Distance on recorded tracks seems inaccurate
« on: June 06, 2011, 17:16:33 »
I've noticed that when I check the information screen on a track that I am currently recording while hiking (or one that I have completed recording) the distance is about 10 to 15% lower than my Garmin GPS watch shows. There didn't seem to be that much of a difference when I first started using Locus Pro but I'm not sure when it changed, at least a couple of weeks ago.

This is the opposite of my experience with My Tracks which always reported a higher figure for distance. I haven't checked My Tracks in a while.

So, I wonder if other people are experiencing the same thing and whether it can be adjusted.

Thanks for any feedback.

I just exported a few in kml format and checked them in Google Earth. The distances are, Google vs Locus:

2.72 miles vs. 2.7 miles
1.59 miles vs. 1.6 miles
4.75 miles vs. 4.8 miles
4.24 miles vs. 4.3 miles

The first three are recorded, the last one is calculated.

So if Locus is wrong, so is Google.

Sorry. Typo! That's what happens with copy-and-paste and not enough attention :)  I fixed it.
