MAO INFORMATION PROCESSING DEVICE

摘要

A map information processing device has a map information storage means (16) for storing map information for each of the regions of a mesh-like pattern; a positioning means (15) for measuring the current position of a user; a new road detection means (19) for detecting that, when the current position measured by the positioning means is on a road not included in map information stored in the map information storage means, the road is a new road; a new road registration determination means (20) for determining that, when road density of a region in which the new road detected by the new road detection means is included is a predetermined value or below, the new road can be added and registered in the map information stored in the map information storage means; and a new road registration means (21) for adding and registering the new road that has been determined, by the new road registration determination means, that it can be added and registered in the map information stored in the map information storage means.
