this depends on the level of detail the map has. In the early days I also found this quite often, while now with the mapping advancing this gets less. I suggest to split the way at the situation where you apply a layer tag to avoid these problems with long ways carrying a layer tag. > whether the river is at or below ground level is another opinion which > varies in different environments Yes, but I'd call subterranean rivers an exception. Usually rivers are at ground level. Cheers, Martin _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
