Abstract

Disclosed is a system for preparing a route end node series which is equipped with a route search means 7 for preparing a node series, an intersection series or a combination of both as the data series for navigation, and a route end node series preparing means 3 for preparing the node series from the starting point and the destination to the respective nearest particular points. The route end node series preparing means 3 prepares node series by successively performing node search until the node nearest to the point indicated by the positional information on the starting point or the destination is attained. This construction makes it possible to perform course guidance through navigation based upon the node series between the starting point or the destination and the nearest intersection thereto even if the starting point or the destination is set at a point between intersections when particular points are set as intersections.
