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. This data was collected for Gulf County, Florida during 9 - 22 July 2007 and covers approximately 650 square miles. This is a classified lidar data set; unclassified data (class 1), bare-earth points (class 2), and water returns (class 9). The LiDAR data was flown at a density sufficient to support a maximum final post spacing of 4 feet for unobscured areas.
