在分析国内外不同机构和组织拟订的元数据标准基础上,提出了一种适合中国中小城市基础地理信息集成的元数据标准,对元数据库的结构进行了设计,并用xML文档的方法开发了元数据平台,实现了元数据的管理和发布。该平台在扬州经济开发区基础地理信息平台建设中发挥了核心作用,在其支持下实现了海量地理信息数据的无缝集成和应用服务。

Development of a Metadata System for Fundamental Urban GIS Framework
Abstract:

Through analysis of metadata standards from home and abroad,a metadata standard system for middle and small cities is suggested,it's suitable for the building of fundamental urban GIS frameworks.The structure of the metadata database is designed,and a metadata system is developed with XML,so that the metadata can be managed and published.The metadata system has been successfully applied in building the fundamental GIS framework of Yangzhou Economic Development Region,and large volumes of spatial data has been seamlessly integrated to provide data service with the help of this system.
