and install %GeographicLib: +- Unpack the source, running one of \verbatim + tar xfpz GeographicLib-1.34.tar.gz + unzip -q GeographicLib-1.34.zip \endverbatim + then enter the directory created with one of \verbatim + cd GeographicLib-1.34 \endverbatim +- Create a separate build directory and enter it, for example, \verbatim + mkdir BUILD + cd BUILD \endverbatim +- Run cmake, pointing it to the source directory (..). On Linux, Unix, + and MacOSX systems, the command is \verbatim + cmake .. \endverbatim + For Windows, the command is typically one of \verbatim + cmake -G "Visual Studio 10" -D CMAKE_INSTALL_PREFIX=C:/pkg-vc10/GeographicLib-1.34 .. + cmake -G "Visual Studio 9 2008" -D CMAKE_INSTALL_PREFIX=C:/pkg-vc9/GeographicLib-1.34 .. +\endverbatim + The definitions of CMAKE_INSTALL_PREFIX are optional (see below). The + settings given above are recommended to ensure that packages that use + %GeographicLib use the version compiled with the right compiler. + If you need to rerun cmake, use \verbatim + cmake . \endverbatim + possibly including some options via -D (see the next step). +- cmake allows you to configure how %GeographicLib is built and installed by + supplying options, for example \verbatim + cmake -D CMAKE_INSTALL_PREFIX=/tmp/geographic . \endverbatim + The options you might need to change are + - COMMON_INSTALL_PATH governs the installation + convention. If it is on ON (the Linux default), the installation + is to a common directory, e.g., /usr/local. If it is OFF (the + Windows default), the installation directory contains the package + name, e.g., C:/pkg/GeographicLib-1.34. The installation + directories for the documentation, cmake configuration, python and + matlab interfaces all depend on the variable with deeper paths + relative to CMAKE_INSTALL_PREFIX being used when it's ON: + - documentation: OFF: doc/html; ON: share/doc/GeographicLib/html; + - cmake configuration: OFF cmake; ON: share/cmake/GeographicLib; + - python interface: OFF: python; ON: lib/python/site-packages; + - matlab interface: OFF: matlab; ON: libexec/GeographicLib/matlab; + . + - CMAKE_INSTALL_PREFIX (default: /usr/local + on non-Windows systems, C:/Program Files/GeographicLib + on Windows systems) specifies where the library will be installed. + For windows systems, it is recommended to use a prefix which + includes the compiler version, as shown above (and also, possibly, + whether this is a 64-bit build, e.g., cmake -G "Visual Studio + 10 Win64" -D CMAKE_INSTALL_PREFIX=C:/pkg-vc10-x64/GeographicLib-1.34 + ..). If you just want to try the library to see if it suits + your needs, pick, for example, + CMAKE_INSTALL_PREFIX=/tmp/geographic. + - GEOGRAPHICLIB_DATA (default: + /usr/local/share/GeographicLib for non-Windows systems, + C:/Documents and Settings/All Users/Application + Data/GeographicLib for Windows systems) specifies the default + location for the various datasets for use by GeographicLib::Geoid, + GeographicLib::GravityModel, and GeographicLib::MagneticModel. + See \ref geoidinst, \ref gravityinst, and \ref magneticinst for more + information. + - GEOGRAPHICLIB_LIB_TYPE (allowed values: SHARED, STATIC, or + BOTH), specifies the types of libraries build. The default is + STATIC for Windows and SHARED otherwise. If building %GeographicLib + for sytem-wide use, BOTH is recommended, because this provides users + with the choice of which library to use. + - CMAKE_BUILD_TYPE (default: Release). This + flags only affects non-IDE compile environments (like make + g++). + The default is actually blank, but this is treated as + Release. Choose one of + \verbatim + Debug + Release + RelWithDebInfo + MinSizeRel +\endverbatim + (With IDE compile environments, you get to select the build type in + the IDE.) + - MATLAB_COMPILER (default: OFF). Set this to either + "mex" (for Matlab) or "mkoctfile" (for Octave) to specify the + compiler to use for the Matlab/Octave interface. See \ref matlab + for more information. + - GEOGRAPHICLIB_DOCUMENTATION (default: OFF). If set to + ON, then html documentation is created from the source files, + provided a sufficiently recent version of doxygen can be found. + Otherwise, the html documentation will redirect to the appropriate + version of the online documentation. + - BUILD_NETGEOGRAPHICLIB (default: OFF). If set to ON, + build the managed C++ wrapper library + NETGeographicLib. This only makes + sense for Windows systems. + - GEOGRAPHICLIB_PRECISION specifies the precision to be + used for "real" (i.e., floating point) numbers. 1 means float + (single precision); 2 (the default) means double; 3 means long + double; 4 is reserved for quadruple precision. Nearly all the + testing has been carried out with doubles and that's the + recommended configuration. In particular you should avoid + "installing" the library with a precision different from double. +- Build and install the software. In non-IDE environments, run + \verbatim + make # compile the library and the examples + make test # run some tests + make install # as root, if CMAKE_INSTALL_PREFIX is a system directory +\endverbatim + Possible additional targets are \verbatim + make matlabinterface (only for the Release configuration on Windows) + make dist + make exampleprograms + make netexamples (supported only for Release configuration) \endverbatim + On IDE environments, run your IDE (e.g., Visual Studio), load + GeographicLib.sln, pick the build type (e.g., Release), and select + "Build Solution". If this succeeds, select "RUN_TESTS" to build; + finally, select "INSTALL" to install (RUN_TESTS and INSTALL are in + the CMakePredefinedTargets folder). Alternatively, you run the + Visual Studio compiler from the command line with \verbatim + cmake --build . --config Release --target ALL_BUILD + cmake --build . --config Release --target RUN_TESTS + cmake --build . --config Release --target INSTALL \endverbatim + For maximum flexibility, it's a good idea to build and install both + the Debug and Release versions of the library (in that order). The + installation directories will then contain the release versions of the + tools and both versions (debug and release) of the libraries. + If you use cmake to configure and build your programs, then the right + version of the library (debug vs. release) will automatically be used. +- The headers, library, and utilities are installed in the + include/GeographicLib, lib, and bin directories under + CMAKE_INSTALL_PREFIX. (dll dynamic libraries are + installed in bin.) For documentation, open in a web browser + + PREFIX/share/doc/GeographicLib/html/index.html, if + COMMON_INSTALL_PATH is ON, or + PREFIX/doc/index.html, otherwise. + +\section autoconf Installation using the autoconfigure tools + +The method works on most Unix-like systems including Linux and Mac OS X. +Here are the steps to compile and install %GeographicLib: +- Unpack the source, running \verbatim + tar xfpz GeographicLib-1.34.tar.gz \endverbatim + then enter the directory created \verbatim + cd GeographicLib-1.34 \endverbatim +- Create a separate build directory and enter it, for example, \verbatim + mkdir BUILD + cd BUILD \endverbatim +- Configure the software, specifing the path of the source directory, + with \verbatim + ../configure \endverbatim +- By default %GeographicLib will be installed under /usr/local. + You can change this with, for example \verbatim + ../configure --prefix=/tmp/geographic \endverbatim +- Compile and install the software with \verbatim + make + make install \endverbatim +- The headers, library, and utilities are installed in the + include/GeographicLib, lib, and bin directories under + prefix. This installation method does not compile + the Matlab/Octave interface; however the source for the interface is + installed in libexec/GeographicLib/matlab, see \ref matlab of + instructions on compiling the interface. For documentation, open + + share/doc/GeographicLib/html/index.html in a web browser. + +\section gnu Installation with GNU compiler and Make + +This method requires the standard GNU suite of tools, in particular make +and g++. This builds a static library and the examples. + +Here are the steps to compile and install %GeographicLib: +- Unpack the source, running \verbatim + tar xfpz GeographicLib-1.34.tar.gz \endverbatim + then enter the directory created \verbatim + cd GeographicLib-1.34 \endverbatim +- Edit \verbatim + include/GeographicLib/Config.h \endverbatim + If your C++ compiler does not recognize the long double type + (unlikely), insert \code + #undef HAVE_LONG_DOUBLE \endcode + If your machine using big endian ordering, then insert \code + #define WORDS_BIGENDIAN 1 \endcode +- Build and install the software: \verbatim + make # compile the library and the examples + make install # as root \endverbatim + The installation is in directories under /usr/local. You + can specify a different installation directory with, for example, + \verbatim + make PREFIX=/tmp/geographic install \endverbatim +- The headers, library, and utilities are installed in the + include/GeographicLib, lib, and bin directories under + PREFIX. This installation method does not compile + the Matlab/Octave interface; however the source for the interface is + installed in libexec/GeographicLib/matlab, see \ref matlab of + instructions on compiling the interface. For documentation, open + + share/doc/GeographicLib/html/index.html in a web browser. + +\section windows Installation on Windows + +This method requires Visual Studio 2005, 2008, or 2010. This builds a +static library and the utilities. If you only have Visual Studio 2003, +use cmake to create the necessary solution file, see \ref cmake. (cmake +is needed to build the Matlab interface and to run the tests.) +- Unpack the source, running \verbatim + unzip -q GeographicLib-1.34.zip \endverbatim +- Open GeographicLib-1.34/windows/GeographicLib-vc10.sln in Visual Studio + 2010 (for Visual Studio 2005 and 2008, replace -vc10 by -vc8 or -vc9). +- Pick the build type (e.g., Release), and select "Build Solution". +- The library and the compiled examples are in the windows/Release. +- Copy the library windows/Release/GeographicLib.lib and the + headers in include/GeographicLib somewhere convenient. The + headers should remain in a directory named %GeographicLib. If you + expect to use the Matlab/Octave interface, copy matlab/*.m and + matlab/*.cpp to a directory in your matlab/octave path, see \ref + matlab for instructions on compiling the interface. For documentation, + open + doc/html/index.html in a web + browser. + +The Visual Studio 10 solution also contains projects to build +NETGeographicLib and the C# example project. + +\section windowsbin Using a binary installer for Windows + +Use this method if you only need to use the %GeographicLib utilities. +The header files and static and shared versions of library are also +provided; these can only be used by Visual Studio 2010 (in either +release or debug mode). However, if you plan to use the library, it may +be advisable to build it with the compiler you are using for your own +code using either \ref cmake or \ref windows. + +Download and run + +GeographicLib-1.34-win32.exe or + +GeographicLib-1.34-win64.exe: + - read the MIT/X11 License agreement, + - select whether you want your PATH modified, + - select the installation folder, by default + C:\\pkg-vc10\\GeographicLib-1.34 or C:\\pkg-vc10-x64\\GeographicLib-1.34, + - select the start menu folder, + - and install. + . +(Note that the default installation folder adheres the the convention +given in \ref cmake.) The start menu will now include links to the +documentation for the library and for the utilities (and a link for +uninstalling the library). If you ask for your PATH to be modified, it +will include C:/pkg-vc10/GeographicLib-1.34/bin where the utilities are +installed. The headers and library are installed in the +include/GeographicLib and lib folders. With the 64-bit installer, the +Matlab interface is installed in the matlab folder. Add this to your +path in Matlab to access this interface. The libraries were built using +using Visual Studio 10 in release and debug modes. The utilities were +linked against the release-mode shared library. The Matlab interface +was compiled with Matlab R2013a 64-bit, however it may work with some +other 64-bit versions of Matlab. +NETGeographicLib library dlls (release and +debug) are included with the binary installers; these are linked against +the shared library for %GeographicLib. + +\section qt Building the library for use with Qt + +If Qt is using a standard compiler, then build %GeographicLib with that +same compiler (and optimization flags) as Qt. + +If you are using the mingw compiler on Windows for Qt, then you need to +build %GeographicLib with mingw. You can accomplish this with cmake +under cygwin with, for example, \verbatim + export PATH="`cygpath -m c:/QtSDK/mingw/bin`:$PATH" + mkdir BUILD + cd BUILD + cmake -G "MinGW Makefiles" -D CMAKE_INSTALL_PREFIX=C:/pkg-mingw/GeographicLib .. + mingw32-make + mingw32-make install \endverbatim +If cmake complains that sh mustn't be in your path, invoke cmake with +\verbatim + env PATH="$( echo $PATH | tr : '\n' | + while read d; do test -f "$d/sh.exe" || echo -n "$d:"; done | + sed 's/:$//' )" \ + cmake -G "MinGW Makefiles" -D CMAKE_INSTALL_PREFIX=C:/pkg-mingw/GeographicLib .. +\endverbatim +If cmake is not available, there is a simple project file that compiles +the %GeographicLib library only with the Qt compiler: \verbatim + cd src + qmake GeographicLib.pro # configure the project + make # build the library \endverbatim +The library will be in the src directory (or the src/release or +src/debug directory under Windows). The headers are in +include/GeographicLib. + +\section maintainer Maintainer tasks + +Check the code out of git with \verbatim + git clone -b master git://git.code.sf.net/p/geographiclib/code geographiclib +\endverbatim +Here the "master" branch is checked out. There are three branches in +the git repository: +- master: the main branch for code maintainence. Releases are + tagged on this branch as, e.g., v1.34. +- devel: the development branch; changes made here are merged + into master. +- release: the release branch created by unpacking the source + releases (git is \e not used to merge changes from the other + branches into this branch). This is the \e default branch of the + repository (the branch you get if cloning the repository without + specifying a branch). This differs from the master branch in that + some administrative files are excluded while some intermediate files + are included (in order to aid building on as many platforms as + possible). Releases are tagged on this branch as, e.g., r1.34. +. +The autoconf configuration script and the formatted man pages are not +checked into master branch of the repository. In order to create the +autoconf configuration script, run \verbatim + sh autogen.sh \endverbatim +in the top level directory. Provided you are running on a system with +doxygen, pod2man, and pod2html installed, then you can create the +documentation and the man pages by building the system using cmake or +configure. + +In the case of cmake, you then run \verbatim + make dist \endverbatim +which will copy the man pages from the build directory back into the +source tree and package the resulting source tree for distribution as +\verbatim + GeographicLib-1.34.tar.gz + GeographicLib-1.34.zip \endverbatim +Finally, \verbatim + make package \endverbatim +or building PACKAGE in Visual Studio will create a binary installer for +%GeographicLib. For Windows, this requires in the installation of +NSIS. On Windows, you should +configure %GeographicLib with PACKAGE_DEBUG_LIBS=ON, build both +Release and Debug versions of the library and finally build PACKAGE in +Release mode. This will get the release and debug versions of the +library included in the package. For example, the 64-bit binary +installer is created with \verbatim + cmake -G "Visual Studio 10 Win64" \ + -D GEOGRAPHICLIB_LIB_TYPE=BOTH \ + -D PACKAGE_DEBUG_LIBS=ON \ + -D MATLAB_COMPILER=mex \ + -D BUILD_NETGEOGRAPHICLIB=ON \ + .. + cmake --build . --config Debug --target ALL_BUILD + cmake --build . --config Release --target ALL_BUILD + cmake --build . --config Release --target matlabinterface + cmake --build . --config Release --target PACKAGE \endverbatim + +With configure, run \verbatim + make dist-gzip \endverbatim +which will create the additional files and packages the results ready +for distribution as \verbatim + geographiclib-1.34.tar.gz \endverbatim + +

