In order to improve the concurrent access performance of WebGIS, this paper studies deficiencies of load-balancing technologies in the current WebGIS and analyzes the necessity and feasibility to solve load-balancing in WebGIS based on collaborative tasks clustering technology under the situation of large volume of concurrent accesses. A WebGIS model based on cluster scheduling load-balancing algorithm is proposed. The key is to research the cluster scheduling load-balancing algorithm. A test-bed is established. A series of test results prove that the model has good global load balancing performance.
