Hi,



I recorded 2 hiking tracks on offline maps with OruxMaps.

In both cases total ascents are more than 1 half undervalued ! (200 m instead of 400 m for example).

What's up ?

Hi,



It is a value very difficult to calculate;



If you send me a gpx with a file, I can see where is the problem,

Thank you for your answer.

Here's two .gpx files recorded with OruxMaps.

In the first track, given total ascent is 645 m (real is close to 900 m).

In the second, given total ascent is 193 m (real is close to 400 m).

Hello;



why do you see that real value (1st track) is near 900m? Have you uploaded that track to another app/website to test those values?

Hello,



The 900 m total ascent comes from an outdoor Garmin GPS (and from the corresponding software BaseCamp) and is very close to total ascent estimated from a paper map.
