To provide a position related information presentation system that allows a user
to experience as if the user had actually walked round and collected information
about an area. A 3D map/information superimposed displaying portion reads 3D map
data from a 3D map storing portion and displays area information such as town information
related to the area displayed on the 3D map superimposed on the 3D map to the user.

to a new display position from an area information storing portion. About the display

portion detects superimposing of one object on another such as buildings when viewed
from the current position of the user using the map of the map database. A position
information filtering portion searches for information related to objects visible
to the user from the searched area information.
