  • Geographic information output system
    Publication number: 20010027375
    Abstract: The present invention is intended to achieve optimum navigation services for moving means types corresponding to automobiles, bicycles, wheelchairs and walking. Moving means type information about a moving means type to be used by a user who desires the supply of route information is produced, and a starting position data on a starting position from which the user starts is obtained. A map of an area surrounding the starting position is extracted from map data for the moving means type and the same map is displayed. A destination to which the user desires to travel is specified, map data for the moving means type is searched for a route by using the starting position and the destination as keys for retrieval, and an optimum route for the moving means type is extracted.
