Distance in track details 2D?

Hey,

I was wondering if LOCUS calculates the 2D distance of a track or the 3D distance which includes the altitude. For example: If you walk at a sharp gradient for one meter horizontal by "climbing" one meter altitude, you have to walk root 2 meters (1,41m). Does LOCUS display for that example a distance of 1m or 1,41m?

An easy way to get the real walked diatance is to calculate the hypotenuse of a rectangular triangle by using the 2D distance of the GPS-track (length of the line) as one side and the whole altitude on the other side.

Thank you!

Hi,

Locus adds horizontal distance when measuring distance during track recording. The deviation from the "3D" measurement you propose is marginal. We made a quick test with a track recorded in Swiss Alps -15,6 km distance, 1400 m positive and 1400 m negative elevation gain. Deviation from 3D measurement is 200m distance which is 1,2%. I discussed it with Locus developer and he considers this solution a mere mathematical complication with close-to-zero effect.

Thank you! Thats totally true.
