| Abstract: | In order to improve the performances of GIS server in WebGIS,overcome its disadvantages of limited processing and memory resources and enhance its tolerance,the actuality and problem of traditional WebGIS are analyzed.The load-balancing technique on GIS server in WebGIS system is put forward,the least connection load-balancing algorithm is designed which is suitable to GIS server,the framework and working flow of the system are showed.Lastly the experimentation indicates that the load-balancing technique in this paper accelerates the access speed of WebGIS site and resolves single GIS server exception.It achieves the expectation of faster,better execution of WebGIS server. |
