The data are broken into boxes. The box layout index is provided by the shape file, "in_boxes.shp", and the box numbers for labels are in the "Box" field of the shape file. The data file names are based on the year, project, area name, box number, and product type. An example of the file name is "2008_NCMP_IN_Michigan_07_02DS08070_006_080916_1955_A_00452.las." The 14th digit within the file name corresponds with the box names used. The data was collected and processed in geographic coordinates and ellipsoid heights. The positions are relative to NAD83 in decimal degrees of longitude and latitude. The heights were converted from ellipsoid to orthometric heights using the Geoid03 model with the results in meters. The date and time of each point are also MM:SS.SSSSSS. The format of the file is LAS version 1.0 These data were collected as a part of the NCMP to depict the elevations ABOVE AND BELOW the water for the First Return OR Last Return OR Hydro in the Illinois coastal zone.

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. Not Provided The data positions were obtained using post processed KGPS methods. The horizontal accuracy of the data is better than +/- 0.75 meters. 0.75 1 Sigma The data positions were obtained using post processed KGPS methods. The vertical accuracy of the data is better than +/- 0.20 meters. 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 edited data are written to 5 km tiles along the shoreline using chartsLAS, a program written by NAVO. This program reads data from the original binary format files and produces separate ASCII files for first and last return data. The data are converted from ellipsoid to orthometric heights, based on the GEOID03 model, within the chartsLAS program. 2009 JALBTCX Data Production Manager mailing and physical

The files contained LiDAR intensity and elevation measurements. CSC performed the following processing on the data for data storage and Digital Coast provisioning: 1. The data were converted from ASCII to las format. 2. The data were classified as 1 for the topo data (no bare earth) using the topo last (TL) elevation and 11 for the hydro data. 3. The data were converted from NAVD88 heights to ellipsoid heights using Geoid03. 4. The LAS header fields were sorted by latitude and updated. 201105 NOAA Coastal Services Center Clearinghouse Manager mailing and physical

Charleston SC 29405 US 843-740-1210 clearinghouse@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. 20110630 DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce Pamela Grothe Mailing and Physical Address
