| Abstract: | With the development of GIS and with the improved apparatus,spatial data are used more and morewidely in many fields.The extraordinary feature of spatial data is its plenty of information.So it is necessary tofigure a quick and effective way to manage the metadata of spatial data.Spatial metadata includes the content,quality,identifier,coordinate system,and format of spatial data.It somewhat is regarded as the index of spatialdatasets.According to the Metadata Standards of NFGIS(National Fundamental of GIS)drafted by NationalCenter of GIS,this paper discusses how to manage metadata of spatial information and build Oracle Database.Taking Ningbo GIS as an example,the building flow and architecture of spatial metadata management systemwas introduced.The study showed that spatial metadata management system can help to manage metadata morequickly' and efficiently,thus meeting the social requirement for spatial geographical data to the fullest extent. |
