Hi Christian, Thanks for your answer. Unfortunately, it is not what I want, not at all. For example, if the base map is composed of these four tiles : http://c.tile.openstreetmap.org/17/68090/47886.png http://c.tile.openstreetmap.org/17/68091/47886.png http://c.tile.openstreetmap.org/17/68090/47887.png http://c.tile.openstreetmap.org/17/68091/47887.png I want that the overview looks like : http://a.tile.openstreetmap.org/16/34045/23943.png It is completely different from an average of the four tiles.
