Link information management method
First Claim
1. A link information maintenance and management method using a server and a client coupled to said server, said method comprising the steps of:
- a) in said server, storing old area information concerning a first area including a closed area, attribute information correlated with said old area information, and old link information indicative of a correspondence relationship between said old area information and said attribute information;
b) in said client, storing new area information concerning a second area including a closed area;
c) in said client, displaying said first area and said second area in accordance with said old area information received from said server and said new area information, respectively, and obtaining position information of a predetermined number of corresponding points indicative of the same positions instructed on said first area and said second area through an input device;
d) in said server, translating said old area information by using said position information received from said client, and judging similarity between the closed area of said translated old area information and the closed area of said new area information;
e) in said server, generating new link information correlating said new area information and said attribute information based on said similarity judgment in step d) and said old link information;
f) in said client, storing said generated new link information received from said server; and
g) in said client, displaying said attribute information received from said server and said closed area on said second area by using said generated new link information.

Abstract
A link information management method is capable of reducing the number of steps of a link maintenance processing of link information indicating a correspondence relationship between geographical information in a geographical information system and attribute information. To realize the method, geographical information is compared and judged by translating first geographical information based on corresponding points judged as the same points inputted on first and second geographical information by an operator. Further, update days of link information and attribute information are compared and judged, and current link information which causes the second geographical information and the attribute information to be correlated with each other is generated based on the compared and judged results of the link information and the attribute information. Then, attribute information and a closed area on the second geographical information are displayed by using the current link information thus generated.
