Wrong elevation gain computation in planner

Hello,


It often happens that the elevation gain computed by the planner is significantly overestimated. The same track saved and opened in the app outputs a more reasonable elevation gain.

For example, this track:


https://web.locusmap.app/en/?shared_track=NjVjNTNjZWUtNWUxOS00ODIxLWE0MDgtN2YwNmMxOWM1MTAzOjI5ZmY2ODhlLTUwZDgtNDk4Ni1hOTAxLTRmZjYyYzRhYjc4Nw..


Gives 1962 m of elevation gain in the planner and 1614 m in the app.

This is true and still an issue which should be improved. In contrast to the app, Web Planner is not applying an attenuation filter to smooth virtual vertical zig-zags of the track. Just by applying such a filter, elevation gain will get realistic values

Btw: there are already threads to the same issue:
