The data were collected January - March 2010. The area of coverage includes the coastline in Baldwin and Mobile Counties in Alabama and the following Florida counties: Bay, Escambia, Franklin, Gulf, Okaloosa, Santa Rosa, and Walton. HawkEye integrates topographic and bathymetric lidar sensors with a digital camera on a single remote sensing platform for use in coastal mapping and charting activities. The topographic lidar sensor has a pulse repetition rate of 64 kHZ at 1064 nm (red wavelength). The bathymetric lidar sensor has a pulse repetition rate of 4 kHz at 532 nm (green wavelength). Native lidar data is not generally in a format accessible to most GIS systems. Specialized in-house and commercial software packages are used to process the native lidar data into 3-D positions that can be imported into GIS software for visualization and further analysis. The data were provided to NOAA CSC in decimal degrees of latitude and longitude, referenced to the NAD83 ellipsoid and in meters. The National Geodetic Survey's (NGS) GEOID03 model was used to transform the vertical positions from ellipsoid to orthometric heights referenced to the North American Vertical Datum of 1988 (NAVD88). The format of the file was LAS version 1.0. For data storage and Digital Coast provisioning purposes, NOAA CSC converted the orthometric heights (NAVD88) back to ellipsoidal heights using GEOID03. These data were collected as a part of the Gulf of Mexico - Alabama and Florida project to depict the elevations above and below the water for the First Return, Last Return, and Hydro in the Alabama and Florida coastal zone.

The vertical accuracy of the data is better than +/- 0.15 m (RMSE) 0.15 Not provided These data were collected using the Hawk Eye system. It is owned by BlomUK and operated through contract. The system collects topographic lidar data at 64 kHz, bathymetric lidar data at 4 kHz and RGB imagery covering the LiDAR area. Aircraft position, velocity and acceleration information are collected through a combination of IRS and GPS system (POS AV 410). All raw data streams are transferred to the office for downloading and processing in Coastal Survey Studio software. Aircraft position data are processed using Applanix software and the results are combined with the lidar data to produce 3-D positions for each lidar shot. Upon inspection and QC/QC in the software packages TerraSolid and Fledermaus, anomalous data are flagged as invalid. Especially designed HawkEye tool then converts all valid data from ellipsoid to orthometric height based on NGS GEOID03 model and exports topographic data as a series of ASCII files with a single file per flightline per 5 km box. The flightline ASCII files are imported into TerraScan <v10> module within Microstation <V8i>. The data are thinned to eliminate duplicate points. A customized classification macro is used to distinguish ground points (2) and unclassified points (1). The classification results are QC'd and any misclassified points are manually edited.

The files contained LiDAR intensity and elevation measurements. CSC performed the following processing on the data for data storage and Digital Coast provisioning purposes: 1. The bathymetric lidar points were converted from ASCII format to las format. 2. All data were converted from NAVD88 heights to ellipsoid heights using GEOID03. 3. The bathymetric lidar data points were classified according to the ASPRS LAS 1.2 classification scheme as 11 (bathymetry). 4. The LAS header fields were sorted by latitude and updated. 201109 NOAA Coastal Services Center mailing and physical

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. 20110922 DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce Pamela Grothe Mailing and Physical Address