+ +Much (but not all!) of the useful functionality of %GeographicLib is +available via simple command line utilities. Interfaces to some of them +are available via the web. See \ref utilities for documentation on +these. + +In order to use %GeographicLib from C++ code, you will need to +- Include the header files for the %GeographicLib classes in your code. + E.g., \code + #include \endcode +- Include the GeographicLib:: namespace prefix to the %GeographicLib classes, + or include \code + using namespace GeographicLib; \endcode + in your code. +- Finally compile and link your code. You have two options here. + - Use cmake to build your package. If you are familiar with cmake + this typically will be far the simplest option. + - Set the include paths and linking options "manually". +- Building your code with cmake. In brief, the necessary steps are: + - include in your CMakeLists.txt files \verbatim + find_package (GeographicLib 1.34 REQUIRED) + include_directories (${GeographicLib_INCLUDE_DIRS}) + add_definitions (${GeographicLib_DEFINITIONS}) + add_executable (program source1.cpp source2.cpp) + target_link_libraries (program ${GeographicLib_LIBRARIES}) \endverbatim + (The add_definitions line is only needed for Windows + and can be omitted if you're using cmake version 2.8.11 or later.) + - configure your package, e.g., with \verbatim + mkdir BUILD + cd BUILD + cmake -G "Visual Studio 10" \ + -D CMAKE_PREFIX_PATH=C:/pkg-vc10 \ + -D CMAKE_PREFIX_PATH=C:/pkg-vc10/testgeographic \ + .. \endverbatim + Note that you almost always want to configure and build your code + somewhere other than the source directory (in this case, we use the + BUILD subdirectory). + - build your package. On Linux and MacOS this usually involves just + running make. On Windows, you can load the solution file created by + cmake into Visual Studio; alternatively, you can get cmake to run + build your code with \verbatim + cmake --build . --config Release --target ALL_BUILD \endverbatim + You might also want to install your package (using "make install" or + build the "INSTALL" target with the command above). + . + The most import step is the find_package command. The cmake + documentation describes the locations searched by find_package (the + appropriate rule for %GeographicLib are those for "Config" mode lookups). + In brief, the locations that are searched are (from least specific to + most specific, i.e., in reverse order) are + - under the system paths, i.e., locations such as C:/Program + Files and /usr/local); + - frequently, it's necessary to search within a "package directory" + (or set of directories) for external dependencies; this is given by + a (semicolon separated) list of directories specified by the cmake + variable CMAKE_PREFIX_PATH (illustrated above); + - the package directory for %GeographicLib can be overridden with the + environment variable GeographicLib_DIR (which is the + directory under which %GeographicLib is installed); + - finally, if you need to point to a particular build of %GeographicLib, + define the cmake variable GeographicLib_DIR, which + specifies the directory containing the configuration file + geographiclib-config.cmake (for debugging this be the + top-level build directory, as opposed to installation + directory, for %GeographicLib). + . + Typically, specifying nothing or CMAKE_PREFIX_PATH + suffices. However the two GeographicLib_DIR variables allow + for a specific version to be chosen. On Windows systems (with Visual + Studio), find_package will only find versions of %GeographicLib built with + the right version of the compiler. (If you used a non-cmake method of + installing %GeographicLib, you can try copying cmake/FindGeographicLib.cmake + to somewhere in your CMAKE_MODULE_PATH in order for + find_package to work. However, this method has not been thoroughly + tested.) + + If %GeographicLib is found, then the following cmake variables are set: + - GeographicLib_FOUND = 1 + - GeographicLib_VERSION = 1.34 + - GeographicLib_INCLUDE_DIRS + - GeographicLib_LIBRARIES = one of the following two: + - GeographicLib_SHARED_LIBRARIES = %GeographicLib + - GeographicLib_STATIC_LIBRARIES = GeographicLib_STATIC + - GeographicLib_DEFINITIONS = one of the following two: + - GeographicLib_SHARED_DEFINITIONS = -DGEOGRAPHICLIB_SHARED_LIB=1 + - GeographicLib_STATIC_DEFINITIONS = -DGEOGRAPHICLIB_SHARED_LIB=0 + - GeographicLib_LIBRARY_DIRS + - GeographicLib_BINARY_DIRS + . + Either of GeographicLib_SHARED_LIBRARIES or + GeographicLib_STATIC_LIBRARIES may be empty, if that version + of the library is unavailable. If you require a specific version, + SHARED or STATIC, of the library, add a COMPONENTS clause + to find_package, e.g., + \verbatim + find_package (GeographicLib 1.34 REQUIRED COMPONENTS SHARED) \endverbatim + causes only packages which include the shared library to be found. If + the package includes both versions of the library, then + GeographicLib_LIBRARIES and + GeographicLib_DEFINITIONS are set to the shared versions, + unless you include \verbatim + set (GeographicLib_USE_STATIC_LIBS ON) \endverbatim + before the find_package command. You can check whether + GeographicLib_LIBRARIES refers to the shared or static + library with \verbatim + get_target_property(_LIBTYPE ${GeographicLib_LIBRARIES} TYPE) \endverbatim + which results in _LIBTYPE being set to + SHARED_LIBRARY or STATIC_LIBRARY. + On Windows, cmake takes care of linking to the release or debug + version of the library as appropriate. (This assumes that the Release + and Debug versions of the libraries were built and installed. This is + true for the Windows binary installer for %GeographicLib version 1.34 and + later.) +- Here are the steps to compile and link your code using %GeographicLib + "manually". + - Tell the compiler where to find the header files. With g++ and with + /usr/local specified as the installation directory, + this is accomplished with \verbatim + g++ -c -g -O3 -funroll-loops -I/usr/local/include testprogram.cpp + \endverbatim + With Visual Studio, specify the include directory in the IDE via, + e.g., + \verbatim + C/C++ -> General -> Additional Include Directories = C:\pkg-vc10\GeographicLib\include + \endverbatim + - If using the shared (or static) library with Visual Studio, define + the macro GEOGRAPHICLIB_SHARED_LIB=1 (or + 0), e.g., + \verbatim + C/C++ -> Preprocessor -> Preprocessor Definitions = GEOGRAPHICLIB_SHARED_LIB=1 + \endverbatim + This is only needed for Windows systems when both shared and static + libraries have been installed. (If you configure your package with + cmake, this definition is added automatically.) + - Tell the linker the name, Geographic, and location of the + library. Using g++ as the linker, you would use \verbatim + g++ -g -o testprogram testprogram.o -L/usr/local/lib -lGeographic + \endverbatim + With Visual Studio, you supply this information in the IDE via, + e.g., \verbatim + Linker -> Input -> Additional Dependencies = Geographic-i.lib (for shared library) + Linker -> Input -> Additional Dependencies = Geographic.lib (for static library) + Linker -> General -> Additional Library Directories = C:\pkg-vc10\Geographic\lib + \endverbatim + Note that the library name is Geographic and not + %GeographicLib. For the Debug version of your program on Windows + add "_d" to the library, e.g., Geographic_d-i.lib or + Geographic_d.lib. + - Tell the runtime environment where to find the shared library + (assuming you compiled %Geographic as a shared library). With g++, + this is accomplished by modifying the link line above to read \verbatim + g++ -g -o testprogram testprogram.o -Wl,-rpath=/usr/local/lib \ + -L/usr/local/lib -lGeographic + \endverbatim + (There are two other ways to specify the location of shared libraries + at runtime: (1) define the environment variable + LD_LIBRARY_PATH to be a colon-separated list of + directories to search; (2) as root, specify /usr/local/lib as a + directory searched by ldconfig(8).) On Windows, you need to ensure + that Geographic.dll or Geographic_d.dll is in the same directory as + your executable or else include the directory containing the dll in + your PATH. + +Here is a very simple test code, which uses the GeographicLib::Geodesic +class: +\include example-Geodesic-small.cpp +This example is examples/example-Geodesic-small.cpp. If you +compile, link, and run it according to the instructions above, it should +print out \verbatim + 5551.76 km \endverbatim +Here is a complete CMakeList.txt files you can use to build this test +code using the installed library: \verbatim +project (geodesictest) +cmake_minimum_required (VERSION 2.8.4) + +find_package (GeographicLib 1.34 REQUIRED) + +if (NOT MSVC) + set (CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE) +endif () + +include_directories (${GeographicLib_INCLUDE_DIRS}) +add_definitions (${GeographicLib_DEFINITIONS}) +add_executable (${PROJECT_NAME} example-Geodesic-small.cpp) +target_link_libraries (${PROJECT_NAME} ${GeographicLib_LIBRARIES}) + +if (MSVC) + get_target_property (_LIBTYPE ${GeographicLib_LIBRARIES} TYPE) + if (_LIBTYPE STREQUAL "SHARED_LIBRARY") + # On Windows systems, copy the shared library to build directory + add_custom_command (TARGET ${PROJECT_NAME} POST_BUILD + COMMAND ${CMAKE_COMMAND} -E + copy $ ${CMAKE_CFG_INTDIR} + COMMENT "Copying shared library for GeographicLib") + endif () +endif () \endverbatim + +The next steps are: + - Learn about and run the \ref utilities. + - Read the section, \ref organization, for an overview of the library. + - Browse the Class List for full documentation + on the classes in the library. + - Look at the example code in the examples directory. Each file + provides a very simple standalone example of using one %GeographicLib + class.

+ +Various utility programs are provided with %GeographicLib. These should +be installed in a directory included in your PATH (e.g., +/usr/local/bin). These programs are wrapper programs that invoke +the underlying functionality provided by the library. + +The utilities are + - + GeoConvert: convert geographic coordinates using + GeographicLib::GeoCoords. + - + GeodSolve: perform geodesic calculations using + GeographicLib::Geodesic and GeographicLib::GeodesicLine. + - + Planimeter: compute the area of geodesic polygons using + GeographicLib::PolygonArea. + - + TransverseMercatorProj: convert between geographic + and transverse Mercator.

