A mesa can be large. The defining characteristic is that the top is flat, but it is surrounded by cliffs: it looks like a table-top. I've tried to make it clear how butte and mesa differ: A butte is a hill where the peak is surrounded by cliffs, but the diameter of the circle of cliffs is less than the height of hill. The top is flatter than the cliffs around it, but not necessarily table-flat. In contrast, a mesa is wider or longer than it is high, and the top must be flat, and surrounded by cliffs. Perhaps I need to add an image showing a comparison. >> https://wiki.openstreetmap.org/wiki/Proposed_features/Tag:natural%3Dplateau > > The smallest horizontal dimension of a plateau could be 1.6 km ( 1 mile). > This would distinguish it from mesa/butte. I don't think there is a clear definition for plateau. That's why I created the proposal for natural=mesa and natural=butte, which have clear definitions and can be mapped as an area in some cases. While some dictionaries claim that a plateau should be mostly or partially surrounded by an escarpment, some features that are named plateaus do not have this characteristic, and are more like high plains or valleys. I don't actually intend to vote on natural=plateau - the only reason I made a proposal is that this tag is already in use, and I think it is useful to document how it is used. Also it is a good idea to clarify that vague features like plateaus should only be mapped as nodes, rather than as areas. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
