This Light Detection and Ranging (LiDAR) LAS dataset is a topographic survey conducted
for a coalition of GIS practitioners, including the Florida Division of Emergency
Management (FDEM), Florida Water Management Districts, Florida Fish and Wildlife Conservation
Commission, Florida Department of Environmental Protection, Army Corps of Engineers
Jacksonville District, and other state and federal agencies. The goal for this project
is to use the LiDAR data as new elevation inputs for updated SLOSH data grids. The
ultimate result is the update of the Regional Hurricane Evacuation Studies (RHES)
for the state. The State of Florida Division of Emergency Management LiDAR Survey
was collected under the guidance of a Professional Mapper/Surveyor. Data were collected
for 1019 square miles (includes the FDEM extent and the buy up area) within Brevard
County, Florida from Sept 15, 2007 to Jan 16, 2008. This is a classified lidar data
set. The data are classified: 1 = Unclassified, 2 = Ground (Bare Earth), 7 = Noise
and 9 = Water. The FDEM Baseline Specifications required a maximum post spacing of
4 feet, however, the PDS (Program and Data Solutions) team required a much higher
point density of its subcontractors in order to increase the probability of penetrating
dense foliage during the mandated summer acquisition; with nominal post spacing of
0.7 meters per flight line and 50% sidelap between flight lines, the average point
density is 4 points per square meter.
