Geo-spatial metadata visualization retrieval based on parallel coordinates

Geo-spatial metadata are abstract,complex and multi-dimension.Traditional representation method of geo-spatial metadata cannot provide effective cognition because of single display mode,limited display dimension.In order to increase the efficiency of geo-spatial metadata retrieval,the parallel coordinates of information visualization are used.And the display and interactive mode of parallel coordinates used in geo-spatial metadata visualization retrieval are discussed.At last,this paper presents the design and implementation of geospatial metadata retrieval visualization prototype system based on parallel coordinates.And the method's feasibility is validated in the prototype system.
