| 摘 要： | 现代信息技术的变革使网络技术与GIS的结合日益紧密 ,从而促进了开放GIS技术的研究。开放式GIS研究的目的是提供一套具有开放界面规范的通用组件 ,开发者根据这些规范开发出交互式组件 ,从而实现不同种类地理数据和地理处理方法间的透明访问。文中主要讨论了基于CORBA的开放式GIS的网络系统构建技术 ,使用户能在分布式的多服务器且存在异构的网络环境中共享地理空间数据。

| Abstract: | As the information technologies evolute and the system integeration is implemented widely,we need to share the geospatial information in order to diffuse the usability of GIS.The purpose of studying open GIS is to provide a set of general models with specification of open interface. Based on the specification developer can develop interactive models to access various kinds of geospatial data with different methods. In this paper ,we discuss the technique of constructing open object system based on CORBA to share the geospatial datum. This model consists of the distributed GIS server and client ,access manager based on CORBA to distribute the geospatial datum. |
