One easy way to create areas is to use "My Maps" at maps.google.com with the "Draw a Shape" function. These areas are stored in googles databases. To get a reference to an area, you can right click on the "View in Google Earth" link and copy the URL. These links can be included in a javascript API map using GGeoXml, for example the following map of 4 Census Collection Districts in Sydney (which are approximately 200 houses per district) http://www.william-map.com/20100505/1/map.htm ... -- You received this message because you are subscribed to the Google Groups "Google Maps API" group.
