[OSM-talk] GPS Accuracy under Forest Canopy

[Mike N.]

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?
