Basic geographic information linkage updating method and system based on cloud platform

The invention discloses a basic geographic information linkage updating method and system based on a cloud platform, and relates to the technical field of geographic information.The basic geographic information linkage updating method and system based on the cloud platform are technically characterized in that geographic elements are extracted from basic geographic information data, entity objectification processing is carried out, a network topology structure is formed according to the space relation between entity objects, and the network topology structure is updated; the method comprises the following steps: calculating global connection weights of nodes in a whole network, combining activeness indexes of the nodes, calculating node value indexes of the nodes, carrying out descending sorting according to the node value indexes, sequentially updating according to a sequence, querying whether other to-be-updated nodes are connected with a current node or not in a node updating process, and updating the node
