Abstract:
Systems, methods, and apparatuses are described for updating navigational map data. A routing request is received from a user or device. From the routing request, a first map tile and a second map tile are identified. A new version of the first map tile is identified, and a compatibility matrix for at least the first map tile is accessed. An analysis of the compatibility matrix is performed to determine whether objects of the new version of the first map tile are compatible with the second map tile.
