Lidar intensity data was also collected. CHARTS integrates topographic and bathymetric lidar sensors, a digital camera and a hyperspectral scanner on a single remote sensing platform for use in coastal mapping and charting activities. Data coverage generally extends along the coastline from the waterline inland 500 meters (topography) and offshore 1,000 meters or to laser extinction (bathymetry). The topographic lidar sensor has a pulse repetition rate of 9 kHz at 1064 nm (near-infrared wavelength). The bathymetric lidar sensor has a pulse repetition rate of 1 kHz at 532 nm (green wavelength). Native lidar data is not generally in a format accessible to most Geographical Information Systems (GIS). Specialized in-house and commercial software packages are used to process the native lidar data into 3-dimensional positions that can be imported into GIS software for visualization and further analysis. Horizontal positions, provided in decimal degrees of latitude and longitude, are referenced to the North American Datum of 1983 (NAD83). Vertical positions are referenced to the NAD83 ellipsoid and provided in meters. These data were collected as a part of the National Coastal Mapping Program to depict the elevations above the water for the First Return, Last Return, or Hydro in the Michigan coastal zone. 20080728 20080916 ground condition Complete As needed -86.838156 -85.915215 44.989667 41.748285 ISO 19115 Topic Category elevation None Bathymetry/Topography U.S. Army Corps of Engineers, Mobile District JALBTCX CHARTS SHOALS LiDAR Elevation ASCII XYZ Intensity None United States Michigan Allegan County Benzie County Berrien County Lake Michigan Leelanau County Manistee County Mason County Muskegon County Oceana County Ottawa County Van Buren County None 2008 July August September 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be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions.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. Not 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 system. It is owned by the Naval Oceanographic Office and operated through contract. The system collects topographic lidar data at 9kHz, bathymetric lidar data at 1kHz and 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 410 equipment. All raw data streams are transferred to the office for downloading and processing in SHOALS GCS software. Aircraft position data are processed using POSPac software and the results are combined with the lidar data to produce 3-D positions for each lidar shot. Upon inspection and QA/QC in the software packages Fledermaus and PFM_ABE, anomalous data are flagged as invalid. PFM_ABE's chartsLAS module then converts all valid data from ellipsoid to orthometric heights based on the NGS' GEOID03 model and exports data as a series of first return topography (TF), last return topography (TL) and bathymetry (H) ASCII files. The bathymetry files contain all of the returns from the bathymetric sensor which include returns both above and below the water. 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 3-D position data were sub-divided into a series of ASCII file products, with each covering approximately 5 kilometers of shoreline. The file index was provided by the shape file, "mi_michigan_boxes.shp", and the numbers used to identify files are in the "Box" field of the shape file. The data file naming convention is based on the year, project, area name, "Box" number and product type (topographic or bathymetric). An example file name is "2008_NCMP_MI_Michigan_07_ASCII", where 2008 is the year of data collection, NCMP is the project under which data were collected, MI_Michigan is the area of data collection, 07 is the "Box" number and ASCII is the product type. The ASCII columns are Longitude, Latitude, UTM Zone, Easting, Northing, Elevation (orthometric), Elevation (ellipsoid), Date, Time, and Intensity. 2009 JALBTCX Data Production Manager mailing and physical

The files contained LiDAR elevation and intensity measurements. The points were classed as 'never classified.' The data were provided in Geographic coordinates and ellipsoidal heights and in orthometric 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. The hydro points classification was changed from 'never classified' to class 11, 'bathymetry'. The topo points classification remains as class 0, 'never classified'. 3. The LAS data were sorted by latitude and the headers were updated. 200911 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

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. 20110503 DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce Pamela Grothe Mailing and Physical Address
