Summary
Description
This data set includes data collected during Fall 2000 and covers coastlines of the states of Maryland, New Jersey, New York, Connecticut, Rhode Island, Massachusetts, New Hampshire, and Maine. Laser beach mapping uses a pulsed laser ranging system mounted onboard an aircraft to measure ground elevation and coastal topography. 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 beach at approximately 60 meters per second while surveying from the low water line to the landward base of the sand dunes.
