Abstract: The subject matter of this specification can be implemented in, among other things, a computer-implemented method for updating map tiles. The method includes receiving updates to features in geospatial information that describes a map. The map is represented by multiple tiles. The method further includes rerendering at least one tile from the tiles based on the update to generate an individual rerendered instance of the tile. The method further includes storing a tile version identifier and an association between the tile version identifier and the individual rerendered instance of the tile. The method further includes providing the tile version identifier, instructions for using the tile version identifier to send a request for the individual rerendered instance of the tile, instructions for replacing an existing instance of the tile with the individual rerendered instance of the tile, and instructions for ceasing overlaying of a temporary display object on the map.

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.
