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 a portion of the Texas coastline, post-Hurricane
Rita (September 2005 hurricane), using the 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 the National Aeronautics and Space Administration (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.;
