An objective of the present invention is to provide a map information processing device with which it is possible to generate connection information with a link and a node even if a link exists which bridges meshes.
A map information processing device includes: a map information storage unit (111) for storing hierarchical map information; an additional update hierarchy decision processing unit (118) for deicing at least one hierarchy for additionally updating a unregistered road detected by a travel; and an unregistered road add/update unit (117) which adds/updates an unregistered road to the map information storage unit for the hierarchy decided by the add/update hierarchy decision processing unit.
A map information processing device selects shape coordinate information corresponding to one of buildings or land sections out of a plurality of buildings or land sections, identifies the road link closest to the building or land section corresponding to the shape coordinate information according to the selected shape coordinate information, acquires house number range information contained in the road link information corresponding to the identified road link, calculates, according to the acquired house number range information, the house number at the point at which the vertical line drawn from a predetermined point on the contour or within the contour of the planar outer shape of the building or land section represented by the selected shape coordinate information to the identified road link crosses the road link, and determines a house number which is to be given to the selected shape coordinate information on the basis of the calculated house number.
A map information processing device according to the present invention comprises: a map information storage means for including in map information road path net data having connection link information including mesh information which defines a road path net with a node and a link which are disposed in a mesh and information of a link which is connected to the node and to which the link is associated, and storing same for each mesh; and a link terminal node information computation means for computing, based on the road path net data connection link information which is acquired with the road path net data acquisition means, from the connection link information of the mesh road path net data if a link does not bridge meshes, or from the connection link information of the road path net data of two meshes in which nodes at both ends of the link are included if the link does bridge meshes, link terminal node information which is information of the node which is connected to the end part of the link.

A map information processing device comprises a map information storage section (23) which stores map information, a sensor information input section (22) which inputs sensor information for use in calculation of current position, a navigation processing section (25) which creates a map image with such a display scale that the overall shape of a tunnel is confined within one screen when it is judged that the current position indicates the entry of a vehicle into a tunnel based on the map information which is read from the map information storage section and a current position which is calculated by use of the sensor information inputted from the sensor information input section, and an output control section (26) which outputs the map image created by the navigation processing section.
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.
A map information processing device has map information storage means (16a) that stores map information including road information; new road detection means (19) that detects a new road that is a road in which a road corresponding to the position of the device, detected by position detection means (15), is not present in the road information included in the map information; intersection judgment means (20) that judges an intersection waypoint that is a point other than start and final points and at which point the detected new road and a road included in the map information or a road detected in the past by the new road detection means cross; road update information production means (21) that, based on the new road information and intersection information representing the intersection waypoint judged by the intersection determination means, produces road update information including information for updating the road information included in the new road information and map information; and road information update means (24) that, based on the road update information, updates the road information included in the map information and writes the new road information in the new road information storage means (16b).
