Abstract: An approach is provided for vehicle map data update. The approach involves, for example, processing sensor data captured by a sensor of a vehicle to detect a machine-readable visual representation. The machine-readable visual representation encodes map data corresponding to a map tile of a geographic database. The approach also involves decoding the map data from the machine-readable visual representation. The approach further involves updating a local copy of the map tile stored in the vehicle based on the map data.

Abstract: Aspects described herein provide a computer-implemented method and system for generating topographic map data at different scales. More specifically, the topographic map data is reduced from large scale to small scale, wherein the scale of the vector features is reduced according to their geometry, feature type and attributes. In order to quickly and easily output digital maps at different scales so that a user may quickly zoom in and out of a map, different zoom levels are produced for different scales, each zoom level containing a variable amount of detail according to its scale, with larger scale zoom levels generally containing more detail than small scale zoom levels. Each zoom level is made up of one or more vector tiles representative of a geographic area, wherein the vector tiles may contain one or more vector features that are representative of objects within that geographic area, and other information related to that geographical area.

Abstract: To update a database of a navigation device which stores at least a base version of a digital map, versions of the digital map which are available locally in the database or remotely from the navigation device are identified. To execute the navigation task, a version of the digital map is selected for execution of the navigation task. Data from a sub-set of storage blocks in which the selected version is stored is required to execute the navigation task. Depending on whether all storage blocks of the sub-set are already stored locally in the database, data stored in storage blocks of the sub-set which are not yet stored locally in the database are downloaded via a wireless interface. The downloaded data are stored in the database without modifying the base version of the digital map.

Abstract: Systems, methods, and devices are described for implementing map matching techniques relating to measured location data. Probabilistic models, including temporal Bayesian network models and Hidden Markov Models, may be used for combining multiple classes of evidence relating to potential locations of points traversed on routes over time. Multiple route segments and overall routes may be maintained under relative uncertainty as candidates. The candidate route segments and overall routes may then be reduced into a smaller number of candidates or a single most likely route as a trip progresses. As the trip progresses, route segments in proximity to each location point are identified and candidate matches are determined. A probability of an entity traversing a candidate match at a given time and a probability of an entity traversing between a first candidate match at a first time and a second candidate match at a second time are determined based on a plurality of factors.
