The U.S. Army Corps of Engineers collects and maintains LiDAR data including orthophotos in coastal areas of the United States and its territories. The Corps acquires this data in the course of performing its mission of flood control, navigation, environmental engineering, and support for the Army and others. This is not a bare earth data set. These data were collected as a part of the National Coastal Mapping Program to depict the elevations above and below the water for the New York coastal zone. Incomplete coverage in files 01_H, 02_H, 04_H, 05_H of the bathymetric data is due to high water turbidity. 20070604 20070730 Ground condition Complete As needed -79.065808 -76.099208 43.964200 43.213900 ISO 19115 Topic Category Elevation None Bathymetry/Topography Lidar Elevation None US New York Great Lakes Lake Ontario None NCMP U.S. Army Corps of Engineers, Mobile District CHARTS SHOALS JALBTCX None June, July 2007 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be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions.

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. None provided 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 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 data are broken into files, with each covering approximately 5km along the shoreline. The box layout index is provided by the shape file, "ny_ontario_boxes", and the box numbers for labels are in the "Box" field of the shape file. An example of the file name is "2007_NCMP_NY_Ontario_03_TL_IGLD85.xyz." The last two digits within the file name corresponds with the same box names used to divide the NCMP data collected. The data were collected and processed in geographic coordinates and ellipsoid heights. The positions are relative to NAD83 in decimal degrees of longitude and latitude. The data were then converted to IGLD85 using the VDatum program from NOAA (National Oceanic and Atmospheric Administration). 2008 JALBTCX Data Production Manager mailing and physical address

The files contained Lidar elevation and intensity measurements. Both the topo and hydro points were classed as 'never classified.' The data were provided in Geographic coordinates and ellipsoidal heights and in IGLD85 heights. CSC performed the following processing to the ellipsoidal height data to make it available within the Digital Coast: 1. LASEdit was used to convert the ascii formatted files to las format. 2. Both the topo and the hydro points were classified as 'never classified.' Hydro points were changed to class 11, 'water' and topo points were changed to 'unclassified.' 3. The LAS data were sorted by latitude and the headers were updated. 20090223 Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Coastal Services Center (CSC) Coastal Elevation Mapping (CEM) Project Scientist Mailing and physical address

Charleston SC 29405-2413 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. 20110328 DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce Pamela Grothe Mailing and Physical Address
