The API can help, up to a point. See http://econym.org.uk/gmap/epoly.htm for an extension which can test whether a polygon contains a point. Note that if you have a large number of polygons this will not be the most efficient method, even with the bounds checking. It would be more efficient to use server-side checking, either using point-in-polygon analysis or a spatially-enabled database. -- You received this message because you are subscribed to the Google Groups "Google Maps API" group.
