The project area is located in the southeastern part of Florida, in parts of the counties surrounding Lake Okeechobee. LiDAR was collected over approximately 2289 square miles in parts of the following counties: Broward, Glades, Hendry, Highlands, Martin, Okeechobee, and Palm Beach. The maximum point spacing is 4 ft in unobscured areas. This data set is a classified data set and has a classification for sugar cane. To produce accurate, high-resolution data for planning and analysis to support the Florida Division of Emergency Management (FDEM) development and maintenance of regional evacuation studies, which include vulnerability assessments and to assist disaster response personnel in understanding threats to Florida's citizens and visitors.

A visual qualitative assessment was performed to ensure data completeness. Horizontal accuracy meets or exceeds 3.8 feet at the 95% confidence level using RMSE(r) x 1.7308 as defined by the FGDC Geospatial Positional Accuracy Standards, Part 3: NSSDA. 1.16 This was for the entire HHD project. A complete assessment of the vertical accuracy is available in the Minimum Technical Standard (MTS report) "Final Report of Specific Purpose LiDAR Survey-LiDAR-Generated Breaklines and Contours" submitted to Florida Division of Emergency Management. You may view this document at: ftp://ftp.csc.noaa.gov/pub/crs/beachmap/qa_docs/fl/fdem/herbert_hoover_dike/FMTS_HHD.pdf .0914 This value exceeds the NSSDA standard for one-foot (1') interval contours.

The resultant file is in a LAS binary file format. The LAS file version 1.1 format can be easily transferred from one file format to another. It is a binary file format that maintains information specific to the LiDAR data (return#, intensity value, xyz, etc.). The resultant points are produced in the geodetic coordinates referenced to the NAD83 HARN horizontal datum and NAVD88 vertical datum. The date and time for each flight line can be determined using the Julian date and time. The Julian date is a continuous count of days and fractions since noon Universal Time on January 1, 4713 BCE on the Julian calendar.

A combination of proprietary filters are applied as appropriate for the production of bare earth digital terrain models (dtms). Interactive editing methods are applied to those areas where it is inappropriate or impossible to use the feature extraction filters, based upon the design criteria and/or limitations of the relevant filters. These same feature extraction filters are used to produce elevation height surfaces. The LiDAR mass points were delivered in American Society for Photogrammetry and Remote Sensing LAS 1.1 format. The header file for each dataset is complete as defined by the LAS 1.1 specification. In addition the following fields are included: Flight Date Julian, Year, and Class. The LAS files do not contain overlap (class 12). The data was classified as follows: Class 1 = Unclassified. This class includes vegetation, buildings, etc. Class 2 = Ground Class 3 = Sugarcane (Job specific classification, not used in contour generation) Class 7 = Noise Class 9 = Water Class 12 = Overlap Sugarcane points (class 3) were added to this project at the request of the US Army Corps of Engineers. The lidar sensor could not adequately penetrate sugarcane fields. A method was developed to define the location of sugarcane. Points inside of the sugar_cane feature class in the HHD geodatabase were either classified as unclassified (class = 1) or sugarcane (class = 3). There are no ground (class = 2) points inside of the sugar_cane feature class.

The files contained LiDAR intensity and elevation measurements. CSC performed the following processing on the data to make it available within Digital Coast: 1. The data were converted from State Plane Florida East coordinates to geographic coordinates. 2. The data were converted from NAVD88 heights to ellipsoid heights using Geoid03. 3. The LAS header fields were sorted by latitude and updated. 2010 Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Coastal Services Center (CSC) CEM Project Scientist mailing and physical

Charleston SC 29405 US 843-740-1200 tcm@csc.noaa.gov The NOAA National Geophysical Data Center (NGDC) received Lidar data files by ftp. The data received compressed containing LiDAR data from the NOAA Coastal Services Center. The data are currently being served via Digital Coastl at http://www.csc.noaa.gov/digitalcoast/. The data can be used to re-populate the system. The data are provided in LAS format. LAS format is an industry standard for serving LiDAR data. The data are exclusively in geographic coordinates, however, the datums used vary. Most are NAD 83, however some are in ITRF. Vertical systems include both ellipsoid (ITRF and NAD 83) and NAVD 88. For NAVD 88 values, Geiod 03 is primarily used; however, data received in NAVD 88 prior to 2003 was processed using Geoid 99. 20110907 DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce Pamela Grothe Mailing and Physical Address
