The best way to handle too many markers on a map is to skip markers altogether and use a tile overlay.
Here's one I did recently: http://www.usnaviguide.com/volcano.htm This one uses a combination of a tile layer to show all the volcanoes in the world and a KMZ from the Smithsonian to show ones that are currently "interesting." There are about 1500 volcanoes showing on this map and currently 14 interesting ones. The zoom levels are from 4 to 9. -John Coryat http://maps.huge.info http://www.usnaviguide.com http://www.zipmaps.net -- You received this message because you are subscribed to the Google Groups "Google Maps API" group.
