When information regarding position of a facility, such as a parking lot, is requested from a terminal (22), an information center (10) supplies position information to the terminal (22) as a relative position using a landmark, such as a neighboring road. The terminal (22) computes a shift from a position of a landmark in a local map database (24) and a position of a received landmark in a map matching processor (34), and corrects the facility position. If the landmark has not been stored in the map database (24) at the terminal (22), relative data based on another road is resent.
