Hi, how can I compute the length of a track or track-segment (= distance travelled) from a GPX-file I generated with Maemo-Mapper, the Nokia770's GPS-Mapper? Do you know a free web service or linux software, to which I can input my GPX-file and which then outputs the length of the track or track segments? regards, Armin. P.S.: I attached a sample Maemo-Mapper generated GPX-File. -- --- May the Source be with you!
