I like mine better... http://maps.huge.info/zipcolors.htm
This is actually quite simple to accomplish. You'll need a database of geocoded Zip Codes, not the polygons (except if you want to paint them on a map), just the centroids. A reasonable database will cost about $200. Be wary of free ones. Once you have the database, it's a simple matter of running through the table, compute distance from the target Zip Code centroid to the centroids of other ZIp Codes and pick out the ones that fall within the distance criteria. The Haversine formula will give you that distance. It's pretty easy to code in virtually any language. If you have Postgresql, it's really, really easy. That's all there is to it. -John Coryat -- You received this message because you are subscribed to the Google Groups "Google Maps API V2" group.
