The data includes hydrographic and topographic data. These data were collected as a part of the National Coastal Mapping Program to depict the elevations above and below water along the east coastal zone . 20051211 20060205 Ground Condition Complete As needed -81.50 -78.50 33.95 25.70 None Lidar Bathymetry Topography None South Carolina Georgia Florida None December 2005 January 2006 February 2006 None These data depict the heights at the time of the survey and are only accurate for that time.

Charleston South Carolina 29405 United States (843) 740-1200 csc@csc.noaa.gov Acknowledgement of the Joint Airborne Lidar Bathymetry Center of Expertise (JALBTCX) would be appreciated in any publications or derived products. Lidar data between different flight lines matched 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 +/- 3.0m. 3.0 2 Sigma The data positions were obtained using post processed KGPS methods. The vertical accuracy of the data is better than +/- 0.30m. 0.30 2 Sigma JALBTCX(comp.) Unpublished material Unknown globe disc 20051211 20060205 Ground Condition Lidar surface This is an xyz dataset collected and provided by CESAM-OP-J, JALBTCX. These data were collected using a SHOALS-1000T system. It is owned and operated by Fugro Pelagos performing contract survey services for the US Army Corps of Engineers. The system collects topographic lidar data at 10kHz and hydrographic data at 1kHz. The system also collects RGB imagery at 1Hz. 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. 20060424 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. 20060715 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. This data is currently being served via LDART at http://www.csc.noaa.gov/ldart . This data can be used to re-populate the system. The data are provided on this disk in two forms, ascii x,y,z data and also 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 is NAD 83, however some is 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 Kelly Stroker Mailing and Physical Address
