Resource Abstract:
- description: ASCII XYZ point cloud data were produced from remotely sensed, geographically referenced elevation measurements
by the U.S. Geological Survey (USGS). Elevation measurements were collected over northwest Florida, post-Hurricane Katrina
(August 2005 hurricane), using the National Aeronautics and Space Administration (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 60
meters per second at an elevation of approximately 300 meters, resulting in a laser swath of approximately 240 meters with
an average point spacing of 2-3 meters. The EAARL, developed originally by NASA at Wallops Flight Facility in Virginia, measures
ground elevation with a vertical resolution of 3 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
resultant elevation maps for an area are analyzed, they provide a useful tool to make management decisions regarding land
development.; abstract: ASCII XYZ point cloud data were produced from remotely sensed, geographically referenced elevation
