Convert a GPS file with GPS Babel
GPSBabel is a freeware program that converts GPS data from one format to another. You can download it and run it on almost any computer, but its command-line interface requires some getting used to -- so I've created this on-line gateway that lets you access a copy of gpsbabel running on GPSVisualizer.com. Of course, you can't use this page to communicate with your GPS receiver -- and a few of GPSBabel's more advanced options (filters and custom XCSV files) aren't included.
NOTE: For many input formats -- including GPX, OziExplorer, Geocaching.com LOC, Garmin Forerunner, Cetus GPS, IGC, and more (including some that GPSBabel can't read, like NetStumbler binary files) -- you can also convert your GPS files to plain text, GPX, or Google Earth KML with