+ +Here is a brief description of the relationship between the various +components of %GeographicLib. All of these are defined in the +GeographicLib namespace. + +GeographicLib::TransverseMercator, GeographicLib::PolarStereographic, +GeographicLib::LambertConformalConic, and GeographicLib::AlbersEqualArea +provide the basic projections. The constructors for these classes +specify the ellipsoid and the forward and reverse projections are +implemented as const member functions. TransverseMercator uses +Krüger's series which have been extended to sixth order in the +square of the eccentricity. PolarStereographic, LambertConformalConic, +and AlbersEqualArea use the exact formulas for the projections (e.g., +from Snyder). + +GeographicLib::TransverseMercator::UTM and +GeographicLib::PolarStereographic::UPS are const static instantiations +specific for the WGS84 ellipsoid with the UTM and UPS scale factors. +(These do \e not add the standard false eastings or false northings for +UTM and UPS.) Similarly GeographicLib::LambertConformalConic::Mercator +is a const static instantiation of this projection for a WGS84 ellipsoid +and a standard parallel of 0 (which gives the Mercator projection). +GeographicLib::AlbersEqualArea::CylindricalEqualArea, +AzimuthalEqualAreaNorth, and AzimuthalEqualAreaSouth, likewise provide +special cases of the equal area projection. + +GeographicLib::UTMUPS uses TransverseMercator::UTM and +PolarStereographic::UPS to perform the UTM and UPS +projections. The class offers a uniform interface to UTM and UPS by +treating UPS as UTM zone 0. This class stores no internal state and the +forward and reverse projections are provided via static member +functions. The forward projection offers the ability to override the +standard UTM/UPS choice and the UTM zone. + +GeographicLib::MGRS transforms between UTM/UPS coordinates and MGRS. +UPS coordinates are handled as UTM zone 0. This class stores no +internal state and the forward (UTM/UPS to MGRS) and reverse (MGRS to +UTM/UPS) conversions are provided via static member functions. + +GeographicLib::GeoCoords holds a single geographic location which may be +specified as latitude and longitude, UTM or UPS, or MGRS. Member +functions are provided to convert between coordinate systems and to +provide formatted representations of them. +GeoConvert is a simple command line +utility to provide access to the GeoCoords class. + +GeographicLib::TransverseMercatorExact is a drop in replacement for +TransverseMercator which uses the exact formulas, based on elliptic +functions, for the projection as given by Lee. +TransverseMercatorProj is a +simple command line utility to test to the TransverseMercator and +TransverseMercatorExact. + +GeographicLib::Geodesic and GeographicLib::GeodesicLine perform geodesic +calculations. The constructor for GeographicLib::Geodesic specifies the +ellipsoid and the direct and inverse calculations are implemented as +const member functions. GeographicLib::Geocentric::WGS84 is a const +static instantiation of Geodesic specific for the WGS84 ellipsoid. In +order to perform a series of direct geodesic calculations on a single +line, the GeographicLib::GeodesicLine class can be used. This packages +all the information needed to specify a geodesic. A const member +function returns the coordinates a specified distance from the starting +point. GeodSolve is a simple command +line utility to perform geodesic calculations. +GeographicLib::PolygonArea is a class which compute the area of geodesic +polygons using the Geodesic class and Planimeter is a command line utility for +the same purpose. GeographicLib::AzimuthalEquidistant, +GeographicLib::CassiniSoldner, and GeographicLib::Gnomonic are +projections based on the Geodesic class. GeodesicProj is a command line utility to +exercise these projections. + +GeographicLib::GeodesicExact and GeographicLib::GeodesicLineExact are +drop in replacements for GeographicLib::Geodesic and +GeographicLib::GeodesicLine in which the solution is given in terms of +elliptic integrals (computed by GeographicLib::EllipticFunction). +These classes should be used if the absolute value of the flattening +exceeds 0.02. The -E option to GeodSolve +uses these classes. + +GeographicLib::Geocentric and GeographicLib::LocalCartesian convert between +geodetic and geocentric or a local cartesian system. The constructor for +specifies the ellipsoid and the forward and reverse projections are +implemented as const member functions. GeographicLib::Geocentric::WGS84 is a +const static instantiation of Geocentric specific for the WGS84 ellipsoid. +CartConvert is a simple command line +utility to provide access to these classes. + +GeographicLib::Geoid evaluates geoid heights by interpolation. This is +provided by the operator() member function. +GeoidEval is a simple command line +utility to provide access to this class. This class requires +installation of data files for the various geoid models; see \ref +geoidinst for details. + +GeographicLib::Ellipsoid is a class which performs latitude +conversions and returns various properties of the ellipsoid. + +GeographicLib::GravityModel evaluates the earth's gravitational field +using a particular gravity model. Various member functions return the +gravitational field, the gravity disturbance, the gravity anomaly, and +the geoid height Gravity is a simple +command line utility to provide access to this class. If the field +several points on a circle of latitude are sought then use +GeographicLib::GravityModel::Circle to return a +GeographicLib::GravityCircle object whose member functions performs the +calculations efficiently. (This is particularly important for high +degree models such as EGM2008.) These classes requires installation of +data files for the various gravity models; see \ref gravityinst for +details. + +GeographicLib::MagneticModel evaluates the earth's magnetic field using +a particular magnetic model. The field is provided by the operator() +member function. MagneticField is a +simple command line utility to provide access to this class. If the +field several points on a circle of latitude are sought then use +GeographicLib::MagneticModel::Circle to return a +GeographicLib::MagneticCircle object whose operator() member function +performs the calculation efficiently. (This is particularly important +for high degree models such as emm2010.) These classes requires +installation of data files for the various magnetic models; see \ref +magneticinst for details. + +GeographicLib::Constants, GeographicLib::Math, GeographicLib::Utility, +GeographicLib::DMS, are general utility class which are used +internally by the library; in addition GeographicLib::EllipticFunction +is used by GeographicLib::TransverseMercatorExact, +GeographicLib::Ellipsoid, and GeographicLib::GeodesicExact, and +GeographicLib::GeodesicLineExact; GeographicLib::Accumulator is used +by GeographicLib::PolygonArea, and GeographicLib::SphericalEngine, +GeographicLib::CircularEngine, GeographicLib::SphericalHarmonic, +GeographicLib::SphericalHarmonic1, and +GeographicLib::SphericalHarmonic2 facilitate the summation of +spherical harmonic series which is needed by and +GeographicLib::MagneticModel and GeographicLib::MagneticCircle. One +important definition is GeographicLib::Math::real which is the type +used for real numbers. This allows the library to be easily switched +to using floats, doubles, or long doubles. However all the testing +has been with real set to double and the library should be installed +in this way. + +In general, the constructors for the classes in %GeographicLib check +their arguments and throw GeographicLib::GeographicErr exceptions with a +explanatory message if these are illegal. The member functions, e.g., +the projections implemented by TransverseMercator and +PolarStereographic, the solutions to the geodesic problem, etc., +typically do not check their arguments; the calling program +should ensure that the arguments are legitimate. However, the functions +implemented by UTMUPS, MGRS, and GeoCoords do check their arguments and +may throw GeographicLib::GeographicErr exceptions. Similarly Geoid may +throw exceptions on file errors. If a function does throw an exception, +then the function arguments used for return values will not have been +altered. + +%GeographicLib attempts to act sensibly with NaNs. NaNs in constructors +typically throw errors (an exception is GeodesicLine). However, calling +the class functions with NaNs as arguments is not an error; NaNs are +returned as appropriate. "INV" is treated as an invalid zone +designation by UTMUPS. "INVALID" is the corresponding invalid MGRS +string. (Similary "nan" is the equivalent invalid Geohash.) NaNs allow +the projection of polylines which are separated by NaNs; in this format +they can be easily plotted in Matlab. + +A note about portability. For the most part, the code uses standard C++ +and should be able to be deployed on any system with a modern C++ +compiler. System dependencies come into + - GeographicLib::Math -- GeographicLib needs to define functions such + as atanh for systems that lack them. The system dependence will + disappear with the adoption of C++11 because the needed functions are + part of that standard. + - use of long double -- the type is used only for testing. On systems + which lack this data type the cmake and autoconf configuration + methods should detect its absence and omit the code that depends on + it. + - GeographicLib::Geoid, GeographicLib::GravityModel, and + GeographicLib::MagneticModel -- these class uses system-dependent + default paths for looking up the respective datasets. It also relies + on getenv to find the value of the environment variables. + - GeographicLib::Utility::readarray reads numerical data from binary + files. This assumes that floating point numbers are in IEEE format. + It attempts to handled the "endianness" of the target platform using + the WORDS_BIGENDIAN macro (which sets the compile-time constant + GeographicLib::Math::bigendian). + +An attempt is made to maintain backward compatibility with +%GeographicLib (especially at the level of your source code). Sometimes +it's necessary to take actions that depend on what version of +%GeographicLib is being used; for example, you may want to use a new +feature of %GeographicLib, but want your code still to work with older +versions. In that case, you can test the values of the macros +GEOGRAPHICLIB_VERSION_MAJOR, GEOGRAPHICLIB_VERSION_MINOR, and +GEOGRAPHICLIB_VERSION_PATCH; these expand to numbers (and the last one +is usually 0); these macros appeared starting in version 1.34. There's +also a macro GEOGRAPHICLIB_VERSION_STRING which expands to, e.g., +"1.34"; this macro has been defined since version 1.9. + +

+ +Implementations of subsets of %GeographicLib are available in other languages +- \ref c-fortran +- \ref java. +- \ref javascript. +- \ref python. +- \ref matlab. +- \ref maxima. +- \ref dotnet. + +\section c-fortran C and Fortran implementation + +The directories legacy/C and legacy/Fortran +contain implementations of GeographicLib::Geodesic, +GeographicLib::GeodesicLine, and GeographicLib::PolygonArea in C and +Fortran respectively. These are intended for use in old codes written +in these languages and should work any reasonably modern compiler. +These implementations are entirely self-contained and do not depend on +the rest of %GeographicLib. Sample main programs to solve the direct +and inverse geodesic problems and to compute polygonal areas are +provided. + +For documentation, see + - C library for geodesics, + - Fortran library for geodesics. + +\section java Java implementation + +The directory java contains implementations of +GeographicLib::Geodesic, GeographicLib::GeodesicLine, and +GeographicLib::PolygonArea in Java. This implementation is entirely +self-contained and does not depend on the rest of %GeographicLib. +Sample main programs to solve the direct and inverse geodesic problems +and to compute polygonal areas are provided. + +For documentation, see + - Java library for geodesics. + +\section javascript JavaScript implementation + +The directory doc/scripts/GeographicLib contains the classes +- GeographicLib::Math +- GeographicLib::Accumulator +- GeographicLib::Geodesic +- GeographicLib::GeodesicLine +- GeographicLib::PolygonArea +- GeographicLib::DMS +. +translated into JavaScript. See Interface.js for a simple JavaScript +interface to these routines (documented near the top of the file). +Examples of using this interface are +- a geodesic calculator showing + the solution of direct and inverse geodesic problem, finding + intermediate points on a geodesic line, and computing the area of a + geodesic polygon. +- displaying geodesics in Google + Maps which shows the geodesic, the geodesic circle, and various + geodesic envelopes. +. +These examples include a "stripped" version of the JavaScript code, \code + \endcode +which loads faster. + +\section python Python implementation + +A python implementation of the geodesic routines from GeographicLib +are provided in the python/geographiclib directory (which is installed +as PREFIX/lib/python/site-packages/geographiclib, if +COMMON_INSTALL_PATH is ON, and as PREFIX/python/geographiclib, +otherwise). This contains implementations of the classes +- GeographicLib::Math +- GeographicLib::Accumulator +- GeographicLib::Geodesic +- GeographicLib::GeodesicLine +- GeographicLib::PolygonArea +. +You can also download the python interface independent of the rest of +%GeographicLib from +- + http://pypi.python.org/pypi/geographiclib +. +and then unpack the .tar.gz or .zip file. + +You can "install" these routines, so that they are in python's default +path with, for example \verbatim + cd geographiclib-1.16 + python setup.py install +\endverbatim +(this will require root privileges). Or else you can set the path +within python using \code +>>> import sys +>>> sys.path.append("/usr/local/lib/python/site-packages") +\endcode + +An example of using this interface is \code +>>> from geographiclib.geodesic import Geodesic +>>> # The geodesic inverse problem +... Geodesic.WGS84.Inverse(-41.32, 174.81, 40.96, -5.50) +>>> # The geodesic direct problem +...

To use + these, start Matlab or Octave and run one of (for example) \verbatim + addpath /usr/local/libexec/GeographicLib/matlab + addpath 'C:/pkg-vc10-x64/GeographicLib-1.34/libexec/GeographicLib/matlab' + \endverbatim + The available functions are: + - geoddoc: briefly descibe the routines + - geodreckon: solve the direct geodesic problem + - geoddistance: solve the inverse geodesic problem + - geodarea: compute the area of ellipsoidal polygons + . + Use the help function to get documentation, e.g., \code + help geoddistance \endcode + to obtain documentation. These functions are also available as a + standalone package from + + Matlab File Exchange using the link + - + http://www.mathworks.com/matlabcentral/fileexchange/39108 + - Native Matlab implementations of projections which are related to + geodesics. These are + - geodproj: briefly descibe the routines + - eqdazim_fwd, eqdazim_inv: azimuthal equidistant + - cassini_fwd, cassini_inv: Cassini-Soldner + - tranmerc_fwd, tranmerc_inv: transverse Mercator + - gnomonic_fwd, gnomonic_inv: ellipsoidal gnomonic + - utm_fwd, utm_inv: universal transverse Mercator + . + These functions are also available as a package from + + Matlab File Exchange using the link + - + http://www.mathworks.com/matlabcentral/fileexchange/39366 + . + (This requires that the previous package also be installed.) + - Interface code so that some %GeographicLib classes can be accessed + from Matlab or Octave. The rest of this section describes how to + compile and use these interfaces. + +There are two ways of compiling the interface code: (1) using cmake and +(2) invoking the compiler from Matlab. + - Using cmake: Before running cmake, configure MATLAB on + Windows to use the same compiler that you're going to use for compiling + %GeographicLib. For example \verbatim + mex.bat -setup + + Please choose your compiler for building MEX-files: + Would you like mex to locate installed compilers [y]/n? y + Select a compiler: + [1] Microsoft Visual C++ 2012 in C:\Program Files (x86)\Microsoft Visual Studio 11.0 + [2] Microsoft Visual C++ 2010 in C:\Program Files (x86)\Microsoft Visual Studio 10.0 + + [0] None + + Compiler: 2 + etc. \endverbatim + (This will require that mex.bat is in your PATH. With Linux, use + mex -setup.) Then configure cmake with, for example + \verbatim + cmake -G "Visual Studio 10" -D MATLAB_COMPILER=mex .. + cmake --build . --config Release --target matlabinterface \endverbatim + (Note that only the Release configuration is supported for Matlab.) + If you are running a 64-bit version of Matlab, be sure to select a + 64-bit generator with cmake, e.g., "Visual Studio 10 Win64". Finally + compile %GeographicLib with Visual Studio. (The binary installer for + 64-bit Windows includes the compiled interface built with Visual + Studio 10 and Matlab R2013a 64-bit).
+ On Linux systems, you can compile the interface for use with octave + instead by using \verbatim + cmake -D MATLAB_COMPILER=mkoctfile .. + make matlabinterface \endverbatim + - Invoking the compiler from Matlab or Octave: Start Matlab or + Octave and run, e.g., \code + mex -setup + cd 'C:/pkg-vc10-x64/GeographicLib-1.34/matlab' + help geographiclibinterface + geographiclibinterface('C:/pkg-vc10/GeographicLib-1.34'); + addpath(pwd); + \endcode + The first command allows you to select the compiler to use (which + should be the same as that used to compile %GeographicLib). + +To use the interface routines for %GeographicLib, run one of (for +example) \verbatim + addpath /usr/local/libexec/GeographicLib/matlab + addpath 'C:/pkg-vc10-x64/GeographicLib-1.34/libexec/GeographicLib/matlab' +\endverbatim +in Octave or Matlab. The available functions are: + - geodesicdirect: solve direct geodesic problem + (see GeographicLib::Geodesic::Direct) + - geodesicinverse: solve inverse geodesic problem + (see GeographicLib::Geodesic::Inverse) + - geodesicline: compute points along a geodesic + (see GeographicLib::GeodesicLine::Position) + - polygonarea: compute area of a geodesic polygon + (see GeographicLib::PolygonArea) + - utmupsforward: convert geographic coordinates to UTM/UPS + (see GeographicLib::UTMUPS::Forward) + - utmupsreverse: convert UTM/UPS coordinates to geographic + (see GeographicLib::UTMUPS::Reverse) + - mgrsforward: convert UTM/UPS coordinates to MGRS + (see GeographicLib::MGRS::Forward) + - mgrsreverse: convert MGRS coordinates to UTM/UPS + (see GeographicLib::MGRS::Reverse) + - geoidheight: compute geoid height + (see GeographicLib::Geoid::operator()()) + - geocentricforward: convert geographic coordinates to geocentric + (see GeographicLib::Geocentric::Forward) + - geocentricreverse: convert geocentric coordinates to geographic + (see GeographicLib::Geocentric::Reverse) + - localcartesianforward: convert geographic coordinates to local cartesian + (see GeographicLib::LocalCartesian::Forward) + - localcartesianreverse: convert local cartesian coordinates to geographic + (see GeographicLib::LocalCartesian::Reverse) + . +These routines just offer a simple interface to the corresponding C++ +class. Use the help function to get documentation, e.g., \code + help geodesicdirect \endcode +Unfortunately, the help function does not work for compiled functions in +Octave; in this case, just list the .m file, e.g., \code + type geodesicdirect \endcode +Other useful functions, e.g., to convert from geographic +coordinates to MGRS can easily be written with Matlab code. + +Note that geoidheight, when compiled with Visual Studio 2008 causes +Matlab to crash. (The problem does not occur with Visual Studio 2005 or +Visual Studio 2010.) + +\section maxima Maxima routines + +Maxima is a free computer algebra system which can be downloaded from +http://maxima.sf.net. Maxima was used to generate the series used by +GeographicLib::TransverseMercator ( +tmseries.mac) and GeographicLib::Geodesic ( +geod.mac) and to generate accurate data for testing +( tm.mac and +geodesic.mac). The latter uses Maxima's bigfloat arithmetic +together with series extended to high order or solutions in terms of +elliptic integrals ( ellint.mac). These files +contain brief instructions on how to use them. + +\section dotnet .NET wrapper + +This is a comprehensive wrapper library, written and maintained by Scott +Heiman, which exposes all of the functionality of %GeographicLib to the +.NET family of languages. For documentation, see + - NETGeographicLib .NET wrapper library. + +

