Discussion: GPS Data

What are you seeing in this data discrepancy? Is it just happening in the Redwoods?

Armstrong is a tough place to get GPS signals.

You can see my track. Running the same loop several times, but the tracks are all different and the given distances are different, even though what I ran each time was identical to all the other times. There are places where I was in the exact same place twice and the gps tracks show points 40m apart.
