Global Land Cover Information Sharing Based on CSW

doi:10.13474/j.cnki.11-2246.2017.0016

Abstract

Abstract: Metadata is one of the important technologies of information sharing. The information of land cover has the characteristics of diverse types, complex processing and fast change. There is no corresponding metadata standard specification until now. The characteristics of land cover information are analyzed in this paper. The existing GIS metadata standard is extended, and the global land cover information metadata model is constructed based on above. Combined with CSG specification of OGC, the global land cover metadata directory service sharing program is presented. At last, the prototype system of global land cover information metadata catalog is implemented, which provides users with the ability to discover, publish and manage metadata, and promotes the sharing of global land cover information.

Key words: land cover, metadata, specification of CSW, service, data sharing
