Resource Abstract:
- description: A digital elevation map (also known as a Digital Elevation Model, or DEM) of a portion of the Gateway National
Recreation Area in New Jersey and New York was produced from remotely sensed, geographically referenced elevation measurements
cooperatively by the U.S. Geological Survey (USGS), the National Park Service (NPS), and the National Aeronautics and Space
Administration (NASA). Elevation measurements were collected over the area using the NASA Experimental Advanced Airborne Research
Lidar (EAARL), a pulsed laser ranging system mounted onboard an aircraft to measure ground elevation, vegetation canopy, and
coastal topography. The system uses high-frequency laser beams directed at the Earth's surface through an 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 plane travels over the target area at approximately 50
meters per second at an elevation of approximately 300 meters. The EAARL, developed by NASA at Wallops Flight Facility in
Virginia, measures ground elevation with a vertical resolution of +/-15 centimeters. A sampling rate of 3 kilohertz or higher
results in an extremely dense spatial elevation dataset. Over 100 kilometers of coastline can be surveyed easily within a
3- to 4-hour mission. When subsequent elevation maps for an area are analyzed, they provide a useful tool to make management
decisions regarding land development. For more information on Lidar science and the Experimental Advanced Airborne Research
Lidar (EAARL) system and surveys, see http://ngom.usgs.gov/dsp/overview/index.php and http://ngom.usgs.gov/dsp/tech/eaarl/index.php
