A Zip Code is a routing code. It doesn't represent geography any more than you can do a 1:1 mapping of iP address to physical location. You can do a "Pretty good" job by simplifying the data, but zip codes are attributes of addresses, not regions. If you want to add these zip codes to objects with addr fields, that would be accurate, but you can't accurately represent a zip code as a region. - Serge _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
