One interesting method of polygon display is the whole image overlay method. I use this in the following demo:
http://maps.huge.info/zipcolors.htm This demo uses a total of around 31,000 polygons, so is comparable to what you've got. The idea here is to pre-render all polygons into images, one image per polygon and render the images in several colors and zoom levels (three colors, three zoom levels). The end result is very good performance, ability to change the colors of the polygons dynamically and also select the size of the image to use based on the bounds of the display. The downside is it's fairly complex to setup, both more complex and yet simpler than tiles, depending on how you look at it. Skill level wise, I rate this a 7 on a 1 to 10 scale. -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.
