Support of workflow tracking in exploratory spatial data analysis systems

Present systems for visual analysis of geographical and statistical information allow users to gain quick overview of large spatial datasets with the help of numerous graphical tools. For successful utilization of these techniques, presentations that led the user to understanding should be preserved to mark the stages of analysis. Parameters of the visualization methods that generated the presentation are used for storage since they are compact and can be utilized to recreate the same visual representation later. Flexible selection of visual displays for saving allows preservation of the complete system state or fine grained views storing specific users? findings.
