Resource Abstract:
- description: A seamless (bare-earth and submerged) elevation map (also known as a Digital Elevation Model, or DEM) of a portion
of western Florida, post-Hurricane Charley, was produced from remotely sensed, geographically referenced elevation measurements
cooperatively by the U.S. Geological Survey (USGS) 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.
