meaning altitude correction rounding radius

[ut]

He,
I am very satisfied user of oruxmaps but I have some doubts in correcting the altitude of the recorded track: in the choice of the rounding filter what do the numbers 1 2 4 8 16 mean? it is called a rounding radius, but of what?

Which is the best fix between these and choosing to use DEM files?


Thanks to those who can help me understand and sorry for my poor English ...

The app calculates a moving average. It is the number of points that are taken into account. The more points used, the more the curve smooths.
