Without layer information you'd be guessing if the road goes over the water or the water goes over the road, or the water and road are at the same level. You could come up with sane defaults, but that's making assumptions rather than tagging explicitly so you know beyond a reasonable doubt. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
