1. A computer-implemented method for accessing map tiles, the method comprising:

  • receiving a first request from a computing device for a portion of a map, wherein 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, and wherein the first map tiles from the first type of map include bulk rendered map tiles and one or more individual rerendered map tiles, the one or more individual rerendered map tiles comprising one or more corresponding bulk rendered map tiles modified based on map feature updates;

    providing first tile version identifiers and second tile version identifiers to the computing device in response to receiving the first request, wherein each of the first tile version identifiers uniquely identifies an instance of one of the first map tiles and each of the second tile version identifiers uniquely identifies an instance of one of the second map tiles; and

    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.
