ABSTRACT:
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. When the user changes a display of the 3D map by using a display change inputting portion, a position information searching portion searches for information related to a new display position from an area information storing portion. About the display of the area information superimposed on the 3D map, the field of view determining 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.
