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.
