+1, this is really odd as well. I think for "forward clarity" it would be better to render these inner holes as forests as well, so the mappers will probably remove this tag if it isn't a forest. It just gets too complicated and weird otherwise. E.g. how would you treat a multipolygon tagged as landuse=forest with an inner hole tagged itself as natural=wood? You can't asume in OSM that the same feature will always have the same tags to describe it. There could also be reasons (e.g. boundaries, names) why someone cuts a hole into a forest where also the hole is a forest (with different properties). cheers, Martin _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
