    摘要: A data updating system includes a navigation device running according to a predefined application program; and a server providing the navigation device with a differential data file for updating a database containing road network data. The navigation device includes a navigation memory storing a local database in an updating data format in which the road network data is arranged in the order of data types and to be updated with the differential data file; and a navigation controller that converts data stored in the local database so as to have the reference data format in which the road network data is arranged in the order of connection of the road network to be referenced to by the application program. The server includes a server controller that outputs the differential data file to be provided to the navigation device.

    摘要: A map update data supply apparatus includes: isolation detection means for detecting the presence and the absence of an isolated state in which some of the roads are isolated from other roads in a road network of target map data due to updating of one or more update target segments of the target map data based on update map data; extraction means for extracting, as update required segments, segments of the update map data, other than the update target segments, that have a road that connects to the isolated some of the roads when it is detected that there is the isolated state; and update data file generating means for generating update data files for the update target segments and the update required segments based on the update map data.
