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.

A Tcl Package to read and write Shapefiles

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.

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.

MicroCity is a framework for spatial analysis and simulation. It is lightweight, fast, portable, extendable and user friendly. Users can easily operate large GIS and Grid data and perform Spatial, Fractal, Network analysis and simulation.

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 terrain and RF path analysis application for Linux/Unix

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/

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.

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.

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/

This is the project to create a GPS car navigator. This is something more than a typical "moving map" that you can do with Ozi, fmaps, Gnomad and others. The project aim is made route calculation, but not in a static way, as is doing by some web sites

PIHM is a multiprocess, multi-scale hydrologic model where the major hydrological processes are fully coupled using the semi-discrete finite volume method.

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

stratiGrapher: drawing stratigraphic section/column in PostScript

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.

APRS World is comprised of an Automatic Packet Reporting System (APRS) parser and a web interface. The parser connects to an APRS feed and inserts packets into a MySQL database. The web interface provides a convenient means of retrieving this data. This

An ArcView 3.x extension for upload/download to/from PostGIS tables. Supports PostGIS theme queries.

The BEAM project has moved away from SourceForge.net to a dedicated web site at http://envisat.esa.int/beam

Beam and it's follow-on I-Beam are sets of programs to produce coverage charts of radio sources. It has been used for RADAR, DME, VOR and various communications sources specific to aviation. However, it is also valid for cell phone, TV and radio towers

CAVOR is an engine for building apps that involve both graphic and text/numeric data. Primarily GIS is the initial focus, but consider also CAD, CASE, project management (eg PERT charts), and others. Built-in scripting, C API, also supports Tcl and Java.
