These files contain topographic and bathymetric lidar data collected by the HawkEye system along the coast of Alabama and the gulf coast
of Florida. 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 OCM 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 OCM converted the orthometric heights (NAVD88) back to ellipsoidal heights using GEOID03.
In addition to these lidar point data, the bare earth Digital Elevation Models (DEM) created from the lidar point data are also available. These data are available for custom download at the link provided in the URL section of this metadata record.

Abstract: |
These files contain topographic and bathymetric lidar data collected by the HawkEye system along the coast of Alabama and the gulf coast of Florida. 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 OCM 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 OCM converted the orthometric heights (NAVD88) back to ellipsoidal heights using GEOID03.

Process Steps
Process Step 1
Description: |
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. |

Process Step 2
Description: |
The NOAA Office for Coastal Management (OCM) received unclassified bathymetric files in ASCII format and classified (ASPRS classifications of 1 (unclassified) and 2 (ground)) topographic files in las format. The files contained LiDAR intensity and elevation measurements. OCM 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. |
