This is for the determination of territorial waters and economic zones; on maps areas between low and high tide are usually not considered land, and as far as I know they are also counted as water area, not land area for determination of the area of countries and other entities. As an example, in the north of the Netherlands and the northeast of Germany there are some outlaying islands (the Wadden Islands), and the area between consists of flats of land falling dry at low tide with deeper 'flow lines' in between. On maps both of these are shown as sea. -- André Engels, andreeng...@gmail.com _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
