A detailed map is displayed on a display screen by using detailed map information. When a building BL on the detailed map is indicated, a user name list of the building is calculated from building information to display the user name list on a part of the display screen, and a detailed map MP displayed on another part of the display screen is inclined by a birds-eye process to be displayed. The indicated building BL is displayed three-dimensionally with a height corresponding to the number of its floors. When a user is specified from the user name list, the floor number of a floor on which the user is located is calculated from the building information. The floor is displayed by an L-shaped mark FL in the three-dimensionally displayed building such that the number of floors can be identified, and/or the floor number is displayed by the characters FLC.
