The LiDAR DEM was delivered as first return, last return, bare earth, and water delivery in LAS format. Contract Number: W91278-04-D-0001/0003 EN. Project Number: C-05-054. Contractor: R&M Consultants, Inc., Anchorage, AK. Subcontractor: Woolpert, Inc., Dayton, OH. The data was initially used to support the U.S. Army Corps of Engineers mission in Debris Removal following Hurricane Katrina, 3D Modeling and Flood Study Analysis. 20050919 20051009 ground condition Complete As needed -89.688056 -87.992500 30.787778 30.14361 ASPRS LiDAR None elevation laser topography digital elevation model DEM erosion U.S. Department of Commerce, 1995, Countries, Dependencies, Areas of Special Sovereignty, and Their Principal Administrative Divisions (Federal Information Processing Standard (FIPS) 10-4): Washington, D.C., National Institute of Standards and Technology US U.S. Department of Commerce, 1987, Codes for the Indentification of the States, the District of Columbia and the outlying areas of the United States, and associated areas (Federal Information Processing Standards (FIPS) 5-2): Washington, D.C., National Institute of Standards and Technology.

Charleston South Carolina 29405 United States (843) 740-1200 csc@csc.noaa.gov Features detected in LiDAR points are consistent with features on LiDAR intensity images. Data was checked to make sure a full coverage of project area at data acquisition phase. One flight line was reflown. The points have better than one meter post spacing with overlap removed. Horizontal accuracy is better than 0.45 meters according to system specification and calibration. No field check on horizontal accuracy has been performed. Vertical accuracy of 15 centimeters (NSSDA RMSEZ) in flat and open areas (i.e. low grass, plowed fields, lawn, golf courses). 0.06 86 survey control points and NGS based on RMSE points spreading all over the project area have been used as QC points to check LiDAR vertical accuracy.

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. The las files were sorted by latitude and the las header fields were updated. 20050105 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
