While neither a Google Maps API question, nor a Boolean operation, what you want is the difference between two polygons.
There may be someone who has written a Javascript version of this, but I don't think so, which means you'll have to do it on the server side. I recommend using a PostGIS enabled PostgreSQL database and the ST_Difference function. It works quite well, is a no cost system and is very powerful with lots of very cool functions. -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.
