I think it's pretty obvious by this stage that OSM is more than just for navigational uses. And I think it's too late to try to restrict it back to just that. So I think the ability to map roads as "directed areas" is worth looking into - this seems to me to be the only problem raised so far about the original poster's question, i.e. "mapping everything as areas" (are there others?). For directed areas, I actually quite like Teemu's idea of using an ordered set of node-pairs. Any issues with that, or alternatives? Re: Morten's suggestion of a "multiplex", is that just for intersections? If not, could you explain how you would use a "multiplex" to map a road or lane as a directed area? _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
