        abstract:  This airborne LiDAR terrain mapping data was acquired in the spring of 2001. The data were collected for the floodplain mapping program for the state of North Carolina. The data were collected for the state in three phases: 1, 2, and 3. This metadata record describes that data that were in phase 1 of collection and fall within the Cape Fear and Lumber River Basins in central and eastern North Carolina. This area consists of 30 counties which are listed below in the Place Keywords field. The data were received by the NOAA Coastal Services Center from the U.S. Geological Survey (USGS) Center for Lidar Coordination and Knowledge (CLICK). For data storage and Digital Coast provisioning purposes, the CSC converted the data to geographic coordinates and ellipsoid (Geoid99) elevations. The data are unclassified.
        purpose:  These data were collected and derived by the North Carolina Floodplain Mapping Program (www.ncfloodmaps.com) as part of its effort to modernize FEMA Flood Insurance Rate Maps (FIRM) statewide. Although created for specific use in the engineering aspects of floodplain delineation, the data were also developed to address the elevation data requirements of the broader geospatial data user community. The North Carolina Floodplain Mapping Program was established in response to the extensive damage caused by Hurricane Floyd in 1999.
        credit:  Acknowledgement of the North Carolina Floodplain Mapping Program is appreciated when using the data set. This data set was developed for the North Carolina Floodplain Mapping Program by Greenhorne and O'Mara, Inc. Additional data development support was provided by 3Di Technologies, Inc. as subcontractor to Greenhorne and O'Mara and by Airborne1 Corp. and Sanborn Colorado, LLC as sub-tier suppliers to 3Di.

            nameOfMeasure:  Horizontal Positional Accuracy
            measureDescription:  Horizontal Accuracy is derived from the total error budget of the LIDAR Sensor and the Post Processed GPS Kinematic solution. Error budgets and calibration values have been established that include GPS error of the aircraft location in space during flight, the angular error of the Inertial Measurement Unit resulting in error budget for aircraft platform attitude in pitch, roll and yaw, and the angular error in the LIDAR scan mirror position for each laser shot. These and other minor error budgets are used to derive the maximum horizontal position error of the LIDAR footprint on the terrain surface. Performance against this budget is checked with laboratory measurements and flight calibrations to assure conformance to specification. Further information on calibration reports can be obtained in these reports, available at: http://portal.ncdenr.org/web/lr/geodetic/floodplaininfo.

            measureDescription:  Internally collected QAQC points and qualified NGS Benchmarks were compared to interpolated TIN values for the LIDAR data sets. The difference was calculated as the QAQC value minus the LIDAR interpolated TIN value. The differences were then squared and summed. The resulting value was divided by the number of points compared to determine the mean. The square root of the mean was calculated to arrive at the Root Mean Square Error (RMSE) of the elevation differences, or RMSE(z). Acceptable values for RMSE would be 20cm or less for designated coastal counties and 25cm for inland counties. The county reports which have the county RMSE value are available at: http://portal.ncdenr.org/web/lr/geodetic/floodplaininfo.

            measureDescription:  State QAQC points measured by the NCGS were compared to interpolated TIN values for the LIDAR data sets. The difference was calculated as the QAQC value minus the LIDAR interpolated TIN value. The differences were then squared and summed. The resulting value was divided by the number of points compared to determine the mean. The square root of the mean was calculated to arrive at the Root Mean Square Error (RMSE) of the elevation differences, or RMSE(z). Additional information on accuracy is contained in the county reports, which may be viewed at: http://portal.ncdenr.org/web/lr/geodetic/floodplaininfo.
            evaluationMethodDescription:  LIDAR Bare Earth data were compared with NCGS QA/QC checkpoints. The 5% of points with the largest error were removed (outliers). For the NC Floodplain Mapping Program, the vertical accuracy for coastal counties is less than or equal to 20 cm RMSE. For mainland counties, the vertical accuracy of the elevation data is less than or equal to 25 cm RMSE. More information about the

                description:  Production Narrative: Data collected were processed to determine that valid GPS values were achieved on all flights. The flight data was processed using proprietary automated algorithms that calculate the x, y, and z value of each point by combining GPS position of the aircraft, IMU attitude of the aircraft, range of the laser pulse, and scan angle of the laser scanner. Resulting data from each flight line was then compared to crossing and bordering flight lines to identify any residual pitch, roll or yaw errors. Data were also compared to calibration flights over airports in or adjacent to the Cape Fear and Lumber River Basins. Data were then edited in TerraModel by comparing contour lines, shaded relief models (hillshading) and points clouds within tiles and from one tile to the next. Finally, the data were compared to available ground survey data prior to submitting to the State for QAQC checks.

Points received in a file format other than LAS were converted to LAS, if the data contained adequate attribute information to create a valid LAS file and without the loss of any original attribute information. The points have been re-tiled into a standard Quarter-Quad, or Quarter-Quarter-Quad, scheme for publication on the CLICK website. The data remain in the Coordinate Reference System in which they were received. No alteration of any sort, of either the geometry or attribute values or structure has been performed.

The files contained lidar elevation and intensity measurements. The data were unclassified, in State Plane coordinates, and were vertically referenced to NAVD88. CSC performed the following processing for data storage and Digital Coast provisioning purposes: 1. The data were converted from State Plane coordinates to geographic coordinates. 2. The data were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid99. 3. The data were sorted by time. 4. The data were converted to LAZ format.

                description:  The NOAA National Geophysical Data Center (NGDC) received lidar data files via ftp transfer from the NOAA Coastal Services Center. The data are currently being served via NOAA CSC Digital Coast at http://www.csc.noaa.gov/digitalcoast/. The data can be used to re-populate the system. The data are archived in LAS or LAZ format. The LAS format is an industry standard for LiDAR data developed by the American Society of Photogrammetry and Remote Sensing (ASPRS); LAZ is a loseless compressed version of LAS developed by Martin Isenburg (http://www.laszip.org/). The data are exclusively in geographic coordinates (either NAD83 or ITRF94). The data are referenced vertically to the ellipsoid (either GRS80 or ITRF94), allowing for the ability to apply the most up to date geoid model when transforming to orthometric heights.
