| 20110170536 | Network path finding apparatus, method, and program - To perform a path finding for a network by traversing mutually connected links by means of a link destination table that is a data configuration for representing the network. The link destination table contains, for link IDs of each of the links in the network, a node ID of a node on one side of the link, destination link IDs for the node on one side which are link IDs of other links to that node, a node ID of the node on the other side of the link, destination link IDs of the node on the other side which are link IDs of other links to that node, and interval costs. | 07-14-2011 |
| 20100023554 | Apparatus, program, and method for map data update - 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. | 01-28-2010 |
