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 a portion of Levy County, Florida from 1 July - August 16 2007. This is a classified lidar data set; bare-earth points (class 2), water returns (class 9), and unclassified data (class 1). The LiDAR data was flown at a density sufficient to support a maximum final post spacing of 4 feet for unobscured areas. A footprint of this data set may be viewed in Google Earth at: ftp://ftp.csc.noaa.gov/pub/crs/beachmap/qa_docs/fl/fdem/levy/FDEM_Lidar_Levy_County.kmz The LiDAR topographic mapping survey is to support the Florida Division of Emergency Management (FDEM) development and maintenance of Regional Hurricane Evacuations Studies (RHES), which include vulnerability assessments, and to assist disaster response personnel in understanding the threats to Florida's citizens and visitors. Additional intended uses for this survey are growth management, map modernization/floodplain mapping, natural lands stewardship, and homeland security planning. A complete description of this dataset is available in the Minimum Technical Standard (MTS report) "Final Report of Specific Purpose LiDAR Survey - LiDAR, Breaklines, and Contours for Levy County, Florida" submitted to Florida Division of Emergency Management.

A visual qualitative assessment was performed in the source Lidar dataset. Lidar source compiled to meet 1m horizontal accuracy. 1 The PDS team does not perform independent horizontal accuracy testing on the LiDAR. LiDAR vendors perform calibrations on the LiDAR sensor and compare data to adjoining flight lines to ensure LiDAR meets the 1 meter horizontal accuracy standard at the 95% confidence level. The LiDAR was required to meet 0.60 feet Fundamental Vertical Accuracy (FVA) and 1.19 feet Consolidated Vertical Accuracy (CVA). 0.1768 Based on the vertical accuracy testing conducted by PDS, using NSSDA and FEMA methodology, vertical accuracy at the 95% confidence level (called Accuracyz) is computed by the formula RMSEz x 1.9600. The dataset for Levy County, Florida satisfies the criteria: Countywide lidar dataset tested 0.58 ft vertical accuracy at 95% confidence level in open terrain, based on open terrain RMSEz (0.30 ft) x 1.9600. Countywide lidar dataset tested 0.86 ft vertical accuracy at 95% confidence level in all land cover categories combined, based on consolidated RMSEz (0.44 ft) x 1.9600.

SANBORN MAP COMPANY 200805 Unknown vector digital data LiDAR Survey of Levy County, Florida, conducted in the summer of 2007 under a contract of Dewberry & Davis, LLC in support of the Florida Division of Emergency Management. online 20070701 20070816 ground condition Lidar LiDAR dataset was used to create intensity stereo pairs for 3D breakline compilation and for contour generation. The ABGPS, IMU, and raw Leica ALS-50 LiDAR data are integrated into the LEICA ALS post processor software. The resultant file is in a LAS binary file format. The LAS file version 1.1 formats 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 horizontal datum and GRS80 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 include overlap. The data was classified as follows: Class 1 = Unclassified. This class includes vegetation, buildings, noise etc. Class 2 = Ground Class 9 = Water LiDAR Point Cloud LAS 1.1 format 2008 Classified LiDAR datasets Sanborn Map Company Andrew Lucero Sr. Project Manager mailing and physical address

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 West 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. 20110824 DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce Pamela Grothe Mailing and Physical Address
