    摘要: When an update instruction to update “A” navigation map information and “B” navigation map information is inputted, a CPU initializes the storage area having stored therein no map information currently in use out of the two storage areas. The CPU then reads, from a CD-ROM, the latest version of the “A” navigation map information or the “B” navigation map information that corresponds to the map information currently in use, and stores it in the initialized storage area. The CPU then updates management information, starts use of the newly stored map information, initializes the storage area having stored therein the map information whose use is stopped out of the two storage areas, reads, from the CD-ROM, the latest version of the “A” navigation map information or the “B” navigation map information not currently in use, and stores it in the initialized storage area.

    摘要: In map data having link information, each of the links has reference information regarding a start point node of the link, a next link in a series of links, and an upper link. Further, links are memorized in a form of link list, and the position of the link in the link list is not changed in the course of adding/deleting a link, thereby enabling a direct reference to each of the links in the link list by the position of the link. The link information organized in the above-described manner enables the ease of the update of the map data as well as the speed-up of the calculation of, for example, a navigation route.

    摘要: Vehicular swept path data and electronic map data representing a road map are compared with each other to compute correction information that represents the amount of deviation of the electronic map data from the vehicular swept path data with respect to each predetermined block. The electronic map data is corrected using the computed correction information, and the corrected electronic map data is provided.

    摘要: A navigation device has a regional map data item for each of multiple regions, into which a nation is divided. A connection table is included in a regional map data item for a certain region and associates (i) a certain ID of a connection road in the certain region with a certain connection number. The connection road is connected with a paired connection road in an adjacent region. A connection table of a regional map data item for the adjacent region associates an ID of the paired connection road with the same connection number as the certain connection number. When the certain ID in the certain region is replaced with a different ID because of a road construction or the like, only the certain ID is replaced in the connection table with the certain connection number unchanged. This eliminates need of amending the connection table for the adjacent region.
