Google uses image tiles to show the detail on the map, one set of tiles is created for each zoom level. You can see this by examining the contents of a Google map web page for images, each tile is 256x256 pixels and the mapping system "stitches" them together to form a coherent image.
The data behind the map isn't available directly, however, you can get coordinates of world cities (as points) from Geonames.org among other places. You'll need to construct a database to use the data. -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.
