There are large parts of tropical coastlines where the coast is marked as the outside edge of mangrove swamps. These are covered with water most of the time, and adjacent to the sea, so are below the "high tide" line, but are considered to be part of the land. You can't take a boat through them, and they're covered with trees. These have been discussed on the mailing lists several times. The general consensus seems to be that if it's covered in plants, it's inside the coastline, even if there happens to be water cover as well.
In some places, we're talking about differences of 15-20km or so in where the coastline goes, so it's easy to see what paper maps have done, and every one I've checked includes coastal swamps (fens?) and mangrove flats on the land side of the coast. 2009/4/30 Cartinus <carti...@xs4all.nl>: > I can't find anything about moving the coastline away from the high-tide line > in either: > <http://wiki.openstreetmap.org/wiki/Talk:Tag:natural=wetland> > or > <http://wiki.openstreetmap.org/wiki/Talk:Tag:natural=coastline> > > The second page e.g. talks about a sandbank at the coast of the isle of Wight. > Which, according to that discussion, should be on the sea-side of the > coastline. > _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
