Abstract

in order to meet the requirements of massive data processing and high quality of service, a WebGiS(Web Geographic information System) cluster system has been developed which has the capability of balancing resources between servers. This cluster system includes three parts: a load balancer, a GiS server cluster, and a database of spatial and geographic information. The strategy of dynamic dispatch and the algorithm of adaptive load balancing service are presented in the paper.
