摘　　要：传统的GIS由于未能解决好客户端和服务器端的负载平衡问题,大大限制了其使用范围。基于B/S模式的分布式Web GIS能够很好地平衡两端的负载进而更好地发挥服务器和客户端的性能。通过介绍ASP及其组件,分析Web GIS的总体架构,探讨了采用3层体系结构的Web GIS实现技术,在Web服务器端采用组件技术,用ASP实现客户端浏览界面。Traditional GIS cann't Solve the problem of the load balance between the client side and the server,so it restricted the area of its application.The distributed Web GIS pattern based on B/S can solve the load balance between them perfectly,and it can exert the capability of the client side and the server much better.In this paper,with the introduction of ASP and its components,the general structure of Web GIS is analyzed,technology of WebGIS based on three-layer architecture is discussed,and browse of client by ASP is realized by applying technology of components in Web server.
