摘要

The object of the present invention is to provide a map information processing apparatus that is capable of minimizing the amount of update data by setting affected areas of new roads when performing maintenance of a server apparatus for new road information, and by selecting roads that affect route calculation when the result of a route calculation is within an affected area, updates only selected roads in object units. The map information processing apparatus of the present invention sets an update effective range for a new road, and when part or all of the result of a route search by a navigation apparatus overlaps the update effective range, transmits additional map information related to the new road to the navigation apparatus. The navigation apparatus stores the additional map information and performs a route search based on map information to which the additional map information has been added.
