Abstract:Metadata that describe characteristics of geographic datasets are used to discover potential datasets and evaluate their suitability for intended purposes. Here sample maps are suggested as tools for evaluating datasets. Their usefulness in this process was studied as part of a wider research on visualization of geospatial metadata. First, design concepts were tested with twelve subjects who commented different static presentations of sample maps and multivariate visualizations. Then a prototype of an interactive metadata environment composed of sample maps, textual metadata documents, and a parallel coordinate plot was tested with eighteen subjects whose task it was to select the most suitable dataset from among six alternatives each of which represented the same theme. The subjects determined suitability within a use scenario. The prototype proved to be a valuable tool in the evaluation process, especially because multiple maps could be compared.
