It is an new research field for data retrieval based on information visualization technique. In the process of geospatial metadata retrieval, multivariate visualization will display the retrieval process, offer implicit information among data to improve the retrieval result and accuracy. First, this paper introduces three usable visualization technologies:parallel coordinates, star plots and scatter plot matrix, which based on the characteristics of data retrieval. Second, It pay more attention to the key issues:visualization technique, interactive browse, data organization and retrieval algorithm. Finally, we analyse the evaluating usability of visual retrieval for improving the design of retrieval process.
