Centralina Council of Governments (CCOG) Cabarrus County IT Department 20060626 Contours10ft2005 vector digital data Frederick, MD 21704 EarthData International, Inc Contours10ft2005 withheld This metadata document describes the processing of filtered LiDAR data from the existing North Carolina Floodplain Mapping LiDAR Bare Earth date. The main objective of this project was to provide a filtered county wide data set that can more easily be ingested and displayed on available computers. The bounding coordinates provided within the Spatial Domain section represent a rectangle covering the total area in which the project is located. The actual project area follows the boundary of Cabarrus County, NC. The LiDAR was flown at an altitude of 10,000 feet above mean terrain (AMT). Swath width of terrain covered in a single flightline was approximated 3,173 meters. Field of View for the Leica GeoSystems Aeroscan system used was 55 degrees. en 20060626 Publication Date Complete Unknown -80.815566 -80.237762 35.557090 35.137820 1459989.999892 1629999.999922 510000.000091 659999.999975 None LiDAR Elevation Filtered Bare Earth Last Return None North Carolina NC Cabarrus County None Although care has been taken in preparing the information contained in this data, Cabarrus County does not guarantee the accuracy thereof.

Box 707 Concord, NC 28026-0707 Filtered Bare Earth LiDAR data set was produced by EarthData International, Inc under contract to Centralina Council of Governments (CCOG). ESRI ArcCatalog 9.3.1.4000 Feature Class The filtered bare earth data set was produced from the existing North Carolina Floodplain Mapping LiDAR Bare Earth data set. 25cm RMSE (cm) of bare earth LiDAR points compared with independent checkpoints Data was filtered using automated procedures followed by a manual review of the completed data set. The bare earth surface will contain voids where insufficient energy was reflected from the surface to generate a valid return from the terrain. LiDAR Bare Earth data returns were compared with surveyed elevations provided by independent contractors to the NCGS. The 5% of points with largest error were removed (outliners). 2 meters RMSE (m) of bare earth LiDAR points compared with independent checkpoints EarthData International, Inc 20060626 Filtered Bare Earth LiDAR from theNorth Carolina Floodplain Mapping Program model Frederick, MD EarthData International, Inc. raster digital data 20060321 Publication Date LiDAR The LiDAR used in this process was flown at an altitude of 10,000 feet above mean terrain (AMT).

Source Data - LiDAR Elevation Model - Existing Bare Earth North Carolina Floodplain Mapping LiDAR Data set A step-by-step breakdown of the production process follows - 1. The existing bare earth digital surface model was imported into the TerraScan software package used to filter the LiDAR data. 2. The LiDAR data was classified using the model keypoints tool in TerraScan. 2.a. Parameters were selected based on four tiles representative of the entire job. 2.a. Final parameters are then applied to entire project with spot checks being performed on different terrain types and adjusted if necessary. 5. The data was inspected for completeness and quality. 6. The final data set was output to .xyz format and prepared for delivery. 20060626 EarthData International, Inc mailing and physical address
