摘　　要：随着网络技术的快速发展,SOA作为构建企业级分布式软件系统的思想和方法学,已经得到了越来越广泛的应用。本文主要探讨了如何基于SOA技术实现传统的GIS应用系统。首先,我们介绍了SOA解决的GIS系统中模块复用的两大问题:封装和组合,以及现阶段还存在的问题,如海量数据和QoS等,接着简单介绍了当前SOA在GIS中的应用情景。最后,我们通过一个小型校园GIS服务应用实例PKUMAP,详细阐述了如何利用SOA的核心技术,如SCA,BPEL来构建GIS应用系统。With the rapid development of network technologies, SOA, which is a methodology of constructing the enterprise distributed software systems, has been widely used nowadays. In this paper, we mainly discussed about how to construct a traditional GIS application with the related technologies of SOA. First, we explained the two key problems about module reuse in GIS： encapsldation and combination, and the issues which haven＇t been addressed till now. Next, we described some simple situations of applying SOA in GIS. At last, we take PKUMAP as an example, which is a light weighted web GIS application, to expound how to implement the GIS applications in detail using the kernel technologies of SOA, such as SCA, BPEL and so on.
