The new generation of space borne SAR sensors provides geometric resolution of one meter, airborne systems even higher. In this high resolution data many features of urban objects become visible, which were beyond the scope of radar remote sensing only a few years ago. Focusing on elevated objects (e.g., urban area), layover, and occlusion issues inevitably arise because of the side-looking SAR sensor principle. In order to support interpretation, SAR data are often analyzed using additional information provided by maps or other remote sensing imagery. The focus of this paper is on building extraction in urban scenes by means of combined InSAR data and optical aerial imagery

Imaging sensor systems are inevitable components of intelligent and automated machinery. Imaging sensor systems based on the laser radar (ladar) principle are proposed to provide advanced machine capabilities such as collision avoidance , obstacle detection, object recognition and position determination . This paper describes the adaption of a 3-d ladar camera to the requirements of a large computer -assisted telemanipulator (CAT) for aircraft washing.
