I'm using a Garmin eTrex Legend to create tracks of my hikes. I've only been using it a couple of weeks but I love it. Combine the track files from the GSPR with Delorme Topo 4 and I can create cool maps showing my hike along with hike stats.
Anyway, after I got home from a hike today I noticed that the trip distance on the GPSR was 9.38 miles while the distance in Topo (calculating the Profile for my imported tracks) came out to 10.36 miles.
There were quite a few blackout periods when the GSPR didn't have a clear view of the sky, I'm thinking that could be part of the problem?
So, which distance do you think would be the most accurate and why?
