Research and Design of Geospatial Metadata Management System on WebGIS[J]. Journal of Image and Graphics, 2000, 5(10): 811. DOI: 10.11834/jig.20001002.
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.
