Abstract

Due to upcoming new data driven technologies in the aviation the impact of digital terrain data is growing conspicuously. Especially for ground near operations reliable terrain information is necessarily demanded. Based on modern earth observation technologies a new generation of elevation data is obtainable. However it shall be analysed how far data derived from remote sensing techniques like INSAR or LIDAR can be applied for aviation purposes. Formerly terrain data were represented in relation to the bare earth to obtain a "Digital Terrain Model" (DTM). For aviation purposes a "Digital Surface Model" (DSM) representing the real surface of the earth including all cover like vegetation and buildings is recommended. Due to the characteristics of active remote sensors the derived model always describes an in between of the two elevation representations. To satisfy the special requirements the Institute of Flight Systems and Automatic Control (FSR) at the Technische Universitaet Darmstadt is dealing with the determination of the influencing factors which affect the quality of the terrain models being appropriate to be used as a DSM. In order to enhance the integrity of the data a "safety buffer" is created to allow the applicability for dedicated applications (figure 1).
