摘要
WebGIS作为网络技术和GIS技术的结合点，近几年在电力GIS得到了广泛的应用。Web Services的出现，彻底改变了在Web上进行软件设计的方法，也将引起了电力GIS体系的变革。本文通过对电力GIS单个事例的剖析，给出了一个基于Web Services的WebGIS三层系统构架模型，并在此基础上重点在应用服务器端的设计上，并对其进行了详细的论述，即通过应用服务器提供的Web Services向客户端提供各种服务功能。
As a combination of Internet technology and GIS technology, WebGIS has been used widely in recent years in Electric GIS. The emergence of Web Services changes the design mode and Electric GIS system. This paper analyzes a single case of Electric GIS deeply, and introduces a three tier system truss model based on Web Services technology. In the implementation of the Application Server,the Web Services implemented by Application Server is adopted to provide the various functions for client.
