I have no idea since I can't even convert it to OSM format quite yet. I'm in the process of converting the old ruby code over to perl. I hate ruby with a passion, and I think it slowed me down horribly last time. In the newer code, I will make a substantial effort to fix up some of the things that were wrong with the old code: 1. No "braided streets". My old code just tried to make individual ways with the same name as long as possible. I need to be more careful at 3/4-way *intersections* when the ways have the same name. 2. Follow motorway_links and ensure they hit motorways. TIGER only has one 'onramp' tag, and it got converted wholesale to highway=motorway_link, even when it is nowhere near a motorway 3. Pay more attention to connections. Don't let motorways and highway=residential share nodes as easily. Anyone want to add to my list? How about put it on the wiki for me? ;) -- Dave _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
