For much the same as the reasons given here: http://www.census.gov/geo/www/tiger/tigermap.html#ZIP "The fact that ZIP Codes aren't required to be polygons makes them difficult to map. They are networks of streets served by mail carriers or just individual post offices and are a tool for mail delivery. They also change periodically as required to meet Post Office operational needs. Various companies have created maps by interpolating boundaries between occurrences of ZIP Codes on the ground. However, this does not guarantee that the U.S. Postal Service delivery routes will follow this interpretation." _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
