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 road map data structure includes road network data Rn, representing roads by a connection relation of a plurality of links L, in a hierarchical structure of a plurality of levels, in which, as a link ID for each link L at a lowest level, consecutive serial IDs, according to a connection order of the links within a link line ML formed of a plurality of the consecutive links having a common attribute, are assigned to first links L1 which have a corresponding link existing at a higher level, and a permanent ID, irrelevant with the connection order of the links, is assigned to a second link L2 which does not have a corresponding link existing at a higher level.

摘要： Systems, methods, and programs create a road map data structure, the data structure including road network data in which a road is represented by a plurality of links connected in a link string. The systems, methods, and programs assign a link ID to each of the links of the road network data. For each link, the link ID has a numerical range set in accordance with both a length of the link and a road attribute, and the link ID is set sequentially in a connection order within the link string.

摘要： Systems, methods, and programs for updating map data create differential data in a server by comparing an old version of map data stored in the server with a new version of map data and transmit the differential data from the server to a relay device. The systems, methods and programs create updated map data by combining the differential data received from the server with map data previously stored in the relay device. The relay device may then be connected to an updated data storing device that disconnectably connects to both the relay device and the navigation system. The systems, methods, and programs, may then transfer the updated map data from the relay device to the updated data storing device and from the updated data storing device to the navigation system.
