I'm using netbook with just your average $30 GPS dongle to collect data. Today I took a 5 mile out-and back hike under dense forest canopy. The GPX traces for the same trail out and back are separated by as much as 100 meters.
I didn't record PDOP information and such, but are there any solutions to record decent GPS traces on trails under forest canopy data collection other than a high end professional GPS datalogger? _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
