Free gpsbabel software for linux

GPSBabel converts waypoints, tracks, and routes between popular GPS receivers and mapping programs. It also has powerful manipulation tools for such data.
By flattening the Tower of Babel that the authors of various programs for manipulating GPS data have imposed upon us, it returns to us the ability to freely move our own waypoint data between the programs and hardware we choose to use.
It contains extensive data manipulation abilities making it a convenient for server-side processing or as the backend for other tools.
This application does not convert, transfer, send, or manipulate maps. We process data that may (or may not be) placed on a map, such as waypoints, tracks, and routes.

- Rebuilt OS/X version with newer libusb to correct Garmin USB problem on 10.4.10.

GMap is a Map editor for GPS maps that runs on linux. This project is a work in progress. GMap reads various formats and writes .mp polish map format files suitable for compiling using the cgpsmapper compiler.
I also have some notes relating to the use of GPS tools on Linux and the use of cGPSmapper on Linux and M$-Windows.
Currently the development is at an alpha stage. However it is starting to provide some basic funtionality so there is a copy here for anyone that wants to play.
Note that this is the only doc there is at the moment, it is incomplete and may also be slightly out of sync with the uploaded executable.
Main features:
- Display tracks and area (POLYLINE/POLYGON) features.
- Some POI support
- Editing of track and area features.
- Limited UNDO, currently should handle add, delete and move points. Split tracks. Convert a track to an area feature. Dont rely on it. Save often.
- Read and write data data to Polish format map data files. These are suitable for feeding to the cGPSmapper map compiler.
- Read tracks and waypoints from ".gpx" files (from gpsbabel or mapsource uploads)
- Read Tracks and points from google earth ".kml" files (not .kmz)
- Saves to named file or first input file. Original input is renamed to oldname;version (eg gmap fred.mp -> save renames to fred.mp;1 etc)
- Holds 2 sets of map data, one as a reference which is not written out. You can merge as many files as you like on read.
- Some handling of things with holes.
- Map warping. Allows you to warp one set of map data so it aligns correctly with another set of data. Example being to fix data estimated from images or maps against correct ground tracks.
- Knows something about the world being curved.
- Can read tracks, waypoints and current position from my garmin GPSMap 60CSx and a ForeRunner301

Le Petit Poucet is free software to display and edit GPS routes and tracks in a 3D scene. The aim of Le Petit Poucet is to build the scene around the GPS data and 2D maps or 3D terrain models.
Apart from being techies, we are outdoor sport lovers and want to prepare our outings and show them to our friends and families. We hope you will find Le Petit Poucet useful. The objective statement being laid, here is the reality and roadmap.
Current version is a pre-alpha version numbered 0.0.2, it is dedicated to David Thompson a great explorer of western Canada. He is been surveying the wild land for 28 years and he is the first person to complete a survey of the Columbia River.
Le Petit Poucet is now able to read a lot of GPS file formats and to connect to the GPS receivers thanks to GPSBabel. It is also able to mix coordinate systems in projected or earth centric referentials.
Currently. Le Petit Poucet is called from the terminal, see command line manual or type the -h or --help option to get the command line usage. We hope to provide quickly a graphical user interface. The program has been compiled and run on Linux (Intel) and Mac Os X (v 10.3), it should work on many other platforms as the core libraries (Open Scene Graph, GPSBabel and GDAL) are portable.
Main features:
Main features
- Loading of tracks or routes, independent waypoints and maps or terrain models and display them on a 3D scene.
- Support of many GPS data file formats through GPSBabel or custom parsers.
- Download GPS receiver data via Serial or USB port.
- 3D navigation based on continuous zoom, swivel and pan with excellent real time anti-aliasing.
- Mixing of several coordinate systems (e.g.: geocentric and projected, UTM and Lambert).
- Coordinate system selection from command line.
Tracks
- Tracks are shown as a set of track segments. Track segments are sets of waypoints connected with a line.
- Track segments are not connected but share the same color and input coordinate system.
- Multiple tracks are shown in a viewer, track color is automatically chosen to visually distinguish tracks.
Waypoints
- Waypoints are displayed as a 3D symbol plus a text in case of named waypoint.
- Name text is automatically oriented toward screen and font size is adjusted dynamically too.
- Text color is selected from command line
- Waypoint information (location, elevation and time) is displayed in a head up display (HUD) when mouse flies over the point.
- Waypoint symbol is loaded from file
- Feature points, i.e. point out of a track, are selected. Are shown only the ones that are in the area of the displayed maps and tracks.
Maps
- 2D Maps are displayed in 3D perspective with box subtrat.PC
- Map loading is currently only supported for the Carte Sur Table file format.
- Map elevation in the 3D scene is computed based on the minimum elevation of the loaded tracks to reduce perspective effects.
- For tracks without maps a box is displayed below the track to improve perspective.
- In the current version, loading of 3D terrain model is through Open Scene Graph (OSG). Models must be projected and optimized using OSG utilities like osgdem see Loading Blue Marble.
Enhancements:
- All the features of release 0.0.5 are now accessible from menus and dialog boxes.
- A graphical user interface is used to wrap the main functionality of the track viewer in 3D, such as opening and closing files; focusing and zooming on tracks, waypoints, or segments; and generating terrains from downloaded or local imagery.
