These data were produced for Dewberry and Davis LLC. The Escambia County LiDAR Survey project area consists of approximately 803 square miles. The LiDAR point cloud was flown at a density sufficient to support a maximum final post spacing of 6 feet for unobscured areas. Land Air mapping acquired 110 flightlines between June 21, 2006 and July 18, 2006. The data was divided into 5000' by 5000' foot cells that serve as the tiling scheme. The Escambia County LiDAR Survey was collected under the guidance of a Professional Mapper/Surveyor. The Escambia County, Florida Water Management District uses topographic information to support regulatory, land management and acquisition, planning, engineering, and habitat restoration projects. The Escambia County LiDAR Survey data will support the creation of Federal Emergency Management Agency Flood Insurance Rate Maps (FEMA FIRM) and an integrated ground and surface water model for the Escambia County. All data will be public record as defined by applicable Florida statues. The Escambia LiDAR Survey was collected under the guidance of a Licensed and professional Surveyor and Mapper. The information in this report are the result of the LiDAR surveys performed on the dates indicated and the general conditions at the time. 20060621 Unknown 20060718 Unknown Ground condition Complete None planned -87.643918 -86.835180 31.008016 30.271436 ISO 19115 Topic Category Elevation None Bathymetry/Topography Contour DEM Elevation Height LiDAR Planimetric laser hydrography LAS v 1.0 None Gulf Coast, Florida Pensacola, Florida Escambia County, Florida Florida Escambia United States Manatee Little Manatee McKinnon Gulf Breeze None Users should be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent the actual surface conditions.

Charleston South Carolina 29405 USA 843-740-1200 tcm@csc.noaa.gov Acknowledgement of Dewberry and Davis LLC would be appreciated in products derived from these data. ArcInfo 9.0 Stream shore lines and 2-D coordinate line strings were collected as breaklines using LiDAR that was acquired and processes to FEMA specifications. These breaklines were created from on-screen digitizing using a combination of the LiDAR points and the orthophotography. Attributes were verified using routines that verify the vertical and horizontal positions of the breaklines. The LAS files were flown at a density sufficient to support a maximum final post spacing of 6 feet for unobscured areas. 3001 inc. acquired 110 flightlines between June 21, 2006 and July 18, 2006. The data was divided into 5000' by 5000' foot cells that serve as the tiling scheme. The Escambia County LiDAR Survey was collected under the guidance of a Professional Mapper/Surveyor. The LAS files were flown at a density sufficient to support 2-foot topographic products for unobscured areas. The bare-earth surface will contain voids in areas that were densely vegetated, covered by bridges, buildings, water, fresh asphalt, sand etc. Countywide LiDAR dataset compiled to meet 1 meter horizontal accuracy at 95% confidence level. Countywide LiDAR dataset tested 13.7 cm vertical accuracy at 95% confidence level in open terrain, based on open terrain RMSEz (7 cm) x 1.9600; tested 33.3 cm vertical accuracy at 95% confidence level in all land cover categories combined, based on consolidated RMSEz (17 cm) x 1.9600. Independent accuracy testing was performed by Dewberry & Davis using 101 high accuracy quality control checkpoints distributed throughout the county in five major land cover categories identified by the North West Florida Water Management District. Dewberry used testing procedures consistent with those specified in the National Standard for Spatial Data Accuracy (NSSDA) as well as LiDAR accuracy testing guidelines and specifications published by the Federal Emergency Management Agency (FEMA), National Digital Elevation Program (NDEP), and American Society for Photogrammetry and Remote Sensing (ASPRS).

The ABGPS, inertial measurement unit (IMU), and raw scans are collected during the LiDAR aerial survey. The ABGPS monitors the xyz position of the sensor and the IMU monitors the orientation. During the aerial survey laser pulses reflected from features on the ground surface are detected by the receiver optics and collected by the data logger. GPS locations are based on data collected by receivers on the aircraft and base stations on the ground. The ground base stations are placed no more than 35 km radius from the flight survey area.

The resultant file is in a LAS binary file format. The LAS file version 1.0 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 UTM Zone 16, with units in meters and 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. Point Cloud LiDAR LAS 1.0 format 2006 Filtered Data LiDAR datasets 3001 Inc.

Slidell Louisiana 70458 USA 703-574-2175 8:00-5:00 Filtered and edited data are subjected to rigorous QA/QC according to the 3001 Inc. Quality Control Plan and procedures. Very briefly, a series of quantitative and visual procedures are employed to validate the accuracy and consistency of the filtered and edited data. Ground control is established by 3001, Inc. and GPS-derived ground control points (GCPs) points in various areas of dominant and prescribed land cover. These points are coded according to landcover, surface material and ground control suitability. A suitable number of points are selected for calculation of astatistically significant accuracy assessment as per the requirements of the National Standard for Spatial Data Accuracy. A spatial proximity analysis is used to select edited LiDAR data points within a specified distance of the relevant GCPs. A search radius decision rule is applied with consideration of terrain complexity, cumulative error and adequate sample size. Accuracy validation and evaluation is accomplished using proprietary software to apply relevant statistical routines for calculation of Root Mean Square Error (RMSE) and the National Standard for Spatial Data Accuracy (NSSDA) according to Federal Geographic Data Committee (FGDC) specifications.

The header file for each dataset is complete as define by the LAS 1.0 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 The datasets were delivered in the Districts standard 5000' by 5000' tiling scheme. The tiles are contiguous and do not overlap. The tiles are suitable for seamless topographic data mosaics that include no "no data" areas. The names of the tiles are left padded with zeros as required to achieve a five character length and all files utilize the LAS file extension.

Charleston South Carolina 29405 USA 843-740-1200 tcm@csc.noaa.gov The NOAA National Geophysical Data Center (NGDC) received Lidar data files on external harddrive. The disk contains 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 on this disk 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. 20071226 DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce Pamela Grothe Mailing and Physical Address
