Da meine Mails an josm-dev irgendwie im Nirwana verschwinden, leite ich das einfach mal hierher weiter. Die aktivsten JOSM-Entwickler kommen ja AFAIK aus Deutschland.

Hi!



From a quick scan over Map Features, I'd propose the following groups:

Group "Physical":
highway=*
waterway=*
railway=*
aeroway=*
aerialway=*
power=*
man_made=*
leisure=*
amenity=*
shop=*
tourism=*
historic=*
military=*

Group "Classification":
landuse=*
natural=*
sport=*
abutters=*

Single-Member groups:
route=*
boundary=*


Someone got a better solution?

The Validator is marking two ways sharing some nodes as overlapping. While in general this is wanted, I've just encountered a case where it's a false positive: One of the ways is highway=*, the other is natural=*. Personally, I'd rather use some relation for the boundary (containing the street as a member), I don't think it's really wrong. To remove these false positives, we'd probably need to create some "feature groups" where ways of different groups coexist peacefully, but members of the same group conflict.

On second thought, overlapping ways even within a member of this group are often false positives: Unless a relation is used, adjoining areas will usually share nodes. Since the Overlapping check is different from the Crossing check (so intersecting areas are still cought), I'd probably just restrict the former one to the case where ALL nodes of one way are part of the other way.
