There's no guaranteed way to determine what cities are being displayed at any particular zoom level. You could generalize that cities of certain population are being displayed at each zoom, but that would not work for sparsely or heavily populated areas equally. Essentially, you're stuck with either an imperfect solution or a manually derived one.
Geonames.org does have population figures for world cities, so that should help somewhat. The data on their site is available as a download, so you can build your own database and process it as you like. -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.
