Coastlines in 3D landscapes

  1. What would you have the arch area cover? Just the span of the arch, or also a wider area including the supports on either side? The latter seems tempting when the arch columns are well delimited, like in this case: Es Pontàs - Wikipedia. But in the case I mentioned earlier the “support” of the arch isn’t clearly outlined, so I guess it makes more sense to cover just the span.

  2. One of the things I want to respect is the fact that the coastline actually goes though the culvert, which is the reality on the ground. Tagging as natural=water without coastlines kind of disguises this fact. I guess I could tag as both though. An alternative, following the pattern of natural=arch could be to revive natural=land with layer=1 for the land area above the culvert.
