Ranges are what 'all the others' use and are familiar territory for all navigation applications. They rarely if ever rely on address points and do interpolation, which works well in urban areas but can be miles off in rural areas. I think that ranges are good for a first iteration because they're less cumbersome to collect and map. They do require cutting up the ways at junctions like Richard mentions. Where there's no data available to import and / or not a lot of local mappers, ranges may be as good as it gets for OSM. Where there is good quality data to import and/or enough dedicated mappers, they should be replaced by address points, I think. Another thought: the ranges could be derived from the cross streets, couldn't they? At least here in Salt Lake the addresses on 900W between 100S and 200S are all in the 100-200 range. And if they can be derived, what use is it to duplicate the information? -- martijn van exel geospatial omnivore 1109 1st ave #2 salt lake city, ut 84103 801-550-5815 http://oegeo.wordpress.com _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
