Abstract
There is provided a navigation apparatus which displays information concerning facilities or the like which are present in a broad range ahead of a user. An information processing section 4 of a navigation apparatus identifies a facility type to be displayed. Next, a predicted road along which a user is expected to travel is determined, and a reference intersection is selected from among the intersections on the predicted road. The information processing section 4 computes a network of roads beginning from the selected reference intersection, and acquires facility information in the neighborhood thereof. Furthermore, the information processing section 4 generates facility information image data for displaying the acquired facility information on a map.
