Expertise/Technical Approach Applications • Perimeter Surveillance of Large Harbor • To detect threat objects on large cargo vessels • Other Potential applications: • Digital Terrain Representation, Flight Simulators Interactive Graphics, City Planning • Digital terrain modeling is a powerful tool in GIS analysis and visualization. • Land-use modeling (e.g., slope stability, forest fires, agricultural production) • Collection of Satellite Maps like doqq and dem from aerial image providers and USGS. • Image Mosaicing: Doqq and dem are mosaiced to generate a single image using software’s like ENVI and Panorama factory. • Digital Terrain Model: By draping the mosaiced doqq on dem the digital 3D terrain model is created. • Hybrid 3D Model: Synthetic 3D models were fused on the terrain model using the software 3D Studio Max to generate hybrid 3D model of the areas of interest. • Levels of Detail: Each synthetic models placed on the terrain models are placed at different levels of detail.
