    摘要: A map information delivery system, including a navigation apparatus, is capable of preferentially receiving map updating information based on a host vehicle's state. The updating information may be preferentially received based on whether a destination has been set, a location of the updating information relative to an updating position or a destination, and/or the size of the updating information.

    摘要: Map information distribution systems and methods store map information and version information for each road category of the map information stored in a navigation device, the version information correlated with identification information identifying the navigation device. The systems and methods receive the identification information from the navigation device and obtain, based on the received identification information, the version information for each road category of the map information stored in the navigation device corresponding to the stored identification information. The systems and methods extract, based on the obtained version information for each road category, differential data for each road category with stored map information of a latest version, and transmit the extracted differential data for each road category to the navigation device corresponding to the received identification information.

    摘要: To provide a data updating system and the like for easily performing updating the difference for the database which contains a large amount of data, each piece of the data being highly correlated, such as a map database that contains road network data.According to the present invention, the data updating system includes a terminal device running according to a predefined operating program, and servers providing the terminal device with a differential data file for updating a database. The terminal includes a local database in an updating data format differing from a reference data format to be referenced to by the operating program and being updated with the differential data file, and a conversion means converting data stored in the local database so as to have the reference data format. The servers include a differential data file output means outputting the differential data file to be provided to the terminal device.
