Abstract:
1. A map information processing apparatus comprising: a map information storage section for storing map information on an area by area basis formed in meshes; a positioning section for measuring its own present location; a new road detecting section for deciding that a new road is detected when the present location measured by said positioning section is on a road not included in the map information stored in said map information storage section; a new road registration section for making additional registration of the new road detected by said new road detecting section to the map information stored in said map information storage section; a route calculating section for calculating a recommended route from a predetermined search start position which is a calculation starting point used in a route calculation for confirming validity of the new road detected by the new road detecting section, to a predetermined search end position which is a calculation ending point used in the route calculation for confirming the validity of the new road by using the map information including the new road additionally registered to said map information storage section by said new road registration section; a new road registration decision section for deciding that the new road is additionally registerable to the map information stored in said map information storage section when the recommended route calculated by said route calculating section includes the new road detected by said new road detecting section; and a new road deleting section for deleting the new road that is additionally registered to said map information storage section by said new road registration section, when said new road registration decision section determines that the recommended route calculated by said route calculating section does not include the new road detected by said new road detecting section.
