| Abstract: | First, combined with the techniques and characteristics of information visualization, single variate and multivariate geospatial metadata visualization are studied. Second, a design process and logical model is established of geospatial metadata visualization, and the main influence factors of visualization design and application of visualization technology are analyzed with two interact ways of designing. Then the key techniques of geospatial metadata visualization are studied, including multi-level organization and display of data, acquisition of associated attributes based on spatial features and visualization mapping of metadata. Finally through the experiment of prototype system, effectiveness of the visualization patterns is proved. |
