My Garmin GPS and Mapsource indicate the trail distance as 7.2 miles, but wikiloc indicates the trail distance as 7.65 miles.
Is it because the wikiloc takes into the consideration of the elevation (z) rather than just surface distance (x, y)?
Thanks

I read somewhere that Wikiloc calculates the trail distance considering elevation gains determined from the GPS coords (if the height info is there) or by interpolating x,y points on a geoid approximation of the surface of the Earth (whatever it means)
