Abstract: A system and method determines a path in an open space that does not have a well-structured routing infrastructure. In some embodiments, the system and method may model the open space with one-dimensional segments. The system and method may determine a path between two points along the one-dimensional segments. In some embodiment, the system and method may smooth the path based on geometry of objects in the open space.

Abstract: A path made up of several points including an origin, a destination, and intermediate points, is determined. Map data is fetched from an external map database to a local memory of a client device prior to detecting a need to use the map data for rendering maps at the client device. To this end, respective priorities of the points are determined, amounts of map data to be fetched are determined based on the determined priorities, and map data is fetched in accordance with the determined priorities, so that a first amount of map data is fetched for a point with a first priority and a second amount of map data for a point with a second priority, where the first amount is greater from the second amount. Respective digital maps of the one the geographic areas are generated using the pre-fetched map data stored in the local memory.

Abstract: The present application describes techniques for fetching map data as a selected subset of entire map data available by selecting map data tiles corresponding to an area that encompasses a route. An amount of map data accessed may be adjusted based on a priority assigned to areas or points along the route. A sequence of map data may be accessed based on a priority assigned to sets of map data.

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.
