Data provided by National Oceanic and Atmospheric Administration
This data set includes data collected in February and March 2000 and covers coastlines in the state of North Carolina.
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. The ATM system is a single return green laser and water returns are from the surface. A significant amount of the flight lines from this data set are over water.
