A map information processing apparatus includes a road matching means (143) for comparing the road data with current position data to carry out map matching, an input unit (130) for inputting both a specified detection start point and a specified detection end point, an unregistered road detection means (144) to which both the specified detection start point and the specified detection end point are inputted, for detecting, as an unregistered road, a section between a detection start point and a detection end point of the unregistered road which are acquired on the basis of either the map matching carried out by the road matching means or the result of comparison between running track data and the road data, and a road data generating means (145) for generating road data corresponding to the detected unregistered road and storing the road data in a map data storage means.

A map information processing apparatus includes an intersecting determining means (20) for determining intersection points where a new road detected by a new road detecting means (19) intersects either roads included in map information or roads previously detected by a new road detecting means, other than start and end points of the new road, a road update information generating means (21) for generating road update information including information for updating new road information and road information included in the map information based on new road information about the detected new road and intersection information indicating the intersection points determined by the intersecting determining means, and a road information updating means (24) for updating the road information included in the map information based on the road update information, and for writing the new road information into a new road information storage means (16b).
摘要:
In a map information processing apparatus including a processor 5 for updating map information containing map data stored in a map information storage device 3, road network data contained in the map data stored in the map information storage device has a data structure in which the road network data is composed of link strings each of which represents a series of roads in a road network as a series of links connecting nodes, the road network being represented by the nodes and the links; each of the link strings is represented by a link string record in which link records defining the links are arranged in order of the series of the links; each link constituting the link strings is provided with an invariable link identifier proper to each link; and node indication information for designating each node included in the link strings is represented by the link identifier of the link having the node as its one end.

摘要:
A map data processing unit includes a batch update section and dynamic update section. A type of update data fed from an update data input section is decided using header information. If the update data is route search data, the batch update section collectively updates all the map data to latest version map data according to the update data from the update data input section. If the update data is not the route search data, the dynamic update section updates the map data to the latest version map data according to the update data every time the map data becomes necessary. Thus performing the collective or dynamic update according to the type of the update data enables the update to the latest map data without affecting the operation speed of a navigation function, with minimizing the time precluding the use of the navigation function.
