Abstract: The subject matter of this specification can be implemented in, among other things, a computer-implemented method for accessing map tiles. The method includes receiving a first request from a computing device for a portion of a map. The portion of the map includes combined map tiles that are a combination of corresponding ones of first map tiles from a first type of map and second map tiles from a second type of map. The method further includes providing first tile version identifiers and second tile version identifiers to the computing device in response to receiving the first request. The method further includes providing instructions to the computing device for using the first tile version identifiers and the second tile version identifiers to request the combined map tiles.
