In this case, my recommendation is to tag these features as natural=mesa. You can map this as an area (closed way or multipolygon) that matches the cliffs. I did not try to change the definition of "natural=plateau", because it is already used for many other types of generally flatish highland features, including high plains, high valleys, terraces, and general highland areas. That's why natural=mesa is proposed as a new tag with a more specific definition, which happens to match the geological use of "mesa" as well as being pretty close to the every-day meaning of "mesa" in at least some dialects of English. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
