To the best of my knowledge (and experiments I made) this gives me the corners of the rectange currently shown. Critical are only longitudes, since the duplication of map elements happens only in longitude direction. For example I should get -74.0 from the SW corner if the west border of the map intersects New York City and 2.21 from the NE corner if the east border intersects Paris. But cases I intend to detect are more like zoom situations in which, for example, the whole american continent is visible in the west, then going east the whole of Africa, Europa, Asia and Australia is visible and then in the rightmost area of the visible map America appears again. If I enlarge a map by enlarging the browser window I noticed that at some point the west and the east coordinate returned by getBounds() swap, while in fact the west corner of the visible map did not change at all but its east border has been expanded to reach a point shown in the west again. > Bear in mind that standard Google tiles do not cover the whole earth > (polar areas missing) Ok, I see. But that is not relevant in the context I intend to use it. Florian -- You received this message because you are subscribed to the Google Groups "Google Maps API" group.
