English term or phrase: an updating spot | According to a seventh aspect, there is provided the map information distribution system according to the sixth aspect, wherein the navigation device further comprises: a vehicle status detector detecting a vehicle status; a destination setting section for setting a destination; an updating spot storage storing a pre-registered updating spot; and a flag setting section for setting ON/OFF of a coordinate flag; the request data transmitting section transmits a coordinate flag set to ON and a coordinate position of the updating spot as the updating request data as the vehicle status detected by the vehicle status detector is at engine start, and transmits a coordinate flag set to OFF and a coordinate position of the destination as the updating request data as the vehicle status detected by the vehicle status detector is at destination setting, and the map information distribution center comprises: an area selection section selecting, as the request data receiving section receives the coordinate flag set to ON and the coordinate position, a first area centered by the coordinate position as the predefined area, and selecting, as the request data receiving section receives the coordinate flag set to OFF and the coordinate position, a second area centered by the coordinate position as the predefined area. In a map information distribution system according to a seventh aspect, a navigation device transmits a coordinate flag which is set to ON and a coordinate position of a pre-registered updating spot as updating request data to a map information distribution center at engine start. Upon receiving the coordinate flag which is set to ON as the updating request data and the coordinate position, the map information distribution center sets a first area centered by the coordinate position as a predefined area for updating map information. The navigation device, when setting a destination, transmits the coordinate flag which is set to OFF and a coordinate position of the destination as the updating request data to the map information distribution center. Upon receiving the coordinate flag which is set to OFF as the updating request data and the coordinate position, the map information distribution center sets a second area centered by the coordinate position as a predefined area for updating map information. The updating map information 17 stored in the center map information database 14 stores various types of information required for route guidance and map display of the navigation device 2 including, for example, map display data to display maps, intersection data relating to intersections, node data relating, to node points, link data relating to roads (links) as one of facilities, search data to search routes, shop data relating to point of interest (POI) such as a shop as one of facilities, and spot search data to search spots. The navigation map information database 37 stores navigation map information 38 which is used for route guidance and route searching of the navigation device 2 and is the subject to update by the map information distribution center 3 as well. The navigation map information 38 includes, similar to the updating map information 17, various types of information required for route guidance and map display, for example, new road data to identify newly constructed roads, map display data to display maps, intersection data relating to intersections, node data relating to node points, link data relating to roads (links) as one of facilities, search data to search routes, shop data relating to POI such as a shop as one of facilities, and spot search data to search spots. As the details of various types of data have been described already, their details are omitted here. |
