That could well be. Many river borders are defined in laws/treaties as the actual river meaning they move when the river changes its course. There are still different variants of definition like center line of the river on either side as well as special contructs like a Condominium for the river itself as in parts of the Luxembourg/Germany border. It is also important to keep in mind that in case of borders authoritively defined through discrete points an officially released data set does not necessarily represent exactly this definition. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
