there is also a gpsbabel filter that will break track lines. In the following I split a track into multiple segments when the jump between points > 100m. (FWIW I got an identical split with a 50m threshold) gpsbabel -i gpx -f transit-20080312-coastalotago.gpx \ -x track,sdistance=0.1k \ -o gpx -F transit-20080312-coastalotago_split.gpx Beware that gpsbabel relies on GPX fixes having good timestamps, it uses the time as the key. http://groups.google.com/group/nzopengis/browse_thread/thread/66d2cf3f0cbab08f/b08c58abad21d952?lnk=gst&q=gpsbabel#b08c58abad21d952 Hamish _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
