Purpose
|
|
This lidar-derived submarine topography map was produced as a collaborative
|
|
effort between the U.S. Geological Survey
|
|
(USGS) Coastal and Marine Geology Program, National Park Service (NPS) South Florida/Caribbean Network Inventory and
|
|
Monitoring Program, and the National Aeronautics and Space Administration (NASA) Wallops Flight Facility. One objective of this
|
|
research is to create techniques to survey coral reefs for the purposes of habitat mapping, ecological monitoring, change detection,
|
|
and event assessment (for example: bleaching, hurricanes, disease outbreaks, and so on). As part of this project, data from an
|
|
innovative instrument under development at the NASA Wallops Flight Facility, the NASA Experimental Airborne Advanced Research
|
|
Lidar (EAARL) are being used. This sensor has the potential to make significant contributions in this realm for measuring water depth
|
|
and conducting cross-environment surveys. High spectral resolution, water-column correction, and low costs were found to be key
|
|
factors in providing accurate and affordable imagery to managers of coastal tropical habitats.

|
Information to be Derived
|
|
The laser soundings used to create this map
|
|
were collected during September 2001 and August 2002 by the NASA EAARL
|
|
system mounted on a Cessna 310 aircraft. The EAARL uses a 'waveform-resolving' green laser capable of mapping submarine and subaerial
|
|
(land) topography in a single overflight. The EAARL system is typically flown
|
|
at 300 m altitude AGL, resulting in a 240 m swath
|
|
for each flightline. Data collection occurred with approximately 50 percent
|
|
overlap between flightlines, resulting in about one laser
|
|
sounding per square meter. The data were processed by the USGS Center for
|
|
Coastal and Watershed Studies to produce
|
|
1-meter resolution raster images that can be easily ingested into a Geographic
|
|
Information System (GIS). The data were
|
|
organized as 2 km by 2 km data tiles in 32-bit floating-point integer GeoTiff
|
|
format. Contour line and hillshade layers were
|
|
generated from the lidar data tile and incorporated into this map product.
