Abstract
Abstract An object is to realize a server/client-type map information providing system capable of providing detailed, wide-ranging map related information through telecommunications at low costs, and a server side is provided with databases (9 to 12) storing the map related information. When notified of position information from a mobile terminal side, a processing portion 15 performs route search referring to map data in the map database 9 based on the position information. The processing portion 15 then extracts information related to the obtained route (route related information) from the databases (9 to 12) to transmit the information with the route to the mobile terminal side. In this way, since the mobile terminal side needs only the information that is closely related to the route in the map related information, only the route related information is transmitted, thereby reducing the amount of information to be transmitted compared to that when the map related information is downloaded as it is, and as a result it is possible to provide detailed, wide-ranging map related information through telecommunications at low costs.
