“…This basic strategy of deforming the objects in visual space has been adopted in many ways. A recent work 24 has reduced occlusion in a cityscape-like visualization of hierarchical data by deforming the bases of the 3D visual components. Similar techniques can be found in geovisualization as well.…”

Geospatial data are often visualized as 2D cartographic maps with interactive display of detail on-demand. Integration of the 2D map, which represents high level information, with the details pertaining to specific locations is a key design issue in geovisualization. Solutions include multiple linked displays around the map which can impose cognitive load on the user as the number of links goes up, and separate windowed displays on top of the map which causes occlusion of the map. In this paper, we present a self-adaptive technique which reveals hidden layers of information in single display and but minimizes occlusion of the 2D map. The proposed technique creates extra screen space by invoking controlled deformation of the 2D map. We extend our method to allow simultaneous display of multiple windows at different map locations. Since our technique is not dependent on the type of data to display, we expect it to be useful to both common users and the scientists. Case studies are provided in the paper to demonstrate the utility of the method in occlusion management and visual exploration.
