基于元数据管理的环境地理信息系统的开发研究

Metadata Management Environment Based on Geographic Information System Development

基于元数据管理的环境地理信息系统充分运用元数据管理理论进行系统开发,建立开放式的系统架构,形成了环境地理信息系统综合运用平台框架。该系统把元数据作为系统的核心数据内容,其最重要的技术特点是通过对元数据的自定义来实现数据的扩展性。

Metadata management environment based on geographic information systems is make full use of metadata management theory to system development.It establish an open system architecture and create a comprehensive application of environmental geographic information system platform framework.The system is the metadata as the system core data content,and the important technical features is to accomplish the data extensibility by metadata definition.
