GPSBabel - Convert GPS Data

GPSBabel - convert, upload, download data from GPS and Map programs

GPSBabel is a very handy oolkit (free/open source) for working with the multitude of GIS datasets floating around. It mainly converts between the various GPS unit formats (not to/from ESRI shapefiles).

"GPSBabel converts waypoints, tracks, and routes from one format to another, whether that format is a common mapping format like Delorme, Streets and Trips, or even a serial upload or download to a GPS unit such as those from Garmin and Magellan. 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."
