  • Patent number: 9697426
    Abstract: A method of encoding a continuous path within a road network is described, the path being completely represented within a digital map and expressible as a path list of lines and/or segments existing in said digital map and consecutively ordered, wherein said lines and/or segments have one or more attributes associated therewith. The method involves storing a start position in a route search list, and determining a path from the start node of the start position and including said start position to an end node of the last line or segment in the path list within said digital map. The path is determined according to an algorithm utilizing an attribute of said lines or segments. The attribute may be a lowest functional road class (LFRC) of the path to be encoded or a part thereof.

  • Patent number: 8818707
    Abstract: A method, of resolving a location from an ordered list of location reference points being representative of nodes in an encoder digital map and each having attributes representative of a specific line or segment in the encoder digital map emanating from or incident at those nodes, is disclosed.

  • Publication number: 20110118971
    Abstract: An efficient method of encoding a continuous path within a road network is described. Ideally the path to be encoded is capable of being completely represented within a digital map and expressible as a path list of lines and/or segments existing in the digital map and consecutively ordered.
