Abstract:
A map information display system for a moving body, comprising:coordinate information generating means for generating route point coordinate information representing points on a route being traveled by the moving body and on a scheduled route; limited region map information generating means for extracting map information for only a limited region based on the route point coordinate information from map information stored in a storage medium and including road information, and for generating limited region map information, said limited region map information generating means including: route generating means for generating a moving body route based on the route point coordinate information and the road information; extracting means for setting map information of a strip-shaped region extending along the moving body route as the limited region map information; and strip-shaped region adjusting means for adjusting a size of the strip-shaped region so as to include the moving body route when it is determined that the information amount of the limited region map information is larger than a specified storage capacity but less than a storage capacity of the storage means; storage means for storing the limited region map information; and display means for displaying the stored limited region map information; wherein said extracting means includes shape selection means for selecting a shape of the search region.
