US Patent 10002156 Version management for incrementally compiled map data

A map developer may maintain multiple versions of a geographic database including map tile data. Map tile data may be organized according to a versioning schema. A server, or an endpoint device in communication with the server, may receive a request for map data for a tile associated with a tile identifier and access a tile compatibility table with the tile identifier. The tile compatible table includes multiple tile version identifiers for the tile indexed by global map version identifiers and returns a compatible tile identifier and a compatible map version in response to the request for map data.