+**********************************************************************/ +/** +\page geoid Geoid height + +
+Back to \ref other. Forward to \ref gravity. Up to \ref contents. +
+ +The gravitational equipotential surface approximately coinciding with +mean sea level is called the geoid. The GeographicLib::Geoid class and +the GeoidEval utility evaluate the height +of the geoid above the WGS84 ellipsoid. This can be used to convert +heights above mean sea level to heights above the WGS84 ellipsoid. +Because the normal to the ellipsoid differs from the normal to the geoid +(the direction of a plumb line) there is a slight ambiguity in the +measurement of heights; however for heights up to 10 km this ambiguity +is only 1 mm. + +The geoid is usually approximated by an "earth gravity model" (EGM). +The models published by the NGA are: +- EGM84: + http://earth-info.nga.mil/GandG/wgs84/gravitymod/wgs84_180/wgs84_180.html +- EGM96: + http://earth-info.nga.mil/GandG/wgs84/gravitymod/egm96/egm96.html +- EGM2008: + http://earth-info.nga.mil/GandG/wgs84/gravitymod/egm2008 +. +GeographicLib::Geoid offers a uniform way to handle all 3 geoids at a +variety of grid resolutions. (In contrast, the software tools that NGA +offers are different for each geoid, and the interpolation programs are +different for each grid resolution. In addition these tools are written +in Fortran with is nowadays difficult to integrate with other software.) + +Unlike other components of %GeographicLib, there is a appreciable error +in the results obtained (at best, the RMS error is 1 mm). However the +class provides methods to report the maximum and RMS errors in the +results. The class also returns the gradient of the geoid. This can be +used to estimate the direction of a plumb line relative to the WGS84 +ellipsoid. + +The GeographicLib::GravityModel class calculates geoid heights using the +underlying gravity model. This is slower then GeographicLib::Geoid but +considerably more accurate. This class also can accurately compute all +the components of the acceleration due to gravity (and hence the +direction of plumb line). + +Go to + - \ref geoidinst + - \ref geoidformat + - \ref geoidinterp + - \ref geoidcache + - \ref testgeoid + +\section geoidinst Installing the geoid datasets + +The geoid heights are computed using interpolation into a rectangular +grid. The grids are read from data files which have been are computed +using the NGA synthesis programs in the case of the EGM84 and EGM96 +models and using the NGA binary gridded data files in the case of +EGM2008. These data files are available for download: +

+The "size" column is the size of the uncompressed data and it also +gives the memory requirements for caching the entire dataset using the +GeographicLib::Geoid::CacheAll method. +At a minimum you should install egm96-5 and either egm2008-1 or +egm2008-2_5. Many applications use the EGM96 geoid, however the use of +EGM2008 is growing. (EGM84 is rarely used now.) + +For Linux and Unix systems, %GeographicLib provides a shell script +geographiclib-get-geoids (typically installed in /usr/local/sbin) which +automates the process of downloading and installing the geoid data. For +example +\verbatim + geographiclib-get-geoids best # to install egm84-15, egm96-5, egm2008-1 + geographiclib-get-geoids -h # for help +\endverbatim +This script should be run as a user with write access to the +installation directory, which is typically +/usr/local/share/GeographicLib (this can be overridden with the -p +flag), and the data will then be placed in the "geoids" subdirectory. + +Windows users should download and run the Windows installers. These +will prompt for an installation directory with the default being one of +\verbatim + C:/Documents and Settings/All Users/Application Data/GeographicLib + C:/ProgramData/GeographicLib +\endverbatim +(which you probably should not change) and the data is installed in the +"geoids" sub-directory. (The second directory name is an alternate name +that Windows 7 uses for the "Application Data" directory.) + +Otherwise download \e either the tar.bz2 file \e or the zip file (they +have the same contents). If possible use the tar.bz2 files, since these +are compressed about 2 times better than the zip file. To unpack these, +run, for example +\verbatim + mkdir -p /usr/local/share/GeographicLib + tar xofjC egm96-5.tar.bz2 /usr/local/share/GeographicLib + tar xofjC egm2008-2_5.tar.bz2 /usr/local/share/GeographicLib + etc. +\endverbatim +and, again, the data will be placed in the "geoids" subdirectory. + +However you install the geoid data, all the datasets should +be installed in the same directory. GeographicLib::Geoid and +GeoidEval uses a compile time default to +locate the datasets. This is +- /usr/local/share/GeographicLib/geoids, for non-Windows systems +- C:/Documents and Settings/All Users/Application Data/GeographicLib/geoids, + for Windows systems +. +consistent with the examples above. This may be overridden at run-time +by defining the GEOID_PATH or the GEOGRAPHICLIB_DATA environment variables; +see GeographicLib::Geoid::DefaultGeoidPath() for details. Finally, the +path may be set using the optional second argument to the +GeographicLib::Geoid constructor or with the "-d" flag to +GeoidEval. Supplying the "-h" flag to +GeoidEval reports the default geoid path +for that utility. The "-v" flag causes GeoidEval to report the full +path name of the data file it uses. + +\section geoidformat The format of the geoid data files + +The gridded data used by the GeographicLib::Geoid class is stored in +16-bit PGM files. Thus the data for egm96-5 might be stored in the file +- /usr/local/share/GeographicLib/geoids/egm96-5.pgm +. +PGM simple graphic format with the following properties +- it is well documented + here; +- there are no separate "little-endian" and "big-endian" versions; +- it uses 1 or 2 bytes per pixel; +- pixels can be randomly accessed; +- comments can be added to the file header; +- it is sufficiently simple that it can be easily read without using the + libnetpbm + library (and thus we avoid adding a software dependency to + %GeographicLib). +. +The major drawback of this format is that since there are only 65535 +possible pixel values, the height must be quantized to 3 mm. However, +the resulting quantization error (up to 1.5 mm) is typically smaller +than the linear interpolation errors. The comments in the header for +egm96-5 are +\verbatim + # Geoid file in PGM format for the GeographicLib::Geoid class + # Description WGS84 EGM96, 5-minute grid + # URL http://earth-info.nga.mil/GandG/wgs84/gravitymod/egm96/egm96.html + # DateTime 2009-08-29 18:45:03 + # MaxBilinearError 0.140 + # RMSBilinearError 0.005 + # MaxCubicError 0.003 + # RMSCubicError 0.001 + # Offset -108 + # Scale 0.003 + # Origin 90N 0E + # AREA_OR_POINT Point + # Vertical_Datum WGS84 +\endverbatim +Of these lines, the Scale and Offset lines are required and define the +conversion from pixel value to height (in meters) using \e height = +\e offset + \e scale \e pixel. The Geoid constructor also reads the +Description, DateTime, and error lines (if present) and stores the +resulting data so that it can be returned by +GeographicLib::Geoid::Description, GeographicLib::Geoid::DateTime, +GeographicLib::Geoid::MaxError, and GeographicLib::Geoid::RMSError +methods. The other lines serve as additional documentation but are not +used by this class. Accompanying egm96-5.pgm (and similarly with the +other geoid data files) are two files egm96-5.wld and +egm96-5.pgm.aux.xml. The first is an ESRI "world" file and the second +supplies complete projection metadata for use by +GDAL. Neither of these files is read +by GeographicLib::Geoid. + +You can use gdal_translate to convert the data files to a standard +GeoTiff, e.g., with +\verbatim + gdal_translate -ot Float32 -scale 0 65000 -108 87 egm96-5.pgm egm96-5.tif +\endverbatim +The arguments to -scale here are specific to the Offset and Scale +parameters used in the pgm file (note 65000 * 0.003 - 108 = 87). You +can check these by running GeoidEval with +the "-v" option. + +Here is a sample script which uses GDAL to create a 1-degree +squared grid of geoid heights at 3" resolution (matching DTED1) by +bilinear interpolation. +\verbatim + #! /bin/sh + lat=37 + lon=067 + res=3 # resolution in seconds + TEMP=`mktemp junkXXXXXXXXXX` # temporary file for GDAL + gdalwarp -q -te `echo $lon $lat $res | awk '{ + lon = $1; lat = $2; res = $3; + printf "%.14f %.14f %.14f %.14f", + lon -0.5*res/3600, lat -0.5*res/3600, + lon+1+0.5*res/3600, lat+1+0.5*res/3600; + }'` -ts $((3600/res+1)) $((3600/res+1)) -r bilinear egm96-5.tif $TEMP + gdal_translate -quiet \ + -mo AREA_OR_POINT=Point \ + -mo Description="WGS84 EGM96, $res-second grid" \ + -mo Vertical_Datum=WGS84 \ + -mo Tie_Point_Location=pixel_corner \ + $TEMP e$lon-n$lat.tif + rm -f $TEMP +\endverbatim + +Because the pgm files are uncompressed, they can take up a lot of disk +space. Some compressed formats compress in tiles and so might be +compatible with the requirement that the data can be randomly accessed. +In particular gdal_translate can be used to convert the pgm files to +compressed tiff files with +\verbatim +gdal_translate -co COMPRESS=LZW -co PREDICTOR=2 \ + -co TILED=YES -co BLOCKXSIZE=256 -co BLOCKYSIZE=256 \ + egmyy-g.pgm egmyy-g.tif +\endverbatim +The resulting files sizes are +\verbatim + pgm tif + egm84-30 0.6 MB 0.5 MB + egm84-15 2.1 MB 1.4 MB + egm96-15 2.1 MB 1.5 MB + egm96-5 19 MB 8.5 MB + egm2008-5 19 MB 9.8 MB + egm2008-2_5 75 MB 28 MB + egm2008-1 470 MB 97 MB +\endverbatim +Currently, there are no plans for %GeographicLib to support this +compressed format. + +\section geoidinterp Interpolating the geoid data + +GeographicLib::Geoid evaluates the geoid height using bilinear or cubic +interpolation. The gradient of the geoid height is obtained by +differentiating the interpolated height and referencing the result to +distance on the WGS84 ellipsoid. + +WARNING: Although GeographicLib::Geoid computes the gradient of +the geoid height, this is subject to large quantization errors as a +result of the way that the geoid data is stored. This is particularly +acute for fine grids, at high latitudes, and for the easterly gradient. +If you need to compute the direction of the acceleration due to gravity +accurately, you should use GeographicLib::GravityModel::Gravity. + +The bilinear interpolation is based on the values at the 4 corners of +the enclosing cell. The interpolated height is a continuous function of +position; however the gradient has discontinuities are cell boundaries. +The quantization of the data files exacerbates the errors in the +gradients. + +The cubic interpolation is a least-squares fit to the values on a +12-point stencil with weights as follows: +\verbatim + . 1 1 . + 1 2 2 1 + 1 2 2 1 + . 1 1 . +\endverbatim +The cubic is constrained to be independent of longitude when evaluating +the height at one of the poles. Cubic interpolation is considerably +more accurate than bilinear interpolation; however, in this +implementation there are small discontinuities in the heights are cell +boundaries. The over-constrained cubic fit slightly reduces the +quantization errors on average. + +The algorithm for the least squares fit is taken from, F. H. Lesh, +Multi-dimensional least-squares polynomial curve fitting, CACM 2, 29-30 +(1959). This algorithm is not part of GeographicLib::Geoid; instead it is +implemented as +Maxima +code which is used to precompute the matrices to convert the function +values on the stencil into the coefficients from the cubic polynomial. +This code is included as a comment in Geoid.cpp. + +The interpolation methods are quick and give good accuracy. Here is a +summary of the combined quantization and interpolation errors for the +heights. +

+The errors are with respect to the specific NGA earth gravity model +(not to any "real" geoid). The RMS values are obtained using 5 million +uniformly distributed random points. The maximum values are obtained by +evaluating the errors using a different grid with points at the +centers of the original grid. (The RMS difference between EGM96 and +EGM2008 is about 0.5 m. The RMS difference between EGM84 and EGM96 is +about 1.5 m.) + +The errors in the table above include the quantization errors that arise +because the height data that GeographicLib::Geoid uses are quantized to +3 mm.

+ +\section geoidcache Caching the geoid data + +A simple way of calling Geoid is as follows +\code + #include + #include + ... + GeographicLib::Geoid g("egm96-5"); + double lat, lon; + while (std::cin >> lat >> lon) + std::cout << g(lat, lon) << "\n"; + ... +\endcode + +The first call to g(lat, lon) causes the data for the stencil points (4 +points for bilinear interpolation and 12 for cubic interpolation) to be +read and the interpolated value returned. A simple 0th-order caching +scheme is provided by default, so that, if the second and subsequent +points falls within the same grid cell, the data values are not reread +from the file. This is adequate for most interactive use and also +minimizes disk accesses for the case when a continuous track is being +followed. + +If a large quantity of geoid calculations are needed, the calculation +can be sped up by preloading the data for a rectangular block with +GeographicLib::Geoid::CacheArea or the entire dataset with +GeographicLib::Geoid::CacheAll. If the requested points lie within the +cached area, the cached data values are used; otherwise the data is read +from disk as before. Caching all the data is a reasonable choice for +the 5' grids and coarser. Caching all the data for the 1' grid will +require 0.5 GB of RAM and should only be used on systems with sufficient +memory. + +The use of caching does not affect the values returned. Because of the +caching and the random file access, this class is \e not normally thread +safe; i.e., a single instantiation cannot be safely used by multiple +threads. If multiple threads need to calculate geoid heights, there are +two alternatives: + - they should all construct thread-local instantiations. + - GeographicLib::Geoid should be constructed with \e threadsafe = true. + This causes all the data to be read at the time of construction (and + if this fails, an exception is thrown), the data file to be closed + and the single-cell caching to be turned off. The resulting object + may then be shared safely between threads. + +\section testgeoid Test data for geoids + +A test set for the geoid models is available at + - + GeoidHeights.dat.gz + . +This is about 11 MB (compressed). This test set consists of a set of +500000 geographic coordinates together with the corresponding geoid +heights according to various earth gravity models. + +Each line of the test set gives 6 space delimited numbers + - latitude (degrees, exact) + - longitude (degrees, exact) + - EGM84 height (meters, accurate to 1 μm) + - EGM96 height (meters, accurate to 1 μm) + - EGM2008 height (meters, accurate to 1 μm) + . +The latitude and longitude are all multiples of 10−6 +deg and should be regarded as exact. The geoid heights are computed +using the harmonic NGA synthesis programs, where the programs were +compiled (with gfortran) and run under Linux.

