Hi Ed, You don't get a cluster of gps points where you stop for a moment? Consider collecting points at 1/second, rather than using a "smart" setting like "point every n meters". The smart setting might save some memory space on the device, but the improved context of the extra points can be helpful. josm will color-code your gpx trace by velocity. >> Edit >> Preferences >> GPS Points Tab >> Track and Point Coloring section >> >> Velocity Radio button See? Easy? ;-) I'm not sure if potlatch or P2 have a similar feature.
