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.
