  • Patent number: 7610147
    Abstract: A map data processing unit includes a batch update section and dynamic update section. A type of update data fed from an update data input section is decided using header information. If the update data is route search data, the batch update section collectively updates all the map data to latest version map data according to the update data from the update data input section. If the update data is not the route search data, the dynamic update section updates the map data to the latest version map data according to the update data every time the map data becomes necessary. Thus performing the collective or dynamic update according to the type of the update data enables the update to the latest map data without affecting the operation speed of a navigation function, with minimizing the time precluding the use of the navigation function.

  • Patent number: 7526492
    Abstract: For map data, a road system is represented by using node data, which is information concerning nodes representing points along a road, and link data, which is information concerning a link representing a road between the points. A link row is a series of links representing a series of roads in a road system, and as link row data, link data for the links that constitute the link row are arranged in the order in which the links are connected. The node data for the individual nodes of the road system are provided separately from the link row data, and to identify nodes, node identifiers are provided for the nodes of the road system. The link data includes information indicating a node identifier for a node that is located at one link end defined in the direction of the link row.

  • Patent number: 7403852
    Abstract: In a road data frame for displaying road maps, each node/link data record describing a link corresponding to a road part includes link identification information identifying an original link, and auxiliary link identification information used for identifying a plurality of alternative links which substitute for any of the original links in the map data. In a route planning data frame for route planning, each connection record describing the interconnection of nodes also includes corresponding link identification information identifying an original link, and corresponding auxiliary link identification information used for identifying a plurality of alternative links which substitute for any of the original links in the map data. By means of identification information of the original link and auxiliary links, it is facilitated to identify the correlation among links in the road data frame and the route planning data frame having different versions.
