GPX - GPS Exchange Format. GPX (the GPS Exchange Format) is a light-weight XML data format for the interchange of GPS data (waypoints, routes, and tracks) between applications and Web services on the Internet. OGR has support for GPX reading (if GDAL is build with expat library support) and writing.
Two reasons to choose GPX file: 1  You have a GPS unit that doesnât read TCX files. The eTrex, Oregon, Montana, and GPSmap series do not read TCX.  You donât care about riding a certain speed, and you donât need the basic turn guidance offered by the TCX.
