An Effective Loading-Balancing Framework for Distributed Webgis Based on Intelligent Agent

The contradiction between Distributed WebGIS massive data and the limited bandwidth of network resources is becoming more and more serious, and the inquiry of vector data and transmission of massive data between the client and the server end has become the critical key of the problem. Based on analysis of the two frameworks of WebGIS and the properties of intelligent Agent in the field of Distributed WebGIS, this article attempts to present a hybrid model WebGIS framework. The experiment for cable monitoring system conducted in State Grid in Beijing has proved that this framework is effective on improving the inquiry speed and maintaining a good network-load performance.
