A few years ago, you could pretty much assume that any untagged segment in the OSM database was a road. Renderers would display them as such, and any routing programs of that era would have followed them. Since the tagging evolved beyond just "types of road", most software has stopped rendering unknown objects as unclassified roads. So this kind of change (where all software has to gradually abandon assumptions about the data) has been done before? _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
