In a cooperative research program, USGS, NASA and NOAA acquire laser altimetry data prior to and following extreme storms to quantify amounts of coastal change using NASA's Airborne Topographic Mapper (ATM). The ATM was developed for climate change applications involving annual surveys of the Greenland ice sheet, but is also ideal for surveying the topography of beaches. The ATM can survey hundreds of kilometers of coast in a single day with data densities that cannot be achieved with traditional survey technologies.

As the aircraft flies along the coast, a laser altimeter scans a several hundred meter swath of the earth's surface acquiring an estimate of ground elevation every few square meters. Change is quantified by comparing pre-storm to post-storm surveys. Traditional USGS topographic sheets do not have sufficient resolution to be useful for comparing coastal elevations. Airborne scanning laser surveys are providing unprecedented data to investigate the magnitude and causes of coastal changes that occur during severe storms.
