In 2008, because the final lidar dataset satisfied the accuracy requirements in the FDEM Baseline Specifications, the lidar data was processed into .LAS files, and breaklines and contours were generated for the Florida Division of Emergency Management (FDEM) using the existing lidar data from 2004. Used in conjunction with breaklines to determine a DTM surface. The DTM was developed to support the Florida Division of Emergency Management (FDEM) development and maintenance of Regional Evacuation Studies (Study), which include vulnerability assessments and assist disaster response personnel in understanding threats to Florida's citizens and visitors.

A visual qualitative assessment was performed in the source Lidar dataset. The 3D breaklines inherit the accuracy of the Lidar it was acquired from. Lidar source was compiled to meet 1 m 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 3D breaklines inherit the accuracy of the Lidar it was acquired from. 0.18 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 Flagler County, Florida satisfies the criteria: Countywide lidar dataset tested 0.18 m(0.60 ft) vertical accuracy at 95% confidence level in open terrain, based on open terrain RMSEz 0.31 ft) x 1.9600. Countywide lidar dataset tested 0.27 m (0.88 ft) vertical accuracy at 95% confidence level in all land cover categories combined, based on consolidated RMSEz (0.45 ft) x 1.9600.

The ABGPS, IMU, and raw Leica ALS40 LiDAR data are integrated with Leica's Incorporated ALS Post Processor software. 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.

The unedited data are classified to facilitate the application of the appropriate feature extraction filters. 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 define 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 Doug Jacoby Merrick & Co Project Manager mailing and physical

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. 20110427 DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce Pamela Grothe Mailing and Physical Address
