Abstract
The present landmark update system enables route guidance through the use of landmark information which remains always the latest for route guidance, and operates as follows: a navigation device 1 communicates with a landmark server 30 so as to receive to-be-updated landmark information 1001 for guiding the user by utilizing landmarks. Information about any landmark displayed is transferred to the landmark server 30 as cumulative information 1002. The landmark server 30 manages the cumulative information 1002 so that compilation data 1003 is generated for transfer to a retailer terminal 40 corresponding to the displayed landmark(s). The retailer terminal 40 refers to the compilation data 1003 so as to generate landmark information which is considered optimum, and transfers it to the landmark server 30 as registering landmark information 1004.
