Summary

Description

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 is a classified lidar data set, bare-earth points (class 2), noise points (class 7), water returns (class 9), and unclassified data (class 1). Class 12 contains LiDAR points removed from the overlap region between adjacent flight lines. The LiDAR data was flown at a density sufficient to support a maximum final post spacing of 4 feet for unobscured areas. This data set is a collection of smaller project areas collected at different times in southwest Florida. Specifically, the data were collected within portions of Pinellas, Hillsborough, Manatee, Sarasota, Charlotte, Lee, Collier, Monroe, and a small portion of the coastal area of Pasco, Counties. Project Area A, also in Pasco County, is data from the Southwest Florida Water Management District (SWFWMD), collected in 2004, and was not part of the FDEM collection effort. Project Area A has been added to this FDEM southwest Florida data set. The dates of collection are: Project Area A: 2004 Project Area B: 20070706-20070810 Project Area C: 20070706-20070810 Project Area D: 20070717-20070729 Project Area E: 20070717-20070708 Project Area F: 20070618-20070806 Project Area G: 20070612-20070630, 20070702, 20070714, 20070804-20070805 Project Area H: 20070615-20070629 Lee Buy Up: 20070811-20070824 Sarasota Buy Up: 20070828-20070830 Pasco Coastal: 20080209
