ABSTRACT:
There is disclosed a navigation system adapted to support driving of a moving body such as an automotive vehicle. This navigation system determines a present position of a moving body in which the navigation system is mounted to display map information corresponding to the position of the moving body and the determined present position, and to store, as locus data, information of a route through which the moving body is advanced to display a movement route in map information. Storing of locus data is carried out by detecting a traveling azimuth to judge a change in the traveling azimuth to thereby compress locus data only to data in a predetermined range before and after the position where the azimuth is changed. Further, coordinate values in a map at the azimuth changed position and traveling azimuth data before and after the azimuth changed position are stored as locus data. In addition, locus data in an instructed collection zone are stored or preserved with respect to a plurality of zones to display a movement route through which the moving body run in the past by locus data in a designated zone thereof.
