gov.noaa.csc.maps:2006_GL_Topobathy_m40 Joint Airborne LiDAR Bathymetry Technical Center of Expertise (JALBTCX) 20070322 Final Charleston, SC NOAA's Ocean Service, Coastal Services Center (CSC) http://csc-s-maps-q.csc.noaa.gov/dataviewer/viewer.html 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. These data were collected along the Indiana, Michigan, Ohio and Pennsylvania coasts of the Great Lakes using the CHARTS (Compact Hydrographic Airborne Rapid Total Survey) system and industry based coastal mapping and charting systems. The purpose of this survey was to collect topographic and hydrographic elevations to obtain the existing conditions of the beach and near shore in support of the Joint Airborne LiDAR Bathymetric Technical Center of Expertise National Coastal Mapping Program. However, depths were not attained in many areas due to water clarity. 20060614 20060926 Ground condition Complete As needed -087.20 -079.98 44.08 41.37 ISO 19115 Topic Category Elevation None LiDAR Bathymetry/Topography DEM None US Great Lakes Indiana Burns Harbor Michigan St. Clair River Lake St. Clair Ohio Pennsylvania Lake Huron Lake Michigan Lake Erie None June 2006 September 2006 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be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions.

Acquisition - Data were acquired using a SHOALS-1000T. Sensor orientation was measured using a POS AV 410, while images were acquired at 1Hz using a Duncantech DT4000 digital camera. Prior to survey PDOP was checked and missions planned to avoid PDOP greater than 3.5. During survey the plane was always within 30km of a GPS ground control point, to provide a good quality position solution. Final positions were determined using a post-processed inertially aided Kinematic GPS (KGPS) solution. GPS ground control data were acquired at 1Hz. Data received by the airborne system were continually monitored for data quality during acquisition operations. Display windows showed coverage and information about the system status. In addition, center waveforms at 5Hz were shown. All of this information allowed the airborne operator to assess the quality of data being 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 heights were converted from ellipsoid to geoid heights (NAVD88) using the Geoid03 model with the results in meters. Data were processed in the field to verify coverage and data quality.

Kiln MS 399556 US 228-252-1103 Processing - Data were processed using the SHOALS Ground Control System (GCS). The GCS includes links to Applanix POSPac software for GPS and inertial processing, and IVS Fledermaus software for data visualization, 3D editing and tie-line analysis. Data were processed in NAD83 horizontal and vertical datum. Data were later converted to the NAVD88 vertical datum using the GEOID03 model. The date and time of each point are also MM:SS.SSSSSS. Fugro in-house utilities were used to extract XYZ data from the native LiDAR files and split the data in to pre-defined boxes, each covering approximately 5km of shoreline. ASCII files include: Longitude, Latitude, Elevation, Date, Time, and Intensity. Unknown JALBTCX Mailing and physical address

Charleston SC 29405 US 843-740-1200 tcm@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. 20071226 DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce Pamela Grothe Mailing and Physical Address
