The size should double for each zoom level. However, if you're going to be dealing with large areas, you may also need to vary the size depending on latitude. In the Mercator projection, the amount of ground covered by 25 pixels increases as you move away from the equator. -- http://econym.org.uk/gmap The Blackpool Community Church Javascript Team --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
