FIG. 4 is a flowchart for explaining processing from acquiring map data and feature data from the internal DB 7 in which the terminal position information is written and outputting the map data and the feature data to the screen.

In the mobile terminal device 3, first, GPS information is acquired by the GPS information acquisition unit 10 (step ST1).
The position information processing unit 11 acquires GPS information from the GPS information acquisition unit 10 and generates current position information of the mobile terminal device. The position information processing unit 11 generates terminal position information based on the current position information received from the GPS acquisition unit 10 (step ST2).
The terminal position information is information including terminal position information in a format such as latitude and longitude, current time information, a user name of the terminal, and a terminal number.
The location information processing unit 11 sends the generated terminal location information to the location information transmission unit 12.

The location information transmission unit 12 confirms whether the internal DB 7 is accessible via the network 100 (step ST3), and if accessible, transmits the terminal location information to the internal DB 7.
If it is determined in step ST3 that the internal DB 7 is inaccessible, the accessible external DB 200 is searched (step ST4). If there is no accessible external DB 200, the terminal location information is stored in time sequence in the location information storage unit 13 inside the terminal (step ST5). Thereafter, the process returns to the process of confirming the access state of the internal DB at regular or arbitrary times (step ST3), and the stored terminal location information is written.

If there is an accessible external DB 200 as a result of the search in step ST4, terminal location information is transmitted to the external DB 200 and data is written (step ST5).
The external DB processing unit 9 accesses the external DB 200 periodically or in response to a request from the map information processing unit 5, refers to the data, and acquires terminal location information stored in the external DB 200 (step ST6).
The external DB processing unit 9 passes the terminal location information acquired from the external DB 200 in step ST6 to the DB processing unit 8, and the DB processing unit 8 writes the terminal location information acquired from the external DB 200 in the internal DB 7 as feature data ( Step ST7).

The map information processing unit 11 requests map information from the DB processing unit 8 periodically or at any time.
The DB processing unit 8 acquires map data and feature data from the internal DB 7 (step ST11), and passes them to the map information processing unit 11.
The map information processing unit 11 determines whether data has been updated (step ST12), and if not updated, ends the processing. If the data has been updated, the map information processing unit 11 generates map information from the map data and the feature data (step ST13) and passes it to the display unit 6.
The display unit 6 converts the received map information into a display format according to the user's request, generates display information (step ST14), and passes it to the display device 4. The display device 4 outputs the acquired display information to the screen (step ST15).
