[talk-ph] Tagging marine features (was: request edit for this month (coastline))

[Mike Collinson]

I've changed the subject to avoid hijacking the original thread.  As Manning suggests, this is something we the Philippines OSM community can take a lead in.

So far, I've not come up with a very large "subsea" list.  Over the weekend I'll try and dig up a list of what GNS uses and how I have mapped some of them to "new" OSM tags.

I have a strong background in marine earth science but zero feeling for what the yachting, boating and shipping community would like to see (sea?!) on maps so any comments on that very welcome.

Another tag I have started using is name=xxx, place=archipelago for a group of islands.  I can then tag islands with an extra is_in:archipelago=xxx tag.  This generally works well except when there is a small group of  islands inside a larger one.  This then needs an island to be tagged with something like is_in:archipelago=Visayas;xxx which is a bit awkward.
