Method for evaluating the suitability of a piece of land for a landing zone or taxi surface for airplanes

摘要

The method involves producing three-dimensional (3D) data for the ground area in a radar-based or laser-based 3D sensor. The measured value density of the 3D data and statistical property of the three-dimensional data is determined. A measure of the local roughness of the ground area is produced based on the measured-value density and the statistical property. The individual area elements of the ground area are classified on the basis of the roughness values produced according to the degree of suitability of area elements (FEu) as a landing area or taxi area.