This may be overridden at run-time +by defining the GRAVITY_PATH or the GEOGRAPHICLIB_DATA environment +variables; see GeographicLib::GravityModel::DefaultGravityPath() for +details. Finally, the path may be set using the optional second +argument to the GeographicLib::GravityModel constructor or with the "-d" +flag to +Gravity. Supplying the "-h" flag to +Gravity reports the default path for +gravity models for that utility. The "-v" flag causes Gravity to report +the full path name of the data file it uses. + +\section gravityformat The format of the gravity model files + +The constructor for GeographicLib::GravityModel reads a file called +NAME.egm which specifies various properties for the gravity model. It +then opens a binary file NAME.egm.cof to obtain the coefficients of the +spherical harmonic sum. + +The first line of the .egm file must consist of "EGMF-v" where EGMF +stands for "Earth Gravity Model Format" and v is the version number of +the format (currently "1"). + +The rest of the File is read a line at a time. A # character and +everything after it are discarded. If the result is just white space it +is discarded. The remaining lines are of the form "KEY WHITESPACE +VALUE". In general, the KEY and the VALUE are case-sensitive. + +GeographicLib::GravityModel only pays attention to the following +keywords + - keywords that affect the field calculation, namely: + - ModelRadius (required), the normalizing radius for the model + in meters. + - ReferenceRadius (required), the major radius \e a for the + reference ellipsoid meters. + - ModelMass (required), the mass constant \e GM for the model + in meters3/seconds2. + - ReferenceMass (required), the mass constant \e GM for the + reference ellipsoid in meters3/seconds2. + - AngularVelocity (required), the angular velocity ω for + the model \e and the reference ellipsoid in rad + seconds−1. + - Flattening, the flattening of the reference ellipsoid; this + can be given a fraction, e.g., 1/298.257223563. One of + Flattening and DynamicalFormFactor is required. + - DynamicalFormFactor, the dynamical form factor + J2 for the reference ellipsoid. One of + Flattening and DynamicalFormFactor is required. + - HeightOffset (default 0), the constant height offset + (meters) added to obtain the geoid height. + - CorrectionMultiplier (default 1), the multiplier for the + "zeta-to-N" correction terms for the geoid height to convert them + to meters. + - Normalization (default full), the normalization used for the + associated Legendre functions (full or schmidt). + - ID (required), 8 printable characters which serve as a + signature for the .egm.cof file (they must appear as the first 8 + bytes of this file). + . + The parameters ModelRadius, ModelMass, and + AngularVelocity apply to the gravity model, while + ReferenceRadius, ReferenceMass, AngularVelocity, + and either Flattening or DynamicalFormFactor + characterize the reference ellipsoid. AngularVelocity + (because it can be measured precisely) is the same for the gravity + model and the reference ellipsoid. ModelRadius is merely a + scaling parameter for the gravity model and there's no requirement + that it be close to the major radius of the earth (although that's + typically how it is chosen). ModelMass and + ReferenceMass need not be the same and, indeed, they are + slightly difference for egm2008. As a result the disturbing + potential \e T has a 1/\e r dependence at large distances. + - keywords that store data that the user can query: + - Name, the name of the model. + - Description, a more descriptive name of the model. + - ReleaseDate, when the model was created. + - keywords that are examined to verify that their values are valid: + - ByteOrder (default little), the order of bytes in the + .egm.cof file. Only little endian is supported at present. + . +Other keywords are ignored. + +The coefficient file NAME.egm.cof is a binary file in little endian +order. The first 8 bytes of this file must match the ID given in +NAME.egm. This is followed by 2 sets of spherical harmonic +coefficients. The first of these gives the gravity potential and the +second gives the zeta-to-N corrections to the geoid height. The format +for each set of coefficients is: + - \e N, the maximum degree of the sum stored as a 4-byte signed integer. + This must satisfy \e N ≥ −1. + - \e M, the maximum order of the sum stored as a 4-byte signed integer. + This must satisfy \e N ≥ \e M ≥ −1. + - \e C\e nm, the coefficients of the cosine coefficients of + the sum in column (i.e., \e m) major order. There are (\e M + 1) + (2\e N - \e M + 2) / 2 elements which are stored as IEEE doubles (8 + bytes). For example for \e N = \e M = 3, there are 10 coefficients + arranged as + C00, + C10, + C20, + C30, + C11, + C21, + C31, + C22, + C32, + C33. + - \e S\e nm, the coefficients of the sine coefficients of + the sum in column (i.e., \e m) major order starting at \e m = 1. + There are \e M (2\e N - \e M + 1) / 2 elements which are stored as + IEEE doubles (8 bytes).

Listed here are +issues that I encountered using the NGA code: + -# A compiler which allocates local variables on the stack produces an + executable with just returns NaNs. The problem here is a missing + SAVE statement in subroutine latf. + -# Because the model and references masses for egm2008 differ (by about + 1 part in 109), there should be a 1/\e r contribution to + the disturbing potential \e T. However, this term is set to zero in + hsynth_WGS84 (effectively altering the normal potential). This + shifts the surface \e W = U0 outward by about 5 mm. + Note too that the reference ellipsoid is no longer a level surface of + the effective normal potential. + -# Subroutine radgrav computes the ellipsoidal coordinate + β incorrectly. This leads to small errors in the deflection + of the vertical, ξ and η, when the height above the + ellipsoid, \e h, is non-zero (about 10−7 arcsec at + \e h = 400 km). + -# There are several expressions which will return inaccurate results + due to cancellation. For example, subroutine grs + computes the flattening using \e f = 1 - sqrt(1 - + e2). Much better is to use \e f = + e2/(1 + sqrt(1 - e2)). The + expressions for \e q and \e q' in grs and + radgrav suffer from similar problems. The resulting + errors are tiny (about 50 pm in the geoid height); however, given + that's there's essentially no cost to using more accurate + expressions, it's preferable to do so. + -# hsynth_WGS84 returns an "undefined" value for \e xi and \e eta at the + poles. Better would be to return the value obtained by taking the + limit \e lat -> +/- 90°. + . +Issues 1--4 have been reported to the authors of hsynth_WGS84. +Issue 1 is peculiar to Fortran and is not encountered in C++ code and +GeographicLib::GravityModel corrects issues 3--5. On issue 2, +GeographicLib::GravityModel neglects the 1/\e r term in \e T in +GeographicLib::GravityModel::GeoidHeight and +GeographicLib::GravityModel::SphericalAnomaly in order to produce +results which match NGA's for these quantities. On the other hand, +GeographicLib::GravityModel::Disturbance and +GeographicLib::GravityModel::T do include this term. + +\section gravitygeoid Details of the geoid height and anomaly calculations + +Ideally, the geoid represents a surface of constant gravitational +potential which approximates mean sea level. In reality some +approximations are taken in determining this surface. The steps taking +by GeographicLib::GravityModel in computing the geoid height are +described here (in the context of EGM2008). This mimics NGA's code +hsynth_WGS84 closely because most users of EGM2008 use the gridded data +generated by this code (e.g., GeographicLib::Geoid) and it is desirable +to use a consistent definition of the geoid height. + - The model potential is band limited; the minimum wavelength that is + represented is 360°/2160 = 10' (i.e., about 10NM or + 18.5km). The maximum degree for the spherical harmonic sum is 2190; + however the model was derived using ellipsoidal harmonics of degree + and order 2160 and the degree was increased to 2190 in order to + capture the ellipsoidal harmonics faithfully with spherical + harmonics. + - The 1/\e r term is omitted from the \e T (this is issue 2 in \ref + gravitynga). This moves the equipotential surface by about 5mm. + - The surface \e W = U0 is determined by Bruns' + formula, which is roughly equivalent to a single iteration of + Newton's method. The RMS error in this approximation is about 1.5mm + with a maximum error of about 10 mm. + - The model potential is only valid above the earth's surface. A + correction therefore needs to be included where the geoid lies + beneath the terrain. This is NGA's "zeta-to-N" correction, which is + represented by a spherical harmonic sum of degree and order 2160 (and + so it misses short wavelength terrain variations). In addition, it + entails estimating the isostatic equilibrium of the earth's crust. + The correction lies in the range [-5.05 m, 0.05 m], however for 99.9% + of the earth's surface the correction is less than 10 mm in + magnitude. + - The resulting surface lies above the observed mean sea level, + so -0.41m is added to the geoid height. (Better would be to change + the potential used to define the geoid; but this would only change + the result by about 2mm.) + . +A useful discussion of the problems with defining a geoid is given by +Dru A. Smith in + +There is no such thing as "The" EGM96 geoid: Subtle points on the use of +a global geopotential model, IGeS Bulletin No. 8, International +Geoid Service, Milan, Italy, pp. 17--28 (1998). + +GeographicLib::GravityModel::GeoidHeight reproduces the results of the +several NGA codes for harmonic synthesis with the following maximum +discrepancies: + - egm84 = 1.1mm. This is probably due to inconsistent parameters for the + reference ellipsoid in the NGA code. (In particular, the value of + mass constant excludes the atmosphere; however, it's not clear + whether the other parameters have been correspondingly adjusted.) + Note that geoid heights predicted by egm84 differ from those of more + recent gravity models by about 1 meter. + - egm96 = 23nm. + - egm2008 = 78pm. After addressing some of the issues alluded to in + issue 4 in \ref gravitynga, the maximum discrepancy becomes 23pm. + +The formula for the gravity anomaly vector involves computing gravity +and normal gravity at two different points (with the displacement +between the points unknown ab initio). Since the gravity anomaly +is already a small quantity it is sometimes acceptable to employ +approximations that change the quantities by \e O(\e f). The NGA code +uses the spherical approximation described by Heiskanen and Moritz, +Sec. 2-14 and GeographicLib::GravityModel::SphericalAnomaly uses the +same approximation for compatibility. In this approximation, the +gravity disturbance delta = grad \e T is calculated. +Here, \e T once again excludes the 1/\e r term (this is issue 2 in \ref +gravitynga and is consistent with the computation of the geoid height). +Note that delta compares the gravity and the normal gravity at +the \e same point; the gravity anomaly vector is then found by +estimating the gradient of the normal gravity in the limit that the +earth is spherically symmetric. delta is expressed in \e +spherical coordinates as \e deltax, \e deltay, \e deltaz where, for +example, \e deltaz is the \e radial component of delta (not the +component perpendicular to the ellipsoid) and \e deltay is similarly +slightly different from the usual northerly component. The components +of the anomaly are then given by + - gravity anomaly, \e Dg01 = \e deltaz - 2T/\e R, where \e R + distance to the center of the earth; + - northerly component of the deflection of the vertical, \e xi = - + deltay/\e gamma, where \e gamma is the magnitude of the normal + gravity; + - easterly component of the deflection of the vertical, \e eta = - + deltax/\e gamma. + . +GeographicLib::NormalGravity computes the normal gravity accurately and +avoids issue 3 of \ref gravitynga. Thus while +GeographicLib::GravityModel::SphericalAnomaly reproduces the results for +\e xi and \e eta at \e h = 0, there is a slight discrepancy if \e h is +non-zero. + +\section gravityatmos The effect of the mass of the atmosphere + +All of the supported models use WGS84 for the reference ellipsoid. This +has (see + +TR8350.2, table 3.1) + - \e a = 6378137 m + - \e f = 1/298.257223563 + - ω = 7292115 × 10−11 rad + s−1 + - \e GM = 3986004.418 × 108 m3 + s−2. + . +The value of \e GM includes the mass of the atmosphere and so strictly +only applies above the earth's atmosphere. Near the surface of the +earth, the value of \e g will be less (in absolute value) than the value +predicted by these models by about δ\e g = (4πG/\e +g) \e A = 8.552 × 10−11 \e A m2/kg, +where \e G is the gravitational constant, \e g is the earth's gravity, +and \e A is the pressure of the atmosphere. At sea level we have \e A = +101.3 kPa, and δ\e g = 8.7 × 10−6 m +s−2, approximately. (In other words the effect is +about 1 part in a million; by way of comparison, buoyancy effects +are about 100 times larger.) + +\section gravityparallel Geoid heights on a multi-processor system + +The egm2008 model includes many terms (over 2 million spherical +harmonics). For that reason computations using this model may be slow; +for example it takes about 78 ms to compute the geoid height at a single +point. There are two ways to speed up this computation: + - Use a GeographicLib::GravityCircle to compute the geoid height at + several points on a circle of latitude. This reduces the cost per + point to about 92 μs (a reduction by a factor of over 800). + - Compute the values on several circles of latitude in parallel. One + of the simplest ways of doing this is with + OpenMP; on an 8-processor system, + this can speed up the computation by another factor of 8. + . +Both of these techniques are illustrated by the following code, +which computes a table of geoid heights on +a regular grid and writes on the result in a +.gtx +file. On an 8-processor Intel 2.66 GHz machine using OpenMP +(-DHAVE_OPENMP=1), it takes about 40 minutes of elapsed time to compute +the geoid height for EGM2008 on a 1' gride. (Without these +optimizations, the computation would have taken about 200 days!) +\include GeoidToGTX.cpp + +This example, examples/GeoidToGTX.cpp, is built if cmake +is configured with -D GEOGRAPHICLIB_EXAMPLES=ON. cmake +will add in support for OpenMP, if it is available. + +

For dates prior to 2010, + linear interpolation is used. + - Epoch (required), the time origin (in fractional years) for + the first model. + - DeltaEpoch (default 1), the interval between models in years + (only relevant for NumModels > 1). + - Normalization (default schmidt), the normalization used for + the associated Legendre functions (schmidt or full). + - ID (required), 8 printable characters which serve as a + signature for the .wmm.cof file (they must appear as the first 8 + bytes of this file). + - keywords that store data that the user can query: + - Name, the name of the model. + - Description, a more descriptive name of the model. + - ReleaseDate, when the model was created. + - MinTime, the minimum date at which the model should be used. + - MaxTime, the maximum date at which the model should be used. + - MinHeight, the minimum height above the ellipsoid for which + the model should be used. + - MaxHeight, the maximum height above the ellipsoid for which + the model should be used. + . + GeographicLib::MagneticModel does not enforce the restrictions + implied by last four quantities. However, + MagneticField issues a warning if + these limits are exceeded. + - keywords that are examined to verify that their values are valid: + - Type (default linear), the type of the model. "linear" + means that the time variation is piece-wise linear (either using + interpolation between the field at two dates or using the field and + its first derivative with respect to time). This is the only type + of model supported at present. + - ByteOrder (default little), the order of bytes in the + .wmm.cof file. Only little endian is supported at present. + . +Other keywords are ignored. + +The coefficient file NAME.wmm.cof is a binary file in little endian +order. The first 8 bytes of this file must match the ID given in +NAME.wmm. This is followed by NumModels + 1 sets of spherical harmonic +coefficients. The first NumModels of these model the magnetic field at +Epoch + \e i * DeltaEpoch for 0 ≤ \e i < NumModels. The last set of +coefficients model the rate of change of the magnetic field at Epoch + +(NumModels − 1) * DeltaEpoch. The format for each set of coefficients +is: + - \e N, the maximum degree of the sum stored as a 4-byte signed integer. + This must satisfy \e N ≥ −1. + - \e M, the maximum order of the sum stored as a 4-byte signed integer. + This must satisfy \e N ≥ \e M ≥ −1. + - \e C\e nm, the coefficients of the cosine coefficients of + the sum in column (i.e., \e m) major order. There are (\e M + 1) + (2\e N − \e M + 2) / 2 elements which are stored as IEEE doubles (8 + bytes). For example for \e N = \e M = 3, there are 10 coefficients + arranged as + C00, + C10, + C20, + C30, + C11, + C21, + C31, + C22, + C32, + C33. + - \e S\e nm, the coefficients of the sine coefficients of + the sum in column (i.e., \e m) major order starting at \e m = 1. + There are \e M (2\e N − \e M + 1) / 2 elements which are stored as + IEEE doubles (8 bytes). For example for \e N = \e M = 3, there are 6 + coefficients arranged as + S11, + S21, + S31, + S22, + S32, + S33. + . +Although the coefficient file is in little endian order, %GeographicLib +can read it on big endian machines.

