For example, when the moving speed of the user is high, the layer data indicating the attribute close to the user's position is preferentially requested, or when the user searches for a specific place and is moving, It is possible to preferentially request the layer data to be represented.

As described above, the terminal control unit 260 confirms the main line of the user of the terminal device 200. By tracking the position of the user calculated by the GPS unit 250 for a predetermined period, the user can extract the main line of the user. Also, the user's schedule information can be input and the user's main movement line can be extracted from the schedule of the user, and the schedule of the user includes the user's movement route for a certain period of time in the future.

The terminal control unit 260 checks the main circulation line of the user of the terminal apparatus 200 and transmits the main circulation information of the user of the terminal apparatus 200 to the service apparatus 100 and the main circulation information of the terminal apparatus 200 stored in the terminal apparatus 200 The version information of the stored data can be transmitted. In this case, as described above, the service device 100 checks the main copper information of the user of the terminal device 200 and receives only the map data update information matched thereto. When receiving the partial map data update information, the terminal control unit 260 transmits at least one of the required partial map update information using at least one of the setting information of the terminal apparatus 200 or the moving state of the terminal apparatus 200, Data can be extracted.
