You'll first have to decide on what you mean by that, three possibilities come to mind:
1. That "touch" the radius. 2. That are "contained within" the radius. 3. Where the centroid point is contained within the radius. All three of these methods require a geocoded database of zip codes. The first two require polygon coordinates the third only requires the centroid point. To actually do the search, you'll need to have a spatially aware database and run an SQL query. Technically, it's not challenging but can be daunting if you haven't done this type of thing before. -John Coryat http://maps.huge.info http://www.usnaviguide.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