+ +GeographicLib::Geodesic and GeographicLib::GeodesicLine provide accurate +solutions to the direct and inverse geodesic problems. The +GeodSolve utility provides an interface +to these classes. GeographicLib::AzimuthalEquidistant implements the +azimuthal equidistant projection in terms of geodesics. +GeographicLib::CassiniSoldner implements a transverse cylindrical +equidistant projection in terms of geodesics. The GeodesicProj utility provides an +interface to these projections. + +The algorithms used by GeographicLib::Geodesic and +GeographicLib::GeodesicLine are based on a Taylor expansion of the +geodesic integrals valid when the flattening \e f is small. +GeographicLib::GeodesicExact and GeographicLib::GeodesicLineExact +evaluate the integrals exactly (in terms of incomplete elliptic +integrals). For the WGS84 ellipsoid, the series solutions are about +2--3 times faster and 2--3 times more accurate (because it's easier to +control round-off errors with series solutions); thus +GeographicLib::Geodesic and GeographicLib::GeodesicLine are +recommended for most geodetic applications. However, in applications +where the absolute value of \e f is greater than about 0.02, the exact +classes should be used. + +Go to + - \ref testgeod + - \ref geodseries + - \ref geodellip + - \ref meridian + - \ref geodshort + . +For some background information on geodesics on triaxial ellipsoids, see +\ref triaxial. + +References + - F.

The distance \e s12 always +corresponds to an arc length \e a12 ≤ 180°, so the given +geodesics give the shortest paths from point 1 to point 2. For +simplicity and without loss of generality, \e lat1 is chosen in +[0°, 90°], \e lon1 is taken to be zero, \e azi1 is +chosen in [0°, 180°]. Furthermore, \e lat1 and \e +azi1 are taken to be multiples of 10−12 deg and \e s12 +is a multiple of 0.1 μm in [0 m, 20003931.4586254 m]. This results \e +lon2 in [0°, 180°] and \e azi2 in [0°, 180°]. + +The direct calculation uses an expansion of the geodesic equations +accurate to f30 (approximately 1 part in 1050) +and is computed with with +Maxima's +bfloats and fpprec set to 100 (so the errors in the data are probably +1/2 of the values quoted above). + +The contents of the file are as follows: + - 100000 entries randomly distributed + - 50000 entries which are nearly antipodal + - 50000 entries with short distances + - 50000 entries with one end near a pole + - 50000 entries with both ends near opposite poles + - 50000 entries which are nearly meridional + - 50000 entries which are nearly equatorial + - 50000 entries running between vertices (\e azi1 = \e azi2 = 90°) + - 50000 entries ending close to vertices + . +(a total of 500000 entries). The values for \e s12 for the geodesics +running between vertices are truncated to a multiple of 0.1 pm and this +is used to determine point 2. + +This data can be fed to the GeodSolve +utility as follows + - Direct from point 1: +\verbatim + gunzip -c GeodTest.dat.gz | cut -d' ' -f1,2,3,7 | ./GeodSolve +\endverbatim + This should yield columns 4, 5, 6, and 9 of the test set. + - Direct from point 2: +\verbatim + gunzip -c GeodTest.dat.gz | cut -d' ' -f4,5,6,7 | + sed "s/ \([^ ]*$\)/ -\1/" | ./GeodSolve +\endverbatim + (The sed command negates the distance.)

Adding "-f" causes GeodSolve to print 12 fields specifying +the geodesic; these include the 10 fields in the test set plus the +geodesic scales \e M12 and \e M21 which are inserted between \e m12 and +\e S12. + +Code for computing arbitrarily accurate geodesics in maxima is available +in geodesic.mac (this depends on + ellint.mac and uses the series computed by + geod.mac). This solve both the direct and +inverse geodesic problems and offers the ability to solve the problems +either using series expansions (similar to GeographicLib::Geodesic) or +in terms of elliptic integrals (similar to +GeographicLib::GeodesicExact). + +\section geodseries Expansions for geodesics + +We give here the series expansions for the various geodesic integrals +valid to order f10. In this release of the code, we +use a 6th-order expansions. This is sufficient to maintain accuracy +for doubles for the SRMmax ellipsoid (\e a = 6400 km, \e f = 1/150). +However, the preprocessor macro GEOGRAPHICLIB_GEODESIC_ORDER can be +used to select any order up to 8.

The formula for \f$ s \f$ and the +first expression for \f$ \lambda \f$ are given by Legendre (1811) and +are the most common representation of geodesics in terms of elliptic +integrals. The second (equivalent) expression for \f$ \lambda \f$, +which was given by Cayley (1870), is useful in that the elliptic +integral is relegated to a small correction term. This form allows +the longitude to be computed more accurately and is used in +%GeographicLib.

Additional work +planned for this aspect of the geodesic problem: +- formulate the area integral \e S12 in terms of elliptic integrals; +- generate accurate test geodesics for highly eccentric ellipsoids so + that the roundoff errors can be quantified. + +Thomas (1952) and Rollins (2010) use a different independent variable +for geodesics, \f$\theta\f$ instead of \f$\sigma\f$, where \f$ +\tan\theta = \sqrt{1 + k^2} \tan\sigma \f$.

Rapp, + + Geometric Geodesy, Part I, Ohio State Univ. (1991), Sec. 6.5. + +Bowring considers the conformal mapping of the ellipsoid to a sphere of +radius \f$ R \f$ such that circles of latitude and meridians are +preserved (and hence the azimuth of a line is preserved). Let \f$ +(\phi, \lambda) \f$ and \f$ (\phi', \lambda') \f$ be the latitude and +longitude on the ellipsoid and sphere respectively. Define isometric +latitudes for the sphere and the ellipsoid as +\f[ +\begin{aligned} + \psi' &= \sinh^{-1} \tan \phi', \\ + \psi &= \sinh^{-1} \tan \phi - e \tanh^{-1}(e \sin\phi). +\end{aligned} +\f] +The most general conformal mapping satisfying Bowring's conditions is +\f[ +\psi' = A \psi + K, \quad \lambda' = A \lambda, +\f] +where \f$ A \f$ and \f$ K \f$ are constants. (In fact a constant can be +added to the equation for \f$ \lambda' \f$, but this does affect the +analysis.) The scale of this mapping is +\f[ +m(\phi) = \frac{AR}{\nu}\frac{\cos\phi'}{\cos\phi}, +\f] +where \f$ \nu = a/\sqrt{1 - e^2\sin^2\phi} \f$ is the transverse radius +of curvature. (Note that in Bowring's Eq. (10), \f$ \phi \f$ should be +replaced by \f$ \phi' \f$.) The mapping from the ellipsoid to the sphere +depends on three parameters \f$ R, A, K \f$. These will be selected to +satisfy certain conditions at some representative latitude \f$ \phi_0 +\f$. Two possible choices are given below. + +\subsection bowring Bowring's method + +Bowring (1981) requires that +\f[ +m(\phi_0) = 1,\quad +\left.\frac{dm(\phi)}{d\phi}\right|_{\phi=\phi_0} = 0,\quad +\left.\frac{d^2m(\phi)}{d\phi^2}\right|_{\phi=\phi_0} = 0, +\f] +i.e, \f$m\approx 1\f$ in the vicinity of \f$\phi = \phi_0\f$. +This gives +\f[ +\begin{aligned} +R &= \frac{\sqrt{1 + e'^2}}{B^2} a, \\ +A &= \sqrt{1 + e'^2 \cos^4\phi_0}, \\ +\tan\phi'_0 &= \frac1B \tan\phi_0, +\end{aligned} +\f] +where \f$ e' = e/\sqrt{1-e^2} \f$ is the second eccentricity, \f$ B = +\sqrt{1+e'^2\cos^2\phi_0} \f$, and \f$ K \f$ is defined implicitly by +the equation for \f$\phi'_0\f$. The radius \f$ R \f$ is the (Gaussian) +mean radius of curvature of the ellipsoid at \f$\phi_0\f$ (so near +\f$\phi_0\f$ the ellipsoid can be deformed to fit the sphere snugly). +The third derivative of \f$ m \f$ is given by +\f[ +\left.\frac{d^3m(\phi)}{d\phi^3}\right|_{\phi=\phi_0} = +\frac{-2e'^2\sin2\phi_0}{B^4}. +\f] + +The method for solving the inverse problem between two nearby points \f$ +(\phi_1, \lambda_1) \f$ and \f$ (\phi_2, \lambda_2) \f$ is as follows: +Set \f$\phi_0 = (\phi_1 + \phi_2)/2\f$. Compute \f$ R, A, \phi'_0 \f$, +and hence find \f$ (\phi'_1, \lambda'_1) \f$ and \f$ (\phi'_2, +\lambda'_2) \f$. Finally, solve for the great circle on a sphere of +radius \f$ R \f$; the resulting distance and azimuths are good +approximations for the corresponding quantities for the ellipsoidal +geodesic. + +Consistent with the accuracy of this method, we can compute +\f$\phi'_1\f$ and \f$\phi'_2\f$ using a Taylor expansion about +\f$\phi_0\f$. This also avoids numerical errors that arise from +subtracting nearly equal quantities when using the equation for +\f$\phi'\f$ directly. Write \f$\Delta \phi = \phi - \phi_0\f$ and +\f$\Delta \phi' = \phi' - \phi'_0\f$; then we have +\f[ +\Delta\phi' \approx +\frac{\Delta\phi}B \biggl[1 + +\frac{\Delta\phi}{B^2}\frac{e'^2}2 + \biggl(3\sin\phi_0\cos\phi_0 + + \frac{\Delta\phi}{B^2} + \bigl(B^2 - \sin^2\phi_0(2 - 3 e'^2 \cos^2\phi_0)\bigr)\biggr)\biggr], +\f] +where the error is \f$O(f\Delta\phi^4)\f$. +This is essentially Bowring's method. Significant differences between +this result, "Bowring (improved)", compared to Bowring's paper, "Bowring +(original)", are: + - Bowring elects to use \f$\phi_0 = \phi_1\f$. This simplifies the + calculations somewhat but increases the error by about a factor of + 4. + - Bowring's expression for \f$ \Delta\phi' \f$ is only accurate in the + limit \f$ e' \rightarrow 0 \f$. + . +In fact, arguably, the highest order \f$O(f\Delta\phi^3)\f$ terms should +be dropped altogether. Their inclusion does result in a better estimate +for the distance. However, if your goal is to generate both accurate +distances \e and accurate azimuths, then \f$\Delta\phi\f$ needs to be +restricted sufficiently to allow these terms to be dropped to give the +"Bowring (truncated)" method. + +With highly eccentric ellipsoids, the parametric latitude \f$ \beta \f$ +is a better behaved independent variable to use. In this case, \f$ +\phi_0 \f$ is naturally defined using \f$\beta_0 = (\beta_1 + +\beta_2)/2\f$ and in terms of \f$\Delta\beta = \beta - \beta_0\f$, we +have +\f[ +\Delta\phi' \approx +\frac{\Delta\beta}{B'} \biggl[1 + +\frac{\Delta\beta}{B'^2}\frac{e'^2}2 + \biggl(\sin\beta_0\cos\beta_0 + + \frac{\Delta\beta}{3B'^2} + \bigl( \cos^2\beta_0 - \sin^2\beta_0 B'^2\bigr) +\biggr)\biggr], +\f] +where \f$B' = \sqrt{1+e'^2\sin^2\beta_0} = \sqrt{1+e'^2}/B\f$, and the +error once again is \f$O(f\Delta\phi^4)\f$. This is the "Bowring +(using \f$\beta\f$)" method. + +\subsection auxsphere Bessel's auxiliary sphere + +%GeographicLib's uses the auxiliary sphere method of Legendre, Bessel, +and Helmert. For short geodesics, this is equivalent to picking +\f$ R, A, K \f$ so that +\f[ +m(\phi_0) = 1,\quad +\left.\frac{dm(\phi)}{d\phi}\right|_{\phi=\phi_0} = 0,\quad +\tan\phi'_0 = (1 - f) \tan\phi_0. +\f] +Bowring's requirement that the second derivative of \f$m\f$ vanish has +been replaced by the last relation which states that \f$\phi'_0 = +\beta_0\f$, the parametric latitude corresponding to \f$\phi_0\f$. This +gives +\f[ +\begin{aligned} +R &= B'(1-f)a, \\ +A &= \frac1{B'(1-f)}, \\ +\left.\frac{d^2m(\phi)}{d\phi^2}\right|_{\phi=\phi_0} &= +-e^2B'^2\sin^2\phi_0. +\end{aligned} +\f] + +Similar to Bowring's method, we can compute \f$\phi'_1\f$ and +\f$\phi'_2\f$ using a Taylor expansion about \f$\beta_0\f$. This results +in the simple expression +\f[ +\Delta\phi' \approx \Delta\beta, +\f] +where the error is \f$O(f\Delta\beta^2)\f$. + +\subsection shorterr Estimating the accuracy + +In assessing the accuracy of these methods we use two metrics: + - The absolute error in the distance. + - The consistency of the predicted azimuths. Imagine starting + ellipsoidal geodesics at \f$ (\phi_1, \lambda_1) \f$ and \f$ (\phi_2, + \lambda_2) \f$ with the predicted azimuths. What is the distance + between them when they are extended a distance \f$ a \f$ beyond the + second point? + . +(The second metric is much more stringent.) We may now compare the +methods by asking for a bound to the length of a geodesic which ensures +that the one or other of the errors fall below 1 mm (an "engineering" +definition of accurate) or 1 nm (1 nanometer, about the round-off +limit). + +

+ +Jacobi (1839) showed that the problem of geodesics on a triaxial +ellipsoid (with 3 unequal axes) can be reduced to quadrature.

