为实现WebGIS中地理空间信息的有效管理和网络共享,结合国际地理空间信息共享的标准规范,对WebGIS中地理空间Metadata的定义、作用、内容、技术实现及其应用进行了详细的研究和设计,提出了与WebGIS集成的地理空间Metadata管理系统解决方案,并给出了体现具体技术实现的原型系统,为国家空间信息基础设施和数字地球的建设提供了理论基础和技术原型,在当今信息化与数字地球时代,对地理空间信息的网络发布和共享具有积极的推动作用和深远的社会意义.

The massive information and world-covered network makes the information management and sharing more urgent than ever, in order to attain invalid management and sharing of geospatial information on WebGIS, the detailed research and design on definition, role, content, implementation, application of geospatial metadata has been discussed in this paper. Combined with the frontier of international geospatial metadata standard, the geospatial metadata standard draft has been advanced here. Also taking advantages of the newest Internet technology and integrated with WebGIS, geospatial metadata management system, which had been running on Internet, has been designed and achieved. And some of demonstrations of various functions of this system have been presented finally. In the current times of information and Digital Earth, it will promote the sharing of geospatial information and propel the progress of Chinese standard, at the same time, this system provided the bases for constructing National Spatial Information Infrastructure (NSII) and Digital Earth.
