The Research and Realization of Aggregation Algorithm for Aggregating Topological Nodes based on Web GIS in Network Management

摘要

With the rapid development of GIS, it is applied to network management gradually. We can get the distributed trend of the topological nodes and the topology relation between each other through GIS. In order to reflect the topology relation when we change the zoom level of the map, it is a critical problem that how to realize a large numbers of topological nodes be aggregated quickly and accurately. In view of this situation, this paper introduced two common aggregation algorithms firstly, and then proposed an aggregation algorithm for aggregating the topological nodes in GIS with the advantages of hierarchical clustering algorithm. The paper also explained the basic idea and realization of the aggregation algorithm. The experiment results show that the algorithm provides an effective solution for aggregating topological nodes.
