Indeed - not separating actual water mapping from mapping geomorphology is one of the primary disadvantages of the waterway=riverbank tag (for which as said there are advantages too) - and is partly responsible for quite a few cases where water mapping covers the whole floodplain of a braided river like here: http://www.openstreetmap.org/#map=12/46.0764/12.8456 Similar situation by the way with landuse=reservoir/landuse=basin - acutal presence of water vs. dedication of an area for certain use. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
