In this thesis, the use of airborne laser scanning (ALS) and an automatic change detection procedure are proposed to support the monitoring of urban areas. The acquisition of reference data with an oblique forward-looking laser scanner is combined with an object-based data analysis, a coregistration of overlapping point clouds, and the boresight calibration of the ALS system. A new framework for comparison of ALS data is presented which is divided into online segmentation, terrain-referenced navigation, and the identification of conflicting information along the laser pulse propagation path.