\n +Fig. 1: +The ellipsoidal grid. The blue (resp. green) lines are lines of constant +\f$\beta\f$ (resp. \f$\omega\f$); the grid spacing is 10°. Also +shown in red are two of the principal sections of the ellipsoid, defined +by \f$x = 0\f$ and \f$z = 0\f$. The third principal section, \f$y = +0\f$, is covered by the lines \f$\beta = \pm 90^\circ\f$ and \f$\omega = +90^\circ \pm 90^\circ\f$. These lines meet at four umbilical points (two +of which are visible in this figure) where the principal radii of +curvature are equal. The parameters of the ellipsoid are \f$a = +1.01\f$, \f$b = 1\f$, \f$c = 0.8\f$, and it is viewed in an orthographic +projection from a point above \f$\phi = 40^\circ\f$, \f$\lambda = +30^\circ\f$. These parameters were chosen to accentuate the ellipsoidal +effects on geodesics (relative to those on the earth) while still +allowing the connection to an ellipsoid of revolution to be made. + +The grid lines of the ellipsoid coordinates are "lines of curvature" on +the ellipsoid, i.e., they are parallel to the direction of principal +curvature (Monge, 1796). They are also intersections of the ellipsoid +with confocal systems of hyperboloids of one and two sheets (Dupin, +1813). Finally they are geodesic ellipses and hyperbolas defined using +two adjacent umbilical points. For example, the lines of constant +\f$\beta\f$ in Fig. 1 can be generated with the familiar string +construction for ellipses with the ends of the string pinned to the two +umbilical points. + +Inter-conversions between these three latitudes and longitudes and the +cartesian coordinates are simple algebraic exercises. + +\section triaxial-jacobi Jacobi's solution + +Solving the geodesic problem for an ellipsoid of revolution is, from the +mathematical point of view, trivial; because of symmetry, geodesics have +a constant of the motion (analogous to the angular momentum) which was +found by Clairaut (1733). By 1806 (with the work of Legendre, Oriani, +et al.), there was a complete understanding of the qualitative behavior +of geodesics on an ellipsoid of revolution. + +On the other hand, geodesics on a triaxial ellipsoid have no obvious +constant of the motion and thus represented a challenging "unsolved" +problem in the first half of the nineteenth century. Jacobi discovered +that the geodesic equations are separable if they are expressed in +ellipsoidal coordinates. You can get an idea of the importance Jacobi +attached to his discovery from the + +letter he wrote to his friend and neighbor Bessel: +
The day before yesterday, I reduced to quadrature the +problem of geodesic lines on an ellipsoid with three unequal +axes. They are the simplest formulas in the world, Abelian +integrals, which become the well known elliptic integrals if 2 axes are +set equal.\n +Königsberg, 28th Dec. '38. +
+ +On the same day he wrote a similar letter to the editor of Compte Rendus +and his result was published in J. Crelle in (1839) with a French +translation (from German) appearing in J. Liouville in (1841). + +Here is the solution, exactly as given by Jacobi + here +(with minor changes in notation): +\f[ +\begin{aligned} +\delta &= \int \frac +{\sqrt{b^2\sin^2\beta + c^2\cos^2\beta}\,d\beta} +{\sqrt{a^2 - b^2\sin^2\beta - c^2\cos^2\beta} + \sqrt{(b^2-c^2)\cos^2\beta - \gamma}}\\ +&\quad - +\int \frac +{\sqrt{a^2\sin^2\omega + b^2\cos^2\omega}\,d\omega} +{\sqrt{a^2\sin^2\omega + b^2\cos^2\omega - c^2} + \sqrt{(a^2-b^2)\sin^2\omega + \gamma}} +\end{aligned} +\f] +As Jacobi notes "a function of the angle \f$\beta\f$ equals a +function of the angle \f$\omega\f$. These two functions are just +Abelian integrals..." Two constants \f$\delta\f$ and \f$\gamma\f$ +appear in the solution. Typically \f$\delta\f$ is zero if the lower +limits of the integrals are taken to be the starting point of the geodesic +and the direction of the geodesics is determined by \f$\gamma\f$. +However for geodesics that start at an umbilical points, we have \f$\gamma += 0\f$ and \f$\delta\f$ determines the direction at the umbilical point. +Incidentally the constant \f$\gamma\f$ may be expressed as +\f[ +\gamma = (b^2-c^2)\cos^2\beta\sin^2\alpha-(a^2-b^2)\sin^2\omega\cos^2\alpha +\f] +where \f$\alpha\f$ is the angle the geodesic makes with lines of +constant \f$\omega\f$. In the limit \f$a\rightarrow b\f$, this reduces +to \f$\cos\beta\sin\alpha = \text{const.}\f$, the familiar Clairaut +relation. A nice derivation of Jacobi's result is given by Darboux +(1894) +§§583--584 where he gives the solution found by Liouville +(1846) for general quadratic surfaces. In this formulation, the +distance along the geodesic, \f$s\f$, is also found using +\f[ +\begin{aligned} +\frac{ds}{(b^2-c^2)\cos^2\beta + (a^2-b^2)\sin^2\omega} +&= \frac +{\sqrt{b^2\sin^2\beta + c^2\cos^2\beta}\,d\beta} +{\sqrt{a^2 - b^2\sin^2\beta - c^2\cos^2\beta} + \sqrt{(b^2-c^2)\cos^2\beta - \gamma}}\\ +&= \frac +{\sqrt{a^2\sin^2\omega + b^2\cos^2\omega}\,d\omega} +{\sqrt{a^2\sin^2\omega + b^2\cos^2\omega - c^2} + \sqrt{(a^2-b^2)\sin^2\omega + \gamma}} +\end{aligned} +\f] +An alternative expression for the distance is +\f[ +\begin{aligned} +ds +&= \frac +{\sqrt{b^2\sin^2\beta + c^2\cos^2\beta} + \sqrt{(b^2-c^2)\cos^2\beta - \gamma}\,d\beta} +{\sqrt{a^2 - b^2\sin^2\beta - c^2\cos^2\beta}}\\ +&\quad {}+ \frac +{\sqrt{a^2\sin^2\omega + b^2\cos^2\omega} + \sqrt{(a^2-b^2)\sin^2\omega + \gamma}\,d\omega} +{\sqrt{a^2\sin^2\omega + b^2\cos^2\omega - c^2}} +\end{aligned} +\f] + +Jacobi's solution is a convenient way to compute geodesics on an +ellipsoid. Care must be taken with the signs of the square roots (which +are determined by the initial azimuth of the geodesic). Also if +\f$\gamma \gt 0\f$ (resp. \f$\gamma \lt 0\f$), then the \f$\beta\f$ +(resp. \f$\omega\f$) integrand diverges. The integrand can be +transformed into a finite one by a change of variable, e.g., +\f$\sin\beta = \sin\sigma \sqrt{1 - \gamma/(b^2-c^2)}\f$. The resulting +integrals are periodic, so the behavior of an arbitrarily long geodesic +is entirely captured by tabulating the integrals over a single period. + +The situation is more complicated if \f$\gamma = 0\f$ (corresponding to +umbilical geodesics). Both integrands have simple poles at the umbilical +points. However, this behavior may be subtracted from the integrands to +yield (for example) the sum of a term involving +\f$\tanh^{-1}\sin\beta\f$ and a finite integral. Since both integrals +contain similar logarithmic singularities they can be equated (thus +fixing the ratio \f$\cos\beta/\sin\omega\f$ at the umbilical point) and +connection formulas can be found which allow the geodesic to be followed +through the umbilical point. The study of umbilical geodesics was of +special interest to a group of Irish mathematicians in the 1840's and +1850's, including Michael and William Roberts (twins!), Hart, Graves, +and Salmon. + +\section triaxial-survey Survey of triaxial geodesics + +Before delving into the nature of geodesics on a triaxial geodesic, it +is worth reviewing geodesics on an ellipsoid of revolution. There are +two classes of simple closed geodesics (i.e., geodesics which close on +themselves without intersection): the equator and all the meridians. +All other geodesics oscillate between two equal and opposite circles of +latitude; but after completing a full oscillation in latitude these fall +slightly short (for an oblate ellipsoid) of completing a full circuit in +longitude. + +Turning to the triaxial case, we find that there are only 3 simple +closed geodesics, the three principal sections of the ellipsoid given by +\f$x = 0\f$, \f$y = 0\f$, and \f$z = 0\f$. To survey the other +geodesics, it is convenient to consider geodesics which intersect the +middle principal section, \f$y = 0\f$, at right angles. Such geodesics +are shown in Figs. 2--6, where I use the same ellipsoid parameters as in +Fig. 1 and the same viewing direction. In addition, the three principal +ellipses are shown in red in each of these figures. + +If the starting point is \f$\beta_1 \in (-90^\circ, 90^\circ)\f$, +\f$\omega_1 = 0\f$, and \f$\alpha_1 = 90^\circ\f$, then the geodesic +encircles the ellipsoid in a "circumpolar" sense. The geodesic +oscillates north and south of the equator; on each oscillation it +completes slightly less that a full circuit around the ellipsoid +resulting in the geodesic filling the area bounded by the two latitude +lines \f$\beta = \pm \beta_1\f$. Two examples are given in +Figs. 2 and 3. Figure 2 shows practically the same behavior as for an +oblate ellipsoid of revolution (because \f$a \approx b\f$). However, if +the starting point is at a higher latitude (Fig. 3) the distortions +resulting from \f$a \ne b\f$ are evident. + +

\n +Fig. 6: +Example of an umbilical geodesic on a triaxial ellipsoid. The +starting point of this geodesic is \f$\beta_1 = 90^\circ\f$, \f$\omega_1 = +0^\circ\f$, and \f$\alpha_1 = 45^\circ\f$ and the geodesics is followed +forwards and backwards until it lies close to the plane \f$y = 0\f$ in +both directions. + +Umbilical geodesic enjoy several interesting properties. + - Through any point on the ellipsoid, there are two umbilical geodesics. + - The geodesic distance between opposite umbilical points is the same + regardless of the initial direction of the geodesic. + - Whereas the closed geodesics on the ellipses \f$x = 0\f$ and \f$z = + 0\f$ are stable (an geodesic initially close to and nearly parallel to + the ellipse remains close to the ellipse), the closed geodesic on the + ellipse \f$y = 0\f$, which goes through all 4 umbilical points, is \e + unstable. If it is perturbed, it will swing out of the plane \f$y = + 0\f$ and flip around before returning to close to the plane. (This + behavior may repeat depending on the nature of the initial + perturbation.). + +\section triaxial-stab The stability of closed geodesics + +The stability of the three simple closed geodesics can be determined by +examining the properties of Jacobi's solution. In particular the +unstable behavior of umbilical geodesics was shown by Hart (1849). +However an alternative approach is to use the equations that Gauss +(1828) gives for a perturbed geodesic +\f[ +\frac {d^2m}{ds^2} + Km = 0 +\f] +where \f$m\f$ is the distance of perturbed geodesic from a reference +geodesic and \f$K\f$ is the Gaussian curvature of the surface. If the +reference geodesic is closed, then this is a linear homogeneous +differential equation with periodic coefficients. In fact it's a +special case of Hill's equation which can be treated using Floquet +theory, see DLMF, §28.29. +Using the notation of §3 of + Algorithms for +geodesics, the stability is determined by computing the reduced +length \f$m_{12}\f$ and the geodesic scales \f$M_{12}, M_{21}\f$ over +half the perimeter of the ellipse and determining the eigenvalues +\f$\lambda_{1,2}\f$ of +\f[ +{\cal M} = \left(\begin{array}{cc} +M_{12} & m_{12}\\ +-\frac{1 - M_{12}M_{21}}{m_{12}} & M_{21} +\end{array}\right). +\f] +Because \f$\mathrm{det}\,{\cal M} = 1\f$, the eigenvalues are determined +by \f$\mathrm{tr}\,{\cal M}\f$. In particular if +\f$\left|\mathrm{tr}\,{\cal M}\right| < 2\f$, we have +\f$\left|\lambda_{1,2}\right| = 1\f$ and the solution is stable; if +\f$\left|\mathrm{tr}\,{\cal M}\right| > 2\f$, one of +\f$\left|\lambda_{1,2}\right|\f$ is larger than unity and the solution +is (exponentially) unstable. In the transition case, +\f$\left|\mathrm{tr}\,{\cal M}\right| = 2\f$, the solution is stable +provided that the off-diagonal elements of \f${\cal M}\f$ are zero; +otherwise the solution is linearly unstable. + +The exponential instability of the geodesic on the ellipse \f$y = 0\f$ +is confirmed by this analysis and results from the resonance between the +natural frequency of the equation for \f$m\f$ and the driving frequency +when \f$b\f$ lies in \f$(c, a)\f$. If \f$b\f$ is equal to either of the +other axes (and the triaxial ellipsoid degenerates to an ellipsoid of +revolution), then the solution is linearly unstable. (For example, a +geodesic is which is close to a meridian on an oblate ellipsoid, slowly +moves away from that meridian.) + +\section triaxial-inverse The inverse problem + +In order to solve the inverse geodesic problem, it helps to have an +understanding of the properties of all the geodesics emanating from a +single point \f$(\beta_1, \omega_1)\f$. + - If the point is an umbilical point, all the lines meet at the + opposite umbilical point. + - Otherwise, the first envelope of the geodesics is a 4-pointed + astroid. The cusps of the astroid lie on either \f$\beta = - + \beta_1\f$ or \f$\omega = \omega_1 + \pi\f$; see + Sinclair + (2003). + - All geodesics intersect (or, in the case of \f$\alpha_1 = 0\f$ or + \f$\pi\f$, touch) the line \f$\omega = \omega_1 + \pi\f$. + - All geodesics intersect (or, in the case of \f$\alpha_1 = + \pm\pi/2\f$, touch) the line \f$\beta = -\beta_1\f$. + - Two geodesics with azimuths \f$\pm\alpha_1\f$ first intersect on + \f$\omega = \omega_1 + \pi\f$ and their lengths to the point of + intersection are equal. + - Two geodesics with azimuths \f$\alpha_1\f$ and \f$\pi-\alpha_1\f$ + first intersect on \f$\beta = -\beta_1\f$ and their lengths to the + point of intersection are equal. + . +(These assertions follow directly from the equations for the geodesics; +some of them are somewhat surprising given the asymmetries of the +ellipsoid.) Consider now terminating the geodesics from \f$(\beta_1, +\omega_1)\f$ at the point where they first intersect (or touch) the line +\f$\beta = -\beta_1\f$. To focus the discussion, take \f$\beta_1 \le +0\f$. + - The geodesics completely fill the portion of the ellipsoid satisfying + \f$\beta \le -\beta_1\f$. + - None of geodesics intersect any other geodesics. + - Any initial portion of these geodesics is a shortest path. + - Each geodesic intersects the line \f$\beta = \beta_2\f$, where + \f$\beta_1 < \beta_2 < -\beta_1\f$, exactly once. + - For a given \f$\beta_2\f$, this defines a continuous monotonic + mapping of the circle of azimuths \f$\alpha_1\f$ to the circle of + longitudes \f$\omega_2\f$. + - If \f$\beta_2 = \pm \beta_1\f$, then the previous two assertions need + to be modified similarly to the case for an ellipsoid of revolution. + +These properties show that the inverse problem can be solved using +techniques similar to those employed for an ellipsoid of revolution (see +§4 of + Algorithms for +geodesics). + - If the points are opposite umbilical points, an arbitrary + \f$\alpha_1\f$ may be chosen. + - If the points are neighboring umbilical points, the shortest path + lies on the ellipse \f$y = 0\f$. + - If only one point is an umbilicial point, the azimuth at the + non-umbilical point is found using the generalization of Clairaut's + equation (given above) with \f$\gamma = 0\f$. + - If both points lie on the equator \f$\beta = 0\f$, then determine the + reduced length \f$m_{12}\f$ for the geodesic which is the shorter + path along the ellipse \f$z = 0\f$. If \f$m_{12} \ge 0\f$, then this + is the shortest path on the ellipsoid; otherwise proceed to the + general case (next). + - Swap the points, if necessary, so that the first point is the one + closest to a pole. Estimate \f$\alpha_1\f$ (by some means) and solve + the \e hybrid problem, i.e., determine the longitude \f$\omega_2\f$ + corresponding to the first intersection of the geodesic with \f$\beta + = \beta_2\f$. Adjust \f$\alpha_1\f$ so that the value of + \f$\omega_2\f$ matches the given \f$\omega_2\f$ (there is a single + root). If a sufficiently close solution can be found, Newton's + method can be employed since the necessary derivative can be + expressed in terms of the reduced length \f$m_{12}\f$. + +The shortest path found by this method is unique unless: + - The length of the geodesic vanishes \f$s_{12}=0\f$, in which case any + constant can be added to the azimuths. + - The points are opposite umbilical points. In this case, + \f$\alpha_1\f$ can take on any value and \f$\alpha_2\f$ needs to be + adjusted to maintain the value of \f$\tan\alpha_1 / \tan\alpha_2\f$. + - \f$\beta_1 + \beta_2 = 0\f$ and \f$\cos\alpha_1\f$ and + \f$\cos\alpha_2\f$ have opposite signs. In this case, there another + shortest geodesic with azimuths \f$\pi - \alpha_1\f$ and + \f$\pi - \alpha_2\f$. + +

This test set consists of a set of +geographic coordinates together with the corresponding transverse +Mercator coordinates.

