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, and Monroe. In the original project 2 sections of Pasco county were used: data collection in 2004 as well as a small coastal section in 2008. These have been removed and designated as individual projects named 2004 Pasco - Classified and 2008 Coastal Pasco respectively. The dates of collection are: 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 A graphic of the footprint of the project areas may be accessed at: ftp://coast.noaa.gov/pub/DigitalCoast/lidar1_z/geoid12a/data/529/supplemental/fdem_sw.tif A shapefile of the footprint of the project areas may be downloaded at: ftp://coast.noaa.gov/pub/DigitalCoast/lidar1_z/geoid12a/data/529/supplemental/fdem_sw.zip A footprint of this entire FDEM southwest Florida project area may be viewed in Google Earth at: ftp://coast.noaa.gov/pub/DigitalCoast/lidar1_z/geoid12a/data/529/supplemental/FDEM_Lidar_Southwest_Florida.kmz
