Open Source GPS Software

A Tcl Package to read and write Shapefiles

miniHomer is a GPS tracker based on a skyTraq GPS chip. This tools helps you to manage the device if you use Linux as your favourite Operating System. As the tool is written in QT/jquey/HTML/javascript, there is a good change that it will run on other OSes. Version 1.0 should be good enough to be offered to the public Please see the files section for RPM packages

Experimental GPS navigation application for ultralight aircrafts, using as hardware a vehicular and inexpensive TomTom navigator. The program, given a GPX flight plan, is able to provide navigation indications using an HSI along the route up to the final destination.

Convert user-saved tracks from GPS-Tracks for iPhone to KML files for Google Earth. The GPS-Tracks iPhone application is available from the App Store or from http://www.gps-tracks.com . It can save recorded GPS tracks to the iPhone storage. This little Java applet provides the functionality to convert these saved tracks to KML files, for use with Google earth. Under Windows, it uses the synced files from the iTunes phone files backup, and extracts the tracks from there. Under Linux, it uses the virtual file system provided by libgpod (which provides an iPhone-gvfs-bridge) and gvfs-fuse (which offers gvfs virtual filesystems as Linux FUSE filesystems). Please note that this app is rather rudimentary. If you run into problems, please open a ticket to describe the issue; time permitting, I'll try to fix it.

Substitutes the missing GPS information in Garmin TCX files when devices lacking a GPS receiver are used to collect training data (Garmin FR 60, heartrate and pedometer only). GpxTcxWelder integrates GPS info from a GPX v1.1 files into TCX files

Converts files from Garmin(R)'s IMG file format to GMAPI file format.

Java Marine API is an NMEA 0183 library for Java. For furher info and latest source code, see project's Github pages. http://github.com/ktuukkan/marine-api/

Convert a "line string" from a .kml file to a "route" in another .kml file. I started this project to use google maps for routing at home and a very simple GPS-device for following the route while on the road.

LoroDux is planned to be a OSM and Java based multi platform navigation software for mobile devices for blind and visually impaired persons. Release of first alpha version was September 10, 2010. http://wiki.openstreetmap.org/wiki/LoroDux

VALARI is a Virtual Announced Launch And Recovery Informant for Mac OSX for GPS & Telemetry tracking of modern high power rocketry. Eventually we might port this to other OSes.

This is a .Net implementation of the Whitestone Interactive GPS Software (WIGS). The previous version was written in Java and can be found here: http://wigs.sourceforge.net/

fGPS is a code system that provides both latitude and longitude in a simple alfanumeric system that is easier to input in GPS devices, and easier to provide by phone or sms than standard coordinate systems.

Gpx2avi is Java-program which overlays GPS-data from .gpx-file to video file.

gpx2gpx tries to convert gpx-input in a format more or less similar to gpx1.1

Converts kml files (Google Earth) to wpt format (OziExplorer waypoint file). Written in Python, thus you'll need a Python interpreter to run the soft.

The aim of this project is to create a full utility suite for NMEA protocols (best known from GPS devices). First goal is a full implemenation of the NMEA 0183 protocol 3.0 (without proprietary extensions). The library provides parsers for NMEA sentences, gpsd-like network daemons and data generators for simulation and testing. This allows advanced sensor handling from cellphones/tablets/laptops with GPS up to vehicles/ships with NMEA sensors on board.
