I don't see what information is missing and cannot be easily determined automatically with a properly placed node that is contained in an area - except for the outer edge of course, which is usually ill-defined though as you said yourself. If you think about it a bit and do not try to place the node where you would place the label (which depends on the map projection anyway) properly placing a node for a bay is usually quite simple. The most difficult are long, fjord-like bays where a way along them would be more appropriate. Specific arguments aside - i am not sure if you realize the consequences it would have if subareas of oceans would generally be mapped as polygons - large bays usually contain smaller bays and are parts of a sea and there might be a strait between an island and the coast within that bay. If you want to edit the coastline in such situation you would end up having to deal with a handful of convoluted multipolygon relations, some of them of colossal size. Properly editing coastlines is difficult for beginners in the first place. This would make it borderline impossible. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
