2006 USGS/NPS/NASA Experimental Advanced Airborne Research Lidar (EAARL):
Jean Lafitte National Historical Park and Preserve
|
A first surface/bare earth elevation map (also known as a Digital Elevation
Model, or DEM) of the Jean Lafitte National Historical Park and Preserve in Louisiana
was produced from remotely sensed, geographically referenced elevation measurements
cooperatively by the U.S. Geological Survey (USGS), the National Park Service (NPS),
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 easily surveyed 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.

Lidar Use Limitation |
These data depict the elevations at the time of the survey and are only
accurate for that time. Users should be aware that temporal changes may
have occurred since this data set was collected and some parts of this data may no
longer represent actual surface conditions. Users should not use this data
for critical applications without a full awareness of its limitations. Any conclusions
drawn from analysis of this information are not the responsibility of NOAA
or any of its partners. These data are NOT to be used for navigational purposes.

The data are collected using a Cessna 310 aircraft. The NASA Experimental
Advanced Airborne Research Lidar (EAARL) laser scanner collects the data using a green
(532-nm) raster scanning laser while a digital camera acquires a visual record of
the flight. The data are stored on hard drives and archived at the U.S. Geological
Survey, FISC office in St. Petersburg, FL, and the NASA office at Wallops Flight Facility
in Virginia. The navigational data are processed at Wallops Flight Facility. The navigational
and raw data are then downloaded into the Advanced Lidar Processing System (ALPS).
Data are converted from units of time to x,y,z points for elevation. The derived surface
data can then be converted into raster data (GeoTIFFs).

The NOAA Coastal Services Center received the data in LAS format.
The files contained Lidar elevation and intensity measurements. The data were projected
in UTM coordinates (NAD83; Zone 15N) and referenced to the North American Vertical
Datum of 1988 (NAVD88) using the Geoid03 model. The following processes were performed
to make the data available within the Digital Coast: 1. The data were converted from
UTM (NAD83; Zone 15N) to geographic coordinates (NAD83). 2. The data were converted
from NAVD88 (orthometric) heights to GRS80 (ellipsoidal) heights using the Geoid03
model. 3. The data were reclassified to reflect a bare earth surface (class 0 to class
2). 4. The LAS data were sorted by latitude and the headers were updated.
