GeographicLib is a small set of C++ classes for converting between geographic, UTM, UPS, MGRS, and geocentric coordinates, for gravity (e.g., EGM2008), geoid, and geomagnetic field (e.g., WMM2010) calculations, and for solving geodesic problems. For documentation, visit https://geographiclib.sf.io
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, 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+2 toolkit.
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.
Multiplatform Ham Radio APRS and Mapping Program
NOTE: Code commits are FROZEN on SourceForge: New code is now at <http://github.com/Xastir/Xastir>. 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.

** This site is of historical interest only. The project is active on www.gpsbabel.org and github. Some of the county/state files remain active, but no version of GPSBabel should be downloaded from this site. ** GPSBabel reads, writes, and manipulates GPS waypoints in a variety of formats. Over 100 supported formats include GPX, Magellan and Garmin serial and USB protocols, Geocaching *.loc, Garmin Mapsource, and Magellan Mapsend. For Windows, Linux, Mac.
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.
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.
Extensible NMEA-0183 (GPS) data parser in standard C. A directly linkable library intended for applications that want to embed GPS support.
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.
NITRO has moved! Please visit us at https://github.com/mdaus/nitro for the latest code (SourceForge is now several years out of date) and to post any bugs or questions. NITRO is a full-fledged, extensible library solution for reading and writing the National Imagery Transmission Format (NITF), a U.S. DoD standard format. It is written in cross-platform C, with bindings available for other languages.

Geodesy based library (geodetic and geocentric functions)
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 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.
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.
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/
