The following areas were requested to be covered: Fremont-Winema National Forest (FRE-WINNF) in Lakeview, Oregon; Malheur National Forest (MALNF) in John Day, Oregon; Willamette National Forest (WILNF) in Bend, Oregon; Okanogan-Wenatchee National Forest (OKA-WENNF) in Wenatchee, Washington; and Rogue River-Siskiyou National Forest (RR-SNF) in Medford, Oregon. Table 1 below details the Areas of Interest (AOIs) requested for 2020 reflight. Aerial LiDAR data for this task order was planned, acquired, processed and produced at an aggregate nominal pulse spacing (ANPS) of 0.35 meters and in compliance with USGS National Geospatial Program LiDAR Base Specification version 1.3.

The term NVA refers to assessments in clear, open areas (which typically produce only single lidar returns); the term VVA refers to assessments in vegetated areas (typically characterized by multiple return lidar). The Vertical Accuracy Assessment utilized the required parameters for Vertical Data Accuracy Class IV. Completeness Report Area of interest covers project area. A visual qualitative assessment was performed to ensure data completeness. No void areas or missing data exist. The raw point cloud is of good quality and data passes NVA specifications. Void areas (i.e., areas outside the project boundary but within the tiling scheme) are coded using a unique NODATA value. This value is identified in the appropriate location within the file header. Conceptual Consistency All lidar data and lidar derived data covers the entire area of interest. All lidar point cloud tiles show no edge artifacts or mismatches from tile to tile. Void areas (i.e. areas outside the project boundary but within the tiling scheme) are coded using a unique NODATA value. This value is identified in the appropriate location within the file header. Data cover the entire area specified for this project. Aircraft and Sensor Information and Flight Plan Execution Atlantic operated a PACDV (N750DV) outfitted with an Optech Galaxy Prime LiDAR system during the collection of the project area. Atlantic acquired 1588 passes of the AOI as a series of perpendicular and/or adjacent flight-lines executed in 44 flight missions conducted between June 29, 2018 and January 24, 2019. Onboard differential Global Navigation Satellite System (GNSS) unit(s) recorded sample aircraft positions at 2 hertz (Hz) or more frequency. LiDAR data was only acquired when a minimum of six (6) satellites were in view. 2020-09-20T00:00:00 Ground Control Survey A total of 198 ground survey points were collected in support of this project. Point cloud data accuracy was tested against a Triangulated Irregular Network (TIN) constructed from LiDAR points in clear and open areas. A clear and open area can be characterized with respect to topographic and ground cover variation such that a minimum of five (5) times than 1/3 of the RMSEZ deviation from a low-slope plane. Slopes that exceed ten (10) percent were avoided. Each land cover type representing ten (10) percent or more of the total project area were tested and reported with a GCP. In land cover categories other than dense urban areas, the tested points did not have obstructions forty-five (45) degrees above the horizon to ensure a satisfactory TIN surface. The GCP value is provided as a target. It is understood that in areas of dense vegetation, swamps, or extremely difficult terrain, this value may be exceeded. The GCP value is a requirement that must be met, regardless of any allowed 'busts' in the VVA(s) for individual land cover types within the project. Checkpoints for the assessment are required to be well-distributed throughout the land cover type, for the entire project area 2018-09-19T00:00:00 LiDAR Point Cloud Generation Atlantic used Leica software products to download the IPAS ABGNSS/IMU data and raw laser scan files from the airborne system. Waypoint Inertial Explorer is used to extract the raw IPAS ABGNSS/IMU data, which is further processed in combination with controlled base stations to provide the final Smoothed Best Estimate Trajectory (SBET) for each mission. The SBETs are combined with the raw laser scan files to export the LiDAR ASCII Standard (*.las) formatted swath point clouds. 2021-04-12T00:00:00 LiDAR Calibration Using a combination of GeoCue, TerraScan and TerraMatch; overlapping swath point clouds are corrected for any orientation or linear deviations to obtain the best fit swath-to-swath calibration. Relative calibration was evaluated using advanced plane-matching analysis and parameter corrections derived. This process was repeated interactively until residual errors between overlapping swaths, across all project missions, was reduced to no more than 2cm. A final analysis of the calibrated lidar is preformed using a TerraMatch tie line report for an overall statistical model of the project area. Upon completion of the data calibration, a complete set of elevation difference intensity rasters (dZ Orthos) are produced. A user-defined color ramp is applied depicting the offsets between overlapping swaths based on project specifications. The dZ orthos provide an opportunity to review the data calibration in a qualitative manner. Atlantic assigns green to all offset values that fall below the required RMSDz requirement of the project. A yellow color is assigned for offsets that fall between the RMSDz value and 1.5x of that value. Finally, red values are assigned to all values that fall beyond 1.5x of the RMSDz requirements of the project 2021-04-12T00:00:00 LiDAR Classification Multiple automated filtering routines are applied to the calibrated LiDAR point cloud identifying and extracting bare-earth and above ground features. GeoCue, TerraScan, and TerraModeler software was used for the initial batch processing, visual inspection and any manual editing of the LiDAR point clouds. Classified point clouds were cut to match the tile index and its corresponding tile names and delivered in .laz format. 2021-04-12T00:00:00 Digital Coast Processing Data were received from the USFS Region 6 in LAZ format with a projection of NAD83(2011) USFS Region 6 Albers meters and vertically in NAVD88 meters using Geoid12b. Data were in LAS 1.4 format (the data report has conflicting information regarding the LAS version). For ingestion in the Data Access Viewer, data were reverted to NAD83(2011) geographic coordinates and ellipsoid heights (EPSG:6319). The time of collection listed in process step 1 is noted to be incorrect, but was left as the original metadata record from Atlantic, Inc. Based upon the time stamps in the lidar records, the collection appears to be from July 29, 2020 to August 20, 2020. This suggests that some of the process steps were copied from a different metadata records and may not reliably describe the collection and processing of this dataset. Due to the possibility that parts of the metadata were copied from earlier projects, there may be some question regarding the correct GEOID model. The metadata received states Geoid12b. At the time of the project, the current NGS Geoid was Geoid18. 2021-04-12T00:00:00 NOAA Office for Coastal Management (843) 740-1202 coastal.info@noaa.gov processor Classified lidar data USFS originator The dataset has been mosaiced, reprojected, and clipped as needed from the original input files using PDAL and GDAL commands. 2026-06-30NOAA Office for Coastal Managementcoastal.info@noaa.govprocessor
