| 摘 要： | InternetGIS蓬勃发展使得通过网络获取空间信息成为可能。然而 ,地理数据有异构性的特点 ,这种异构性限制了用户对远程数据的获取。基于公共对象请求代理体系结构 (CORBA)并结合CORBA3.0的一些新特性对InternetGIS的通用框架进行探讨 ,以实现对异构数据的获取与互操作。

| Abstract: | The rapid development of Internet GIS makes it possible to access spatial information,however,the complex and various geodata formats limit users to transparently access the remote geodata.In this paper,we study the design of such a system based on the features provided by Common Object Request Broker Architecture (CORBA)and some novel features provided by CORBA3.0. CORBA-Based Internet GIS offers a scheme for organization and management of distributed heterogeneous geodata and realizes the accessibility interoperability of heterogenous geodata. |
