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 416 square miles in the eastern portions of Clay and Putnam Counties, Florida from August 18 - September 4, 2007.
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.
