TOWARD USABLE SPATIAL INFORMATION Werner Kuhn Andrew U. Frank Technical University Vienna, Dept. of Geoinformation Gusshausstrasse 27-29/127, A-1040 Wien, Austria Invited Paper (Extended Abstract) KEY WORDS: Open GIS, Data, Users, Usability, Economy, Standards ABSTRACT Spatial data are being collected at an increasing pace, with photogrammetry and remote sensing serving as the most productive data collecting disciplines. At the same time, markets for spatial information are emerging world-wide. Still too often, however, there is a mismatch between the demand and supply of spatial information: data being collected and offered sometimes do not meet the expectations of potential buyers. The malfunctioning of spatial data markets has many reasons, ranging from the fact that users are often unaware of existing data to the difficulties in interpreting and processing spatial data once they have been bought, to institutional and legal obstacles. A major technical reason is the lacking usability of data collections. The presentation addresses the issue of usability and discusses the widely proposed remedy of metadata. It concludes that the most effective step toward usable spatial data is not to document data collections, but to modularise them into small manageable units and packaging them with suitable operations. This vision of future spatial information services is currently being pursued under the heading of “Open GIS”. I. MARKET CONCERNS FOR SPATIAL DATA . what can | charge ?
