The obtained RMSEr value is multiplied by a conversion factor of 1.7308 to yield the horizontal component of the National Standards for Spatial Data Accuracy (NSSDA) reporting standard where a theoretical point will fall within the obtained radius 95 percent of the time. For most of the AOIs in the OLC Forest Practice project area, the flying altitude was 2500 meters, the IMU error was 0.002 decimal degrees, and the GNSS positional error was 0.023 meters. Based on these parameters, this project was produced to meet 0.896 feet (0.273 meters) horizontal accuracy at the 95% confidence level. The flying altitude was slightly higher during the November 20, 2022, acquisition for the Sweet Home AOI at 2532 meters, while the IMU error and GNSS positional error were the same as above. Based on these parameters, this portion of the project was produced to meet 0.907 feet (0.277 meters) horizontal accuracy at the 95% confidence level. result: (missing) report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Vertical Positional Accuracy evaluationMethodDescription: This data set was produced to meet ASPRS Positional Accuracy Standard for Digital Geospatial Data (2014) for a 10-cm RMSEz Vertical Accuracy Class. The NVA was tested with 128 independent check points located in open terrain and distributed throughout the project as feasible. These check points were not used in the calibration or post processing of the lidar point cloud data. Specifications for this project require that the NVA be 0.196 meters or better AccuracyZ at 95% confidence level. Vegetated Vertical Accuracy (VVA) is also to be computed from the classified las. The VVA was tested with 103 check points in Tall Grass, Forest, and Shrub. These check points were also withheld from the calibration and post processing of the lidar point cloud data and distributed throughout the project area as feasible. Specifications for this project require that the VVA be 0.300 meters or better AccuracyZ at the 95th percentile. The 128 independent NVA check points were surveyed using the closed level loop technique. Elevations interpolated from the classified lidar surface were compared to the elevation values of the surveyed NVA check points. The RMSE was computed to be 0.083 feet (0.025 meters) resulting in an AccuracyZ at the 95% confidence level of 0.162 feet (0.049 meters). NVA AccuracyZ has been tested and meets the required 0.196 meter NVA at 95% confidence level using (RMSEz * 1.9600) for the classified lidar point cloud as defined by the National Standards for Spatial Data Accuracy (NSSDA) and herein reported using National Digital Elevation Program (NDEP)/ASPRS Guidelines. The 103 independent VVA check points were surveyed using the closed level loop technique. Elevations interpolated from the classified lidar surface were compared to the elevation values of the surveyed VVA check points. The RMSE was computed to be 0.306 feet (0.093 meters) resulting in an AccuracyZ at the 95% confidence level of 0.659 feet (0.201 meters). VVA AccuracyZ has been tested and meets the required 0.300 meter VVA at 95% confidence level using (RMSEz * 1.9600) for the classified lidar point cloud as defined by the National Standards for Spatial Data Accuracy (NSSDA) and herein reported using National Digital Elevation Program (NDEP)/ASPRS Guidelines. result: (missing) report: (DQ_CompletenessCommission) nameOfMeasure: Completeness Report evaluationMethodDescription: These LAS data files include all data points collected.

Review flight lines and data to ensure complete coverage of the study area and positional accuracy of the laser points. 2. Resolve kinematic corrections for aircraft position data using kinematic aircraft GPS and static ground GPS data. 3. Develop a smoothed best estimate of trajectory (SBET) file that blends post-processed aircraft position with sensor head position and attitude recorded throughout the survey. 4. Calculate laser point position by associating SBET position to each laser point return time, scan angle, intensity, etc. Create raw laser point cloud data for the entire survey in *.las format. Convert data to orthometric elevations by applying a Geoid 18 correction. 5. Import raw laser points into manageable blocks to perform manual relative accuracy calibration and filter erroneous points. Classify ground points for individual flight lines. 6. Using ground classified points per each flight line, test the relative accuracy. Perform automated line-to-line calibrations for system attitude parameters (pitch, roll, heading), mirror flex (scale) and GPS/IMU drift. Calculate calibrations on ground classified points from paired flight lines and apply results to all points in a flight line. Use every flight line for relative accuracy calibration. 7. Adjust the point cloud by comparing ground classified points to supplemental ground control points. dateTime: DateTime: 2022-11-20T00:00:00 processStep: (LI_ProcessStep) description: Lidar Post-Processing: 1.

The files were in OR Statewide Lambert NAD83(2011) international feet coordinates and the elevations were in NAVD88 (GEOID18) international feet. The LAZ files had these classifications: 1 = unclassified; 2 = ground (or Bare Earth); 7 = low noise; 17 = bridges; 18=high noise; 22 = temporal exclusion. NOAA OCM processed all of the point classes to the Digital Coast Data Access Viewer (DAV). OCM performed the following processing on the data for Digital Coast storage and provisioning purposes: 1. Internal OCM scripts were run to check the number of points by classification and by flight ID and the gps, elevation, and intensity ranges. 2. Internal OCM scripts were run on the LAZ files to: a. Convert from orthometric (NAVD88) elevations to ellipsoid elevations using the GEOID18 model b. Convert from OR Statewide Lambert NAD83(2011) international feet coordinates to geographic coordinates c. Convert from elevations in feet to elevations in meters d. Assign the geokeys, to sort the data by gps time and zip the data to database and to AWS S3. dateTime: DateTime: 2026-04-10T00:00:00 processor: (CI_ResponsibleParty) organisationName: NOAA Office for Coastal Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (843) 740-1202 address: (CI_Address) electronicMailAddress: coastal.info@noaa.gov role: (CI_RoleCode) processor source: (LI_Source) sourceCitation: (CI_Citation) title: LAZ Files date: (missing) citedResponsibleParty: (CI_ResponsibleParty) organisationName: Oregon Dept. of Geology and Mineral Industries (DOGAMI) role: (CI_RoleCode) originator processStep: (LI_ProcessStep) description: The dataset has been mosaiced, reprojected, and clipped as needed from the original input files using PDAL and GDAL commands. dateTime: DateTime: 2026-04-14 processor: (CI_ResponsibleParty) individualName: NOAA Office for Coastal Management contactInfo: (CI_Contact) address: (CI_Address) electronicMailAddress: coastal.info@noaa.gov role: (CI_RoleCode) processor | |
