A map information providing system for providing map data to a terminal device via a data transmission path, includes: a first server, the first server including a first storage unit for storing map data; and a second server connected with the first server and the terminal device via a network, the second server including a second storage unit for storing the map data. The first server includes: a unit for producing map search table which designates at least one of the first storage unit, the second storage unit and a third storage unit in the terminal device, from which certain map data is to be obtained; and a unit for transmitting the produced map searching table to the terminal device to be stored in the terminal device.

Map information providing system and map information searching method

The route calculation server receives starting point data and destination data corresponding to a starting point and a destination which a user designates by the user terminal, and calculates a route from the starting point to the destination. The map server includes a map database, and communicates with the user terminal via the network. The route calculation server stores calculated route data together with route identification information associated with the route data, and transmits the route identification information to the user terminal via the network. The map server receives the route identification information from the user terminal via the network, obtains the route data associated with the route identification information from the route calculation server, produces route display picture data including map picture on which the calculated route is represented, and transmits the route display picture data to the user terminal.
