Adding a oneway tag explicitly says that it flows that way. If there's no oneway tag it may have been mapped without regard for or knowledge of the direction. It also makes it possible to see errors - how are you going to get enough eyeballs if none of those eyeballs can see which way the waterways are tagged? _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
