LiDAR data for the project and the validation site was collected by a single aerial vendor on ESP team between February 10, 2017 and April 10, 2017 using Geiger-mode Avalanche Photodiode (GmAPD) sensors. The aerial vendor on the ESP team was Harris Corporation (Harris).Three GmAPD (Geiger-mode) sensors (serial numbers 001,002 and 003) were used for the data collection of LiDAR data at a 0.35 meter nominal post spacing (NPS). The following counties were collected in the February through April, 2017 collection: Ashe, Avery, Buncombe, Burke, Caldwell, Cherokee, Clay, Graham, Haywood, Henderson, Jackson, Macon, Madison, McDowell, Mitchell, Polk, Rutherford, Swain, Transylvania, Watauga and Yancey. All data was collected during leaf-off conditions. Ground survey support for the project included the establishment of GPS base stations and the collection of control points used for calibration. All LiDAR and derivative products for this project met the specifications stipulated in Delivery Order 35, the NC LiDAR Standard, and the USGS minimum standards for QL1 LiDAR data. This project was a joint effort between NC Emergency Management, NC Geodetic Survey, and the NCDOT. The following people served as the main representatives for each stakeholder: NC Emergency Management- Hope Morgan (primary contact) and John Dorman; NC Geodetic Survey- Gary Thompson and Watson Ross; NCDOT- Keith Johnston and Marc Swartz, and the United States Geological Survey (USGS). This metadata supports the data entry in the NOAA Digital Coast Data Access Viewer (DAV). For this data set, the DAV is leveraging the Entwine Point Tiles hosted on AWS. The purpose of this project was to update existing LiDAR data, originally collected between 2000 and 2005, with more accurate and clearly defined LiDAR data utilizing the latest in sensor technology. Although created for the North Carolina Floodplain Mapping Program 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 community. The North Carolina Floodplain Mapping Program was established in response to the extensive damage caused by Hurricane Floyd in 1999.

The North Carolina Geodetic Survey performed a vertical quality control (QC) survey in Phases 4 and 5 of the statewide LiDAR elevation project. The purpose of the survey was to test the elevation points contained in a dataset that was obtained by utilizing airborne Light Detection And Ranging (LiDAR) technology. The QC test points were collected utilizing the North Carolina Real Time Network (NCRTN), and with conventional survey methods in areas unsuitable for GNSS observations. Please refer to the Vertical Accuracy report for further information. A link to this report is provided in the URL section of this metadata record. NVA = 0.262 ft (8 cm) RMSEz VVA = 0.380 ft (11.6 cm) RMSEz Completeness Report These LAS data files include all data points collected. No points have been removed or excluded. A visual qualitative assessment was performed to ensure data completeness. No void areas or missing data exist. The point cloud is of good quality and data passes Non-Vegetated Vertical Accuracy specifications. Conceptual Consistency ESP Associates tested the classified LAS files for both vertical and horizontal accuracy. All data covers the project area, tile to tile with no gaps or no data areas exceeding specifications The NOAA Office for Coastal Management (OCM) ingested references to the USGS Entwine Point Tiles (EPT) hosted on Amazon Web Services (AWS) into the Digital Coast Data Access Viewer (DAV). The DAV accesses the point cloud as it resides on AWS under the usgs-lidar-public-container. LAS Point Classification: The point classification is performed as described below. The bare earth surface is then manually reviewed and edited using TIN visualization and profiles to ensure correct classification on the Class 2 (Ground) points as well as the other classifications required by NCEM. After the bare-earth surface is finalized, it is then used to generate all hydro-breaklines through heads-up digitization in a 3D environment for all rivers equal to or larger than 100 feet in width and all closed water bodies equal to or greater than 2 acres. Island equal or greater than 1 acre are mapped are included. All ground (Class 2) lidar data inside of the Lake Pond and Double Line Drain hydro flattening breaklines were classified to water (Class 9) using ESP Utilities. A buffer of 1 foot was also used around each hydro-flattened feature to classify ground (Class 2) points within the buffer to breakline proximity (Class 10). All Lake Pond Island and Double Line Drain Island features were reviewed in ESP Analyst and checked to ensure that the ground (Class 2) points were reclassified to the correct classification after the automated classification was completed. Overlap data was not processed as Geiger mode LiDAR is flown at a 55 percent overlap with a Palmer scanner. Road polygons derived from heads-up digitization from aerial imagery and the LiDAR were derived for only state-maintained roads per the latest available road database from the North Carolina Department of Transportation. These polygons were then used to classify all ground points with the road edges to roads (Class 13). All remaining classifications required by NCEM such as buildings (Class 6) and vegetation strata (Classes 3, 4, and 5) were derived using automated filters in Terrascan then checked for gross errors and review to ensure that a 98 percent confidence level in classification was met. All data was manually reviewed and any remaining artifacts in the ground (Class 2) removed using functionality provided by ESP Analyst. ESP Analyst was used as a final check of the bare earth dataset. ESP Utilities was then used to create the deliverable industry-standard LAS files for both the All Point Cloud Data. ESP Utilities was used to verify full LAS header and projection information. All data was delivered in the North Carolina State Plane Coordinate System, with a horizontal datum of NAD83 (2011), vertical datum of NAVD88 (Geoid 12B), in US Survey Feet. Data was delivered tiled to a 2,500 foot by 2,500 foot tiling scheme unless otherwise specified in this product description. All LiDAR was delivered in LASer (LAS) version 1.4 standard format. Products for this project derived from the source LiDAR included: intensity images in GeoTIFF format, hydro-flattening breaklines in ESRI File Geodatabase format, Digital Elevation Models (DEMs) in TIF format, ESRI Terrain Datasets (by county) in ESRI File Geodatabase format, product and project-level metadata, and project reports to include the Report of Survey, Post-Acquisition Report, and Project Report. 2017-01-01T00:00:00 Original point clouds in LAS/LAZ format were restructured as Entwine Point Tiles and stored on Amazon Web Services. The data were re-projected horizontally to WGS84 web mercator (EPSG 3857) and no changes were made to the vertical (NAVD88 GEOID12B meters). U.S. Geological Survey processor References to the entwine point tiles and data reports were ingested into the Digital Coast Data Access Viewer. No changes to the data were made at this point. The Data Access Viewer will access the point cloud as it resides on AWS under the usgs-lidar-public container. 2022-01-07T00:00:00 Office for Coastal Management processor Entwine Point Tiles on AWS USGS https://usgs.entwine.io/ WWW:LINK-1.0-http--link USGS Entwine point clouds Source Citation URL information publisher LAS point cloud on AWS USGS publisher
