Resource Abstract:
- description: Binary point-cloud data of a portion of the submerged environs of Fort Lauderdale, Florida, were produced from
remotely sensed, geographically referenced elevation measurements by the U.S. Geological Survey (USGS). Elevation measurements
were collected over the area using the second-generation Experimental Advanced Airborne Research Lidar (EAARL-B), 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 pulse 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 0.5-1.6
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 peak sampling rate of 15-30 kilohertz
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: Binary point-cloud data of a portion of the submerged environs of Fort Lauderdale,
