Elimination of systematic errors from airborne laser scanning data

The paper discuses the elimination of systematic errors from airborne laser scanning data. Systematic errors affect the reliability of the data as well as subsequent processes; their elimination can almost be regarded as mandatory. The paper discusses and models the errors that can be found in airborne laser scanning systems and then analyzes their effect on the reconstructed surface. Following is a presentation of an error recovery model that is based on natural surfaces. The error recovery model is then extended to cope with the adjustment of laser swaths. Some of the topics that are addressed concern the tie and control of information and their incorporation into the model and automation of the process. The paper concludes with a demonstration of the adjustment.
