| 摘 要： | Ｉｎｔｅｒｎｅｔ ＧＩＳ的蓬勃发展使得通过网络获取空间信息成为可能，然而，由于地理数据格式的多样性（异构数据），限制了用户透明的获取远程数据以下对不同历史时期、不同格式、不同存在形式的数据用户端无缝的操作与表现。提出了Ｉｎｔｅｒｎｅｔ环境下基于浏览器／服务器结构交互的服务器端虚拟ＤＢＭＳ听概念，以对终端分布式异构数据库组织、管理，以及实现异构数据获取与互操作。

| 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 remote geodata and seamlessly process differently historical, different data format in enduser side. The paper brings up the concept of virtual DBMS in server side for organization and management of distributed heterogeneous database and finishment of heterogeneous geodata access and interoperability. By VGDBMS, users can acess and process geoinformation being in different locations. Finally, as an aplication example of Internet GIS GeoSurf, based on Java, crossplatform, distributed computing and browser/server, is represented in support of above mentioned issues. |
