ABSTRACT:
An aerial survey method to determine ground contours establishes a reference plane to which all contour measurements are referred. The reference plane intersects a rotating beam optical radar unit which includes a receiving antenna. The antenna receives signal waves emanating from the aircraft to measure the relative height of the aircraft with respect to the reference plane. A survey track along the ground for the aircraft is determined and the position of the aircraft along the track is continuously measured. The aircraft is flown continuously along the track and repeated altitude measurements of the aircraft are made. The relative height of the aircraft with respect to the reference plane, the altitude of the aircraft above the ground and the position of the aircraft along the survey track are correlated to determine the ground contours.
