Are you suggesting that there are no relevant differences between a man-made tunnel and a cave? I can think of a lot – naturally formed, uneven walls and floors, varying height and so on. In general, it's also a lot easier for applications to treat two tags the same than to treat the same tag differently. So I think you really should distinguish between caves and tunnels. If you don't want a new key, then use tunnel=cave or something. But in my opinion, cave=yes would also work fine. _______________________________________________ Tagging mailing list [email protected] https://lists.openstreetmap.org/listinfo/tagging
