Popis

This data set includes data collected in 1998 to evaluate the ability of lidar to survey airport obstructions in collaboration with NOAA National Geodetic Survey. The laser emits laser beams at high frequency and is directed downward at the earth's surface through a port opening in the bottom of the aircraft's fuselage. The laser system records the time difference between emission of the laser beam and the reception of the reflected laser signal in the aircraft. The aircraft travels over the ground at approximately 60 meters per second while surveying.
