Geographic information output system
First Claim
1. A geographic information output system comprising:
- a moving means type identifying device for identifying a moving means type of a moving means to be used by a user who desires the supply of geographic information;
a position determining device for determining a geographic position of the user;
a geographic information extracting device for extracting geographic information associated with the moving means type identified by the moving means type identifying device about the position of the user determined by the position determining device from a geographic database; and
an output device for providing the extracted geographic information.

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.
