Habe es korrigiert.

As the region is in Germany, I started a new discussion in the German section of the forum.

I think there still is a problem here. The same tag usually used for macromapping is used for excessive micromapping.
To me, a stone tower with a few meters in diameter is not the same as a 200m cliff side. But with this tagging they are indistinguishable and mess up all topomaps.

The Micromapping should use a different tag or an additional marker, so it can be filtered. This excessive micromapping does not give map creators anything to work with.

I have now received an answer from some local people I contacted. The bridleways in the "Bürgerwald" are real and offically designated. By removing them you did damage the data.
Please restore the original tagging yourself within one week, otherwise I will revert them.

Unfortunaelty there were no more responses to these comments. If no reason for the changes is provided here, I will revert all bridleways to their original state in about a week.

Bridleways are legally dedicated to horses. You cannot simply change them to footways which are prohibited for horses. That is plain wrong if there is no change of usage indicated by a sign locally.
Please change back to original tagging immediately!

First, we do not map contour lines like that in OSM data - they are calculated from elevation models.

Second, a contour line with a supposed elevation of 770 meters above sea level right in the sea is definitely wrong.

Therefore I concluded that this must be a joke.

- Start iD without coordinates
- press "zoom in to edit" and you're there

So both editors have the problem.

Check the history! That tag was not changed in this changeset.
