Abstract
Obtaining a map update information related to a change caused by a new establishment or razing of a road or facility or the like, only in a case that a re-confirm is possible from a different information source, update a map information. Each of terminal apparatuses obtains a position information, transmits the obtained position information to the central apparatus, and obtains the map update information related to the change in the facility or road, and then transmits the obtained map update information to the central apparatus. The central apparatus receives the position information and the map update information, and compares with a map update information, and consequently judges whether or not there is any difference from the map information. If there is the difference, this transmits a confirm request to a different terminal apparatus, and when receiving a confirm report indicative of the normality, updates the stored map information.
