Abstract
When a map acquisition judgment means judges that the acquisition of map information is required, a terminal device transmits spot position information calculated by a spot information calculation means to a server which mediates providing of the map information, via a first map information providing server where the terminal device is positioned. The server causes an area judgment means to judge according to the spot information an area of providing map information including the spot, identifies a map information providing system on the basis of the judgment, and requests providing of the map information including the spot to a second map information providing server in the area according to the spot position information. The terminal device synthesizes map information held by the terminal and map information provided by the second map information providing server by a map synthesis means and displays the synthesized map information on a display means.
