gov.noaa.csc.maps:2005_PostKatrina_Topobathy_m31 DOC/NOAA/NOS/CSC/CRS > Coastal Remote Sensing Program, Coastal Services Center, National Ocean Service, NOAA, U.S. Department of Commerce 20061016 These data were collected by the Joint Airborne Lidar Bathymetry Technical Center of Expertise using the CHARTS system. The data includes hydrographic and topographic data. The data were collected to depict the post-Hurricane Katrina elevations above and below water along the immediate coastal zone and to provide height information required for processing hyperspectral imagery. 20051012 20051211 Ground Condition Complete As needed -90.371622 -84.934814 30.857725 29.198248 None Lidar Bathymetry Topography None Gulf Coast Biloxi Louisiana Gulf Breeze Destin None November 2005 Post-Hurricane Katrina none These data depict the heights at the time of the survey and are only accurate for that time. Any conclusions drawn from analysis of this information are not the responsibility of NOAA, the Coastal Services Center, or JALBTCX.

Data are not attributed. N/A These data are not attributed. The data provided in this file were tested against ground truth data. At these locations the lidar data matched within 0.20 meters, and different flight line data agreed within 0.20 meters. These data covered the required survey area with minimal gaps in data coverage. The data postings are very consistent with postings at about 1.3m density. The data positions were obtained using post processed KGPS methods. The horizontal accuracy of the data is better than +/- 0.75m. 0.75 1 Sigma The data positions were obtained using post processed KGPS methods. The vertical accuracy of the data is better than +/- 0.20m. 0.20 1 Sigma DOD/USARMY/USACE/JALBTCX > Joint Airborne Lidar Bathymetry Technical Center of Expertise, U. S.

Department of Defense Unpublished material Unknown globe disc 20051111 20051122 Ground Condition 05045 and 05046 This is an xyz dataset collected and provided by CESAM-OP-J, JALBTCX. These data were collected using the CHARTS surveys system. It is owned by the Naval Oceanographic Office and operated through contract. The system collects topographic lidar data at 20kHz and hydrographic data at 3kHz. The system also collects RGB imagery at 1Hz. A CASI-1500 hyperspectral line scanner is integrated with the system as well. Aircraft position, velocity and acceleration information are collected through a combination of Novatel and POS A/V equipment. Raw data are collected and transferred to the office for downloading and processing in SHOALS GCS software. GPS data are processed using POSPac software and the results are combined with the lidar data to produce 3-D positions for each lidar shot. These data are edited using Fledermaus software where anomalous data are removed from the dataset. The edited data are unloaded from SHOALS GCS, converted from ellipsoid to orthometric heights, based on the GEOID03 model, and split into greographic tiles covering approximately 5km each. 20060210 The NOAA Coastal Services Center (CSC) received files in ascii format. The files contained lidar intensity and elevation measurements. CSC performed the following processing on the data to make it available within the Lidar Data Retrieval Tool (LDART): 1. Each hydro/topo last return ascii file was converted to las files. Default values for which there is no corresponding input were assigned as follows for each las elevation data record: intensity = 0, retn = 1, nret = 1, class = 0 2. The las files were sorted by latitude and the las header fields were updated. 20060421 Coastal Remote Sensing Program TCM Project Scientist mailing and physical address

Charleston South Carolina 29405 United States (843) 740-1200 csc@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. 20060103 DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce Pamela Grothe Mailing and Physical Address
