I'd like to put an overlay over de borders of a Dutch postal code. Google Maps does this like a charm in their normal interface. It puts a dashed border around the bounds of the postal code.
But the Google Maps Geocoding API only returns a right-upper and lef-under limit:
http://maps.googleapis.com/maps/api/geocode/json?address=3335,+NL&sensor=true
Has anybody got any clue on how to tackle this, so that we can put a polygon overlay over the exact borders of the Dutch postal code? Any other services besides Google Maps are okay for us too, we've looked at others yet.
Kind regards, Gerard Nijboer
