摘要:
A map distribution system that implements navigation using desired map data in which the degree of reliability of information about an object, such as a road or a facility, is taken into consideration is provided. A map distribution server 1a creates distribution data including difference map data and a reliance status showing the degree of reliability of the difference map data as a reply to edit request information about an edit request made by a user, and a map information terminal 3 receives the distribution data via a communication network 2 and performs navigation according to the reliance status included in the distribution data.

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.

A location-based information intermediation method and a location-based information acquisition method are disclosed. Still further, the present invention provides the mobile communication terminal and the intermediation computer system for the method.
摘要:
In a road data frame for displaying road maps, each node/link data record describing a link corresponding to a road part includes link identification information identifying an original link, and auxiliary link identification information used for identifying a plurality of alternative links which substitute for any of the original links in the map data. In a route planning data frame for route planning, each connection record describing the interconnection of nodes also includes corresponding link identification information identifying an original link, and corresponding auxiliary link identification information used for identifying a plurality of alternative links which substitute for any of the original links in the map data. By means of identification information of the original link and auxiliary links, it is facilitated to identify the correlation among links in the road data frame and the route planning data frame having different versions.
