[OSM-talk] mapping resolution

[Christoph Eckert]

Hi,

welcome :) .

We usually use the highest available, which usually is 1/sec on the Garmins.

That's the normal aberration.

> Is there a way to merge these tracks?

For uploading leave it as it is. For mapping just draw the way in the middle 
of the two tracks.

> Is it a matter of the selected resolution?

No.

HTH & best regards,
