what about natural=boulder for a remarkable rock? There are only a disappointing 18 occurrences, but maybe with some promotion...
I would also be fine with natural=rock like it is suggested by you. Completely agree that natural=rock for rock covered areas doesn't fit well in the tagging scheme (it is not a topographical feature o type/class of terrain but a physical description), better use landcover or surface instead of the natural key for these. cheers, Martin _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
