Geo-Visual Analytics: Requirements from a User Perspective

GeoViz: Linking Geovisualization with Spatial Analysis and Modeling, 10-11 March 2011, Hamburg, Germany

Doris Dransch and Mike Sips

“The scientific investigation of real-world phenomena in space and time has become a data-intensive science in the last decade; especially at interdisciplinary research laboratories like the German Research Centre for GeoSciences (short GFZ). Terrestrial, marine and space-based high resolution sensor systems as well as complex simulation models create massive data. For instance the TerraSAR-X and the following TanDEM-X Satellite mission launched in June 2007 have created 1.5 Petabyte data since now which would, if stored at CDs, form a stack of more than 430 m and thus, top the Eiffel Tower. New insights into phenomena in space and time are often only achieved by deriving a good understanding of relationships hidden in those vast volumes of data.”
