Resource Abstract:
This airborne LiDAR terrain mapping data was acquired January through March 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 Neuse, Pasquotank, Tar-Pamlico, and White Oak River Basins in central and eastern North Carolina. This area consists of 33 counties which are listed below in the Place Keywords field. The data were received by the NOAA Office for Coastal Management from the U.S. Geological Survey (USGS) Center for Lidar Coordination and Knowledge (CLICK). For data storage and Digital Coast provisioning purposes, the OCM 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.

AbsoluteExternalPositionalAccuracy
name Of Measure Vertical Positional Accuracy Report
evaluation Method Description  LIDAR full return mass points were compared with surveyed elevations provided by independent contractors to the NCGS. A vertical bias was acquired after airport calibration based on this comparison. 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. The RMSE value for each county is available in the Lidar Accuracy Assessment Report.

Completeness Commission
evaluation Method Description  The full return mass points contain voids where insufficient energy was reflected from the surface to generate a valid return from the terrain. Voids in the full return mass points tend to occur in water bodies. Wet sand and certain types of vegetation can also cause voids or anomalous elevations.
Completeness Omission

QuantitativeAttributeAccuracy
name Of Measure Quantitative Attribute Accuracy Assessment
measure Description  Less than or equal to 20 cm RMSE of bare earth LIDAR points compared with independent checkpoints.
evaluation Method Description  LIDAR full returns were compared with NCGS QA/QC checkpoints using only single and final returns per pulse. A vertical bias was acquired after airport calibration based on this comparison. 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.
