Effective Load-Balancing Framework for Distributed WebGIS

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 because of the contradiction between distributed WebGIS massive data and the limited bandwidth of network resources. Based on analysis of the two frameworks of WebGIS and the properties of intelligent agent in the field of distributed WebGIS, this paper attempts to present a hybrid model WebGIS framework. The performance of this hybrid model has been verified though the experiment for cable monitoring system conducted in state grid in Beijing. It has been proved that this framework is effective on improving the inquiry speed and maintaining a good network-load performance.
