Research and Design of Geospatial Metadata Management System on WebGIS
WebGIS中地理空间Metadata 管理系统研究与设计

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.
