摘要： 针对传统OGC GIS服务中无法保存操作状态以及参数重复传送造成服务性能不高及不同GIS服务之间相互独立的问题，结合网格技术以及网络服务资源框架规范改进OGC GIS服务，并以开源的网格工具包Globus及开源的地图服务器Geoserver为基础，设计与实现了一个改进的网络地图图像服务原型系统，通过该原型系统说明了如何改进OGIS服务以获得更高的服务集成的方法。

Abstract: To implement the complex spatial functions, many different GIS services need to cooperate and be integrated together. Due to the current OGC GIS service can not store the state information and need to send the same parameters repeatedly, the performance of it is relatively low. It also leads to the independent problem among these services. Aiming at these questions, the paper illustrates a method to improve the OGIS service according to the requirement of grid computing and WSRF. And it designs and implements a prototype grid map service system using the open source grid toolkit-Globus and Geoserver. Through the process, it illustrates how to improve the existing OGIS service to get more flexible data sharing and integration through making it grid enabled.
