I'm looking to tag natural features as surveyed on the ground, not political or administrative boundaries. Sure the boundary is fuzzy but we can still get it close.

Agreed. coastline=pelagic, natural=ria all are potential ways to help here. For me Botany Bay (http://www.openstreetmap.org/relation/1214649) isn't part of the open ocean but Bondi Bay (http://www.openstreetmap.org/node/926183187) is, even though both offer shelter.

Exactly. According to https://en.wikipedia.org/wiki/Baseline_(sea), the baseline political, they are like an administrative boundary. That's a separate discussion, I'm only talking about natural features here. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
