Open Source C GIS 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.

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.

A set of extensions to Tcl/Tk for reading, manipulating, and displaying geographic and cartographic data. It can serve as a starting point for development of new GIS and cartography applications.

The GPSD project has moved to Savannah in advance of Berlios's planned shutdown.

Xconq is an engine for turn-based strategy games. Variety of game genres run under Xconq: historical, sci-fi, fantasy, and modern. AIs. Network games. Multiple UIs and platforms. Easy-to-learn game design language. Large games library available

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/

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.

Global Land Use and technological Evolution Simulator.

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.

geoStarsLib has functions for dealing with many geodesy-based problems found in positioning, pointing, and surveying situations. It is useful to determine absolute position on the earth, pointing vectors, coordinate transformations, and other functions.

A terrain and RF path analysis application for Linux/Unix

topography oriented GIS for cadastre maintenance fully configurable and totally autonomous (can be transfered to USB key) .

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

PAGC is a command line and web service C library for performing postal address geocoding. A postal address geocoder takes a sufficiently detailed postal addresses and produces a digital map that displays the spatial location of those addresses.

The Geocanvas project aims to provide a very small and simple set of APIs to assist the developer in creating geographically referenced canvas applications within the GTK/Gnome environment.

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/

A Tcl Package to read and write Shapefiles

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.

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.

ZMapServer is a Zope Product that provides a clean interface to the MapServer (http://mapserver.gis.umn.edu) web mapping application.

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.