+Back to \ref transversemercator. Forward to \ref old. Up to \ref contents. +
+ +The implementation of GeographicLib::Geocentric::Reverse is adapted from + - H. Vermeille, + + Direct transformation from geocentric coordinates to geodetic + coordinates, J. Geodesy 76, 451--454 (2002). + +This provides a closed-form solution but can't directly be applied close to +the center of the earth. Several changes have been made to remove this +restriction and to improve the numerical accuracy. Now the method is +accurate for all inputs (even if \e h is infinite). The changes are +described in Appendix B of + - C. F. F. Karney, + Geodesics + on an ellipsoid of revolution, + Feb. 2011; preprint + arxiv:1102.1215v1. + +The problems encountered near the center of the ellipsoid are: + - There's a potential division by zero in the definition of \e s. The + equations are easily reformulated to avoid this problem. + - t3 may be negative. This is OK; we just take the + real root. + - The solution for \e t may be complex. However this leads to 3 real roots + for u/\e r. It's then just a matter of picking the one that computes + the geodetic result which minimizes |\e h| and which avoids large + round-off errors. + - Some of the equations result in a large loss of accuracy due to + subtracting nearly equal quantities. E.g., \e k= sqrt(\e u + \e v + + w2) − \e w is inaccurate if \e u + \e v is small; + we can fix this by writing \e k = (\e u + \e v)/(sqrt(\e u + \e v + + w2) + \e w). + +The error is computed as follows. Write a version of +Geocentric::WGS84.Forward which uses long doubles (including using long +doubles for the WGS84 parameters). Generate random (long double) +geodetic coordinates (\e lat0, \e lon0, \e h0) and use the "long double" +WGS84.Forward to obtain the corresponding (long double) geocentric +coordinates (\e x0, \e y0, \e z0). [We restrict \e h0 so that +\e h0 ≥ − \e a (1 − e2) / sqrt(1 − +e2 sin2\e lat0), which ensures that (\e +lat0, \e lon0, \e h0) is the principal geodetic inverse of (\e x0, \e +y0, \e z0).] Because the forward calculation is numerically stable and +because long doubles (on Linux systems using g++) provide 11 bits +additional accuracy (about 3.3 decimal digits), we regard this set of +test data as exact. + +Apply the double version of WGS84.Reverse to (\e x0, \e y0, \e z0) to +compute the approximate geodetic coordinates (\e lat1, \e lon1, \e h1). +Convert (\e lat1 − \e lat0, \e lon1 − \e lon0) to a +distance, \e ds, on the surface of the ellipsoid and define \e err = +hypot(\e ds, \e h1 − \e h0). For |\e h0| < 5000 km, we have \e +err < 7 nm (7 nanometers). + +This methodology is not very useful very far from the globe, because the +absolute errors in the approximate geodetic height become large, or +within 50 km of the center of the earth, because of errors in computing +the approximate geodetic latitude. To illustrate the second issue, the +maximum value of \e err for \e h0 < 0 is about 80 mm. The error is +maximum close to the circle given by geocentric coordinates satisfying +hypot(\e x, \e y) = \e a e2 (= 42.7 km), \e z = 0. +(This is the center of meridional curvature for \e lat = 0.) The +geodetic latitude for these points is \e lat = 0. However, if we move 1 +nm towards the center of the earth, the geodetic latitude becomes 0.04", +a distance of 1.4 m from the equator. If, instead, we move 1 nm up, the +geodetic latitude becomes 7.45", a distance of 229 m from the equator. +In light of this, Reverse does quite well in this vicinity. + +To obtain a practical measure of the error for the general case we define +- errh = |\e h1 − \e h0| / max(1, \e h0 / \e a) +- for \e h0 > 0, errout = \e ds +- for \e h0 < 0, apply the long double version of WGS84.Forward to (\e + lat1, \e lon1, \e h1) to give (\e x1, \e y1, \e z1) and compute + errin = hypot(\e x1 − \e x0, \e y1 − \e + y0, \e z1 − \e z0). +. +We then find errh < 8 nm, errout < 4 nm, +and errin < 7 nm. (1 nm = 1 nanometer.) + +The testing has been confined to the WGS84 ellipsoid. The method will work +for all ellipsoids used in terrestrial geodesy. However, the central region, +which leads to multiple real roots for the cubic equation in Reverse, pokes +outside the ellipsoid (at the poles) for ellipsoids with \e e > 1/sqrt(2). +Reverse has not been analyzed for this case. Similarly ellipsoids which are +very nearly spherical near yield inaccurate results due to underflow; in the +other hand, the case of the sphere, \e f = 0, is treated specially and gives +accurate results. + +Other comparable methods are K. M. Borkowski, + Transformation +of geocentric to geodetic coordinates without approximations, +Astrophys. Space Sci. 139, 1--4 (1987) +( erratum) +and T. Fukushima, + Fast transform from +geocentric to geodetic coordinates, J. Geodesy 73, 603--610 (1999). +However the choice of independent variables in these methods leads +to a loss of accuracy for points near the equatorial plane. + +

It allows +.NET developers to access GeographicLib classes within C#, Visual +Basic, Managed C++, and other Microsoft .NET languages. + +NETGeographicLib is written in Managed C++. It IS NOT a reimplementation +of the GeographicLib software. It is a container that provides interfaces +to the GeographicLib classes. GeographicLib and NETGeographicLib is an +integrated product. + +The NETGeographic project in the GeographicLib-vc10.sln file located in +\/GeographicLib-1.34/windows will create the NETGeographicLib +DLL. The source code for NETGeographicLib is located in +\/GeographicLib-1.34/dotnet/NETGeographicLib. NETGeographicLib +is not available for older versions of Microsoft Visual Studio. + +NETGeographicLib has been tested with C#, Managed C++, and Visual Basic. +Sample code snippets can be found in +\/GeographicLib-1.34/dotnet/examples. + +\section differences Differences between NETGeographicLib and GeographicLib + +The NETGeographicLib class names are identical to the GeographicLib class names. +All NETGeographicLib classes are in the NETGeographicLib namespace. + +NETGeographicLib exposes most of the GeographicLib classes. The exceptions +are SphericalEngine, GeographicLib::Math, and GeographicLib::Utility. The +SphericalEngine class is a template class which (according to the comments in +the SphericalEngine.h file) is not usually accessible to developers. The +GeographicLib::Math class contains several specialized functions required by +GeographicLib classes. They have limited use outside GeographicLib. This class +may be exposed in a future release if there is demand for it. The functions +provided by GeographicLib::Utility duplicate functions provided by existing .NET +controls (DateTime). + +The SphericalCoefficients class replaces the SphericalEngine::coeff class. + +The NETGeographicLib class function interfaces are similar, and in many cases, +identical to the GeographicLib interfaces. There are differences because of +limitations in .NET and other differences that are discretionary. The comments +in the header files contain a section labeled "INTERFACE DIFFERENCES" that detail +the differences between the NETGeographicLib interfaces and the GeographicLib +interfaces. The differences are summarized in the text that follows. + +Default values for function parameters are not supported in .NET. + +Several GeographicLib class functions accept or return a "capabilities mask" as +an unsigned integer. The NETGeographicLib classes accept and return the capabilities +mask as an enumeration. + +The Geocentric and LocalCartesian classes have functions that return a rotation matrix. +The NETGeographicLib versions return a two-dimensional, 3 × 3 array rather than a vector. + +A lot of GeographicLib classes have inspector functions (MajorRadius, +Flattening, etc.). These inspector functions are implemented as +properties in NETGeographicLib. + +NETGeographicLib classes do not implement constructors that create "uninitialized" objects. + +Many NETGeographicLib classes implement a default constructor that assumes WGS84 parameters. + +Several GeographicLib classes implement the () operator. NETGeographicLib classes +replace the () operator with a specific function. Managed C++ allows developers to +overload the () operator; however, the () operator is not 'elegantly' supported in +other .NET languages. For example, if the () operator was implemented in the +NETGeographicLib::Geoid class, then C# code would look like +\code +Geoid geoid = new Geoid(); +double h = geoid.op_FuncCall(latitude,longitude); // if () operator was implemented. +h = geoid.Height(latitude,longitude); // with () operator replaced with Height +\endcode +The author felt that the op_FuncCall syntax did not appropriately define the purpose +of the function call. + +.NET does not allow developers to overload the assignment operators (=,+=,-=,*=). +These operators have been replaced with functions in the NETGeographicLib::Accumulator class. + +\section library Using NETGeographicLib in a .NET Application + +If you have access to the NETGeographicLib and GeographicLib projects then +-# Create a new solution. +-# Create a new project using any .NET language. For this example, call it MyApp. +-# Add the NETGeographic and Geographic projects to the solution. Verify that NETGeographicLib depends upon GeographicLib. +-# Right-Click MyApp in the Solution View and select "Add Reference..." (C#/VB) or "References..." (Managed C++) in the pop-up menu. +-# (Managed C++) Click the "Add New Reference..." button in the Properties dialog. +\image html NETGeographicLib3.png +-# Click the Projects Tab and select NETGeographic. + \image html NETGeographicLib1.png +-# Click OK. + +If you only have access to the NETGeographic.dll then +-# Create a new solution. +-# Create a new project using any .NET language. For this example, call it MyApp. +-# Right-Click MyApp in the Solution View and select "Add Reference..." in the popup menu. +-# Right-Click MyApp in the Solution View and select "Add Reference..." (C#/VB) or "References..." (Managed C++) in the pop-up menu. +-# (Managed C++) Click the "Add New Reference..." button in the Properties dialog. +\image html NETGeographicLib3.png +-# Click the Browse Tab and navigate to the folder containing NETGeographic.dll. +\image html NETGeographicLib2.png +-# Select NETGeographic.dll and click OK. + +The MyApp project will have access to all public NETGeographicLib classes after the +NETGeographic reference is added to MyApp. + +C# developers should add +\code using NETGeographicLib; \endcode +to any C# source file that uses NETGeographicLib. + +Managed C++ developers should add +\code using namespace NETGeographicLib; \endcode +to any C++ source that uses NETGeographicLib classes. + +Visual Basic developers should add +\code Imports NETGeographicLib \endcode +to any Visual Basic source that uses NETGeographicLib classes. + +\section sample C# Sample Application + +A C# sample application is provided that demonstrates NETGeographicLib classes. +The source code for the sample application is located in +\/GeographicLib-1.34/dotnet/Projections. The sample +application creates a tabbed dialog. Each tab provides data entry fields that +allow the user to exercise one or more NETGeographicLib classes. + +The following table lists the source code that demonstrates specific classes. +

+ +\section netcmake Using cmake to build a Managed C++ Application + +The following assumes that you have installed %GeographicLib in one of +two ways: +- you have built and installed %GeographicLib using cmake with + -D BUILD_NETGEOGRAPHICLIB=ON (see + \ref cmake "Installation with cmake" in the %GeographicLib + documentation). You can use any version of Visual Studio to build + %GeographicLib and should use the same version to build your + application. You can build %GeographicLib as a shared library using + -D GEOGRAPHICLIB_LIB_TYPE=SHARED or BOTH. +- you have installed %GeographicLib using one of the binary installers (see + \ref windowsbin "Using a binary installer for Windows" in the + %GeographicLib documentation). In this case, you are restricted to using + Visual Studio 10. + +The minimum recommended version of cmake for use with NETGeographicLib +is 2.8.7. In order to build an application that uses NETGeographicLib +with cmake, ask for the NETGeographicLib "component" of %GeographicLib +using \verbatim +find_package(GeographicLib COMPONENTS NETGeographicLib) \endverbatim +If NETGeographicLib is found, then +GeographicLib_NETGeographicLib_FOUND will be set to true and +GeographicLib_NETGeographicLib_LIBRARIES will be set to the +NETGeographic shared library. This is the name of the cmake target from +which the pathname of the dll can be obtained. + +Here is a very simple test code, which uses the +NETGeographicLib::Geodesic class: +\include example-Geodesic-small.cpp +This example is +dotnet/examples/ManagedCPP/example-Geodesic-small.cpp. + +Here is a complete CMakeList.txt files you can use to build this test +code using the installed library: \verbatim +project (geodesictest) +cmake_minimum_required (VERSION 2.8.7) # required for VS_DOTNET_REFERENCES + +find_package (GeographicLib 1.34 REQUIRED COMPONENTS NETGeographicLib) + +add_executable (${PROJECT_NAME} example-Geodesic-small.cpp) +set_target_properties (${PROJECT_NAME} PROPERTIES COMPILE_FLAGS "/clr") +string (REPLACE "/RTC1" "" CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG}") +string (REPLACE "/EHsc" "" CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS}") + +# This is set up for Release builds only.
