A waterbody where plant and animal life matches or is close to that of the sea rather to that of a river or lake. > Botany Bay is unlike many conventional bays which are on the > coastline and part of the sea.

An esturary is the transit of a river into the ocean. If you consider the Botany Bay to be part of the esturary of Georges River you still have to decide where you place the coastline and if you place it below the bay you have to tag the bay waterway=riverbank or natural=water + water=river. Creating a separate waterbody that is not part of the river but within the coastline is wrong in our current tagging scheme. Note in general the esturary of Georges River would be considered to start much further upstream, likely somewhere around here: https://www.openstreetmap.org/#map=15/-33.9765/151.0237 at the transit from a meandering river to a ria (https://en.wikipedia.org/wiki/Ria). -- Christoph Hormann http://www.imagico.de/ _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
