What the level does is to provide information about whether a particular point is "necessary" at a particular zoom. Points are only missed out if they will make no material difference to the shape of the polyline. The relationship between letters and zoom levels is explained by Professor McClure at http://facstaff.unca.edu/mcmcclur/GoogleMaps/EncodePolyline/description.html Andrew --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
