3D Terrain Visualization of GIS Data for Analysis

3D terrain visualization of geographic information systems (GIS) data has become an important issue in recent years. The availability of 3D representation tools has increased the demand for 3D terrain visualization. The evaluation of remote sensing data from multiple sensors is complicated by different image scales and orientations. Thus a simultaneous visualization of the multi-sensor data is envisaged. For a spatial impression of the observed area the images are co-registered, projected onto a 3D terrain model and displayed stereoscopically. The presented 3D evaluation system allows the real-time navigation in the virtual landscape. The user is able to manipulate the 3D model by blending and mosaicking the images from different sensors in which geo-information system (GIS) offers the possibility to display GIS data.
