Real-time Information Visualization of 3D Terrain and Georeferenced Data

    Terrain Rendering has been an important topic for many years now and research has lead to breathtaking realistic, computer-generated sceneries and by exploiting current graphics hardware, this can even be achieved in real-time. However, for many industrial fields a pure realistic terrain depiction is not sufficient, but the visualizations must be tailored to specific analysis goals. For instance, in avionic systems the visual communication of terrain topography can be used to facilitate situation awareness. In this case topographical features, such as high mountains, must be particularly emphasized and depth perception is an essential, safety-critical issue. In contrast, other application fields, for instance geology, seeks knowledge about fine-granular details of the relief and therefore a different customized presentation is required.

    Additionally, terrain models are often not contemplated in isolation, but together with geo-spatial data, such as weather information, data about infrastructures and urban areas, or intelligence about the position or trajectory of moving objects. Besides spatial reference most of those data have also temporal references. Developing suitable representations for this in many cases large and complex data is a challenging topic. Among the problems are the limited number of presentable and intuitively perceivable information units, adherence to expressiveness and the avoidance of errors, which is most important in safety-related environments. Finally, the terrain representation and the data representation must be carefully blended to minimize interferences.

    The aim of my research is the the design and realization of representations tailored to 3D terrain and geo-spatial data analysis. To this end, I am interested in developing scalable visualizations that can be tuned to different hardware, software and user requirements.
