Open Source C Mapping Software

GeographicLib is a small C++ library for: geodesic and rhumb line calculations; conversions between geographic, UTM, UPS, MGRS, geocentric, and local cartesian coordinates; gravity (e.g., EGM2008) and geomagnetic field (e.g., WMM2020) calculations.

Viking is a free/open source program to manage GPS data. You can import, plot and create tracks, routes and waypoints, show OSM, Bing Aerial and other maps, geotag images, create routes using OSRM, see real-time GPS position (not in Windows), make maps using Mapnik (not in Windows), control items, etc. It is written in mostly in C (with some C++) & the GTK+3 toolkit. Viking is currently dual managed - with a corresponding Github presence at: https://github.com/viking-gps/viking Where you may find it easier to view the code and raise issues there too.

Modular, touch screen friendly navigation system with GPS tracking, realtime routing engine and support for various vector map formats. Works on a wide range of devices, from computers to smartphones.

EPSILON is a powerful Open Source wavelet image compressor. The project is aimed on parallel and robust image processing.

NOTE: Code commits were FROZEN on SourceForge in July of 2016, and the project no longer uses sourceforge. All new code is now at <http://github.com/Xastir/Xastir>. The version you can download here has been obsolete for over 10 years, and other than by deleting the project entirely we can't disable the "Download Now" button. Don't download from here. Go to github. Real-time tracking & messaging of stations via radio/internet APRS data streams, w/125 map formats supported. Linux/FreeBSD/Solaris/MacOSX/Windows in any of 7 languages. Can also be used for mobile mapping w/GPS. MAILING LISTS ARE AT: PROJECT->WEB SITE.

A bike information system for cyclists in Berlin and Brandenburg (Germany) with a map view and a routing engine. There's a graphical interface (based on Perl/Tk) as well as an Web interface. Source code may be found at Github: https://github.com/eserte/bbbike/

Extensible NMEA-0183 (GPS) data parser in standard C. A directly linkable library intended for applications that want to embed GPS support.

The SELENA and RISe software tools are two packages to assist in computing earthquake damage scenarios. The damage probability for any specific structure follows the computation principles of HAZUS.

A Tcl Package to read and write Shapefiles

C translation of EGM96 (earth height model) implementation (namely, f477.f) available at http://earth-info.nga.mil/GandG/wgs84/gravitymod/egm96/egm96.html

Gpsdrive is a car (bike, ship, plane) navigation system. Displaying your position on a map and a lot of other functions are implemented. It works with vector maps from http://www.OpenStreetMap.de/

To use precompiled wheels: 1) go to releases (Files) and download tarball needed; 2) install it with command: python3 -m pip install /path/to/wheel.whl Or simply use URL in pip: python3 -m pip install https://sourceforge.net/projects/gdal-wheels-for-linux/files/GDAL-3.1.4-cp37-cp37m-manylinux_2_5_x86_64.manylinux1_x86_64.whl/download URL may be found under "View details" button (i) To use GDAL in C/C++ project you need to link gdal lib AND all libs located at dir GDAL.libs (usually this folder resides inside python site-packages) To compile your own wheels see information given at forefather project: https://github.com/youngpm/gdalmanylinux Usually this is done via command `make wheels` GDAL wheels for Windows are provided by Christoph Gohlke at https://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal Built with PROJ (proj.db is included), GEOS, EXPAT. See Dockerfile.wheels for additional components.

OpenDMTP is a protocol/framework that allows communications with small devices (mobile phones, PDA's, and other high-latency/low-bandwidth devices), especially geared towards the transmission of GPS, temperature, and other remote monitoring information.

RTKLIB is an open source program package for standard and precise positioning with GNSS (global navigation satellite system). RTKLIB consists of a portable program library and several APs (application programs) utilizing the library. This port includes only a library (.so or .dll) for the C/C++ language and a .dll for C#/.NET Framework. RTKSharp is compatible with Windows and Linux using the .NET/Mono Assembly withoout the need of recompilation/cross-building.

A navigation system that displays street maps and tracks a vehicle using GPS. Specific locations can be selected by street address. Routes and tracks can be created, edited, and saved in GPX format. Runs on most POSIX systems, the iPAQ, and the Zaurus.

Two dimensional (2D) fine mesh finite element (FE) grid editing system. Includes constrained Delaunay triangulation, and automated grid resolution changes based on local attributes. Win32 and Motif GUIs. Mature application, now going open source.

PIHMgis is a “tightly-coupled” GIS interface to Penn State Integrated Hydrologic Model (PIHM). It is open source, platform independent and extensible. The “tightly-coupled” integrated GIS interface to PIHM has been created in the Open Source QGIS

GIMED is a metadata editor for geospatial data. It is focused on providing compliant metadata with the ISO19139 standard and INSPIRE directive.

A terrain and RF path analysis application for Linux/Unix

Mkmap is a map maker by downloading map tiles from online map services, like google maps, and combining into a single large picture file. It accepts the latitude and longitude coordinates, then downloads and merges map tiles. The idea of mkmap is to generate a larger map than the size of a browser screen. So the map could be easily printed or viewed in an off-line device. Mkmap supports Linux and Windows platform.

GNU AIS is software for demodulating and decoding Automatic Identification System messages used by ships to navigate. You will need a VHF receiver with discriminator output to get it to work.

A C library for reading and writing BSB format image files. Typically used for nautical charts, BSB image files use the .KAP extension and store cartographic information in addition to a run-length encoded raster image. Includes bsb2tif & tif2bsb tools.
