LiDAR data was processed to achieve a bare ground surface. LiDAR data was delivered in LAS format. Final product delivery of bare ground surface was intended to suit the needs of NOAA for elevation-related tasks. 20060112 20060228 Ground Condition Complete As needed -87.32 -86.77 31.01 30.30 None Elevation LiDAR Light Detection and Ranging Beach Topography Digital Elevation Model DEM Geographic Names Information System Florida Santa Rosa County None Any conclusions drawn from analysis of this information are not the responsibility of Photo Science, Inc, NOAA, or the Coastal Services Center.

LiDAR data at the interface between the land and ocean was collected (when possible) during periods when tides were predicted to be below mean lower low water. 3. LiDAR data accuracy is in accordance with the National Standard for Spatial Data Accuracy (NSSDA). When compared to GPS survey grade points in generally flat non-vegetated areas, at least 95% of the positions have an error less than or equal to 36.3 cm (equivalent to root mean square error of 18.5 cm if errors were normally distributed). LiDAR data was delivered covering the full extent of Santa Rosa County, Florida, with coverage extending 1000m beyond the county boundary.

Utilizing Photo Science's ALS-50 LiDAR sensor, data was collected to cover Santa Rosa County (including a 1000m buffer around the county). Data was collected in a total of 243 flightlines (including re-flights and cross sections) at a pulse rate of 44,000 points per second. 20060112 Raw LiDAR data (collected as Process Step 1) was processed to create a bare ground surface. Process included calibration of LiDAR data to remove systematic errors (utilizing Leica's ALS Processor software), adjustment of elevation data to control positions (utilizing TerraScan software for control comparisons and adjustments), and both automatic and manual editing to correctly classify ground and non-ground data (utilizing TerraScan and TerraModeler softwares). In addition, QC steps were performed before and after processing. QC steps included line-to-line vertical comparisons and coverage checks, and were performed with TerraScan and GeoCue softwares. 20060601 The NOAA Coastal Services Center (CSC) received files in LAS 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. The las files were converted from UTM coordinates to Geographic coordinates. 2. The las header fields were sorted by latitude and updated. 20061102 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
