Abstract
Systems and methods of route guidance on a user device are provided. In one aspect, a system and method transmit partitions of map data to a client device. Each map partition may contain road geometries, road names, road network topology, or any other information needed to provide turn-by-turn navigation or driving directions within the partition. Each map partition may be encoded with enough data to allow them to be stitched together to form a larger map. Map partitions may be fetched along each route to be used in the event of a network outage or other loss of network connectivity. For example, if a user deviates from the original route and a network outage occurs, the map data may be assembled and a routing algorithm may be applied to the map data in order to direct the user back to the original route.
