Product: Classified LAS 1.4 files, formatted to 215 individual 3000ft x 3000ft tiles covering the McKenzie River Corridor Topobathymetric Lidar project area.
Geographic Extent: This dataset and derived products encompass an area covering approximately 8,216 Acres of McKenzie River.
Dataset Description: The McKenzie River Corridor Topobathymetric Lidar project called for the planning, acquisition, and processing of Topobathymetric Lidar data collected to Quality Level 1 (QL1) standards. Project specifications are based on the Geological Survey National Geospatial Program Lidar Base Specification, 2020 Revision A. The data was developed based on the NAD83 2011 horizontal datum and the NAVD88 Geoid 18 vertical datum. Data was projected in Oregon Statewide Lambert Conformal Conic. Lidar data was delivered as calibrated and classified LAS 1.4 files. Non-Vegetated Vertical Accuracy (NVA) was assessed using 23 check points located on bare earth in clear, unobstructed areas. Submerged Topography accuracy was assessed using 174 check points collected as feasible in depths up to 1m. Vegetated Vertical Accuracy (VVA) was assessed using 12 check points in Shrub, Forest, Tall Grass landcover types. Single swath nominal pulse spacing (NPS) was designed to be 0.35 at nadir. Aggregate Nominal Pulse Spacing (ANPS) was calculated to be 0.17 using all valid first return points. Derived products include: Topbathymetric Digital Elevation Models (DEMs), Topobathymetric Bare Earth Digital Elevation Models (DEMs), Highest Hit Digital Surface Models (DSMs), 2D waters edge breaklines, and a bathymetric coverage shape.
Ground Condition: Ground condition was free of snow and acquisition occurred free of smoke, fog and cloud cover.
The NOAA Office for Coastal Management (OCM) downloaded 215 laz files from this USGS site and processed the data to the Data Access Viewer (DAV): https://rockyweb.usgs.gov/vdelivery/Datasets/Staged/Elevation/LPC/Projects/OR_McKenzieRiverCorridor_Topobathy_2021_D21/OR_MKRC_Topobathy_2021/LAZ/

Abstract: |
Product: Classified LAS 1.4 files, formatted to 215 individual 3000ft x 3000ft tiles covering the McKenzie River Corridor Topobathymetric Lidar project area. Geographic Extent: This dataset and derived products encompass an area covering approximately 8,216 Acres of McKenzie River. Dataset Description: The McKenzie River Corridor Topobathymetric Lidar project called for the planning, acquisition, and processing of Topobathymetric Lidar data collected to Quality Level 1 (QL1) standards. Project specifications are based on the Geological Survey National Geospatial Program Lidar Base Specification, 2020 Revision A. The data was developed based on the NAD83 2011 horizontal datum and the NAVD88 Geoid 18 vertical datum. Data was projected in Oregon Statewide Lambert Conformal Conic. Lidar data was delivered as calibrated and classified LAS 1.4 files. Non-Vegetated Vertical Accuracy (NVA) was assessed using 23 check points located on bare earth in clear, unobstructed areas. Submerged Topography accuracy was assessed using 174 check points collected as feasible in depths up to 1m. Vegetated Vertical Accuracy (VVA) was assessed using 12 check points in Shrub, Forest, Tall Grass landcover types. Single swath nominal pulse spacing (NPS) was designed to be 0.35 at nadir.

Purpose: |
The purpose of the lidar data was to produce a high accuracy 3D dataset that meets all necessary standards laid out by the 3D Elevation Program and the McKenzie River Corridor Topobathymetric Lidar contract. The lidar point cloud data were used to create classified lidar LAS files, Topobathymetric DEMs, topobathymetric DEMs, highest hit DSMs, 2D breaklines delineating water features within the study area, and a bathymetric coverage shape. |

Description: |
Entwine Point Tile (EPT) is a simple and flexible octree-based storage format for point cloud data. The data is organized in such a way that the data can be reasonably streamed over the internet, pulling only the points you need. EPT files can be queried to return a subset of the points that give you a representation of the area. As you zoom further in, you are requesting higher and higher densities. A dataset in EPT will contain a lot of files, however, the ept.json file describes all the rest. The EPT file can be used in Potree and QGIS to view the point cloud. |

Data Quality
Horizontal Positional Accuracy: |
Horizontal Accuracy = 4 cm RMSEr |
---|---|
Vertical Positional Accuracy: |
This data was produced to meet ASPRS Positional Accuracy Standards for Digital Geospatial Data (2014) for a 10-cm RMSEz Vertical Accuracy Class. USGS Determined Vertical Accuracy Non-Vegetated Vertical Accuracy (NVA) = 3.6 cm RMSE Vegetated Vertical Accuracy (VVA) = 19.35 cm at the 95th Percentile |
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. Bathymetric void areas have been interpolated. A bathymetric coverage shape has been provided as a separate deliverable. The raw point cloud is of good quality and data passes Non-Vegetated Vertical Accuracy specifications. |
Conceptual Consistency: |
Classified LAS files were tested by NV5 for vertical accuracy. All data is seamless from one tile to the next, no gaps or no data areas. |

Process Steps
Process Step 1
Description: |
Lidar Pre-Processing: 1. 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. Apply refraction correct to bathymetric returns by flightline. 6. Import raw laser points into manageable blocks to perform manual relative accuracy calibration and filter erroneous points. Classify ground points for individual flight lines. 7. 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. 8. Adjust the point cloud by comparing ground classified points to supplemental ground control points. |

Process Step 2
Description: |
Lidar Post-Processing: 1. Classify data to ground and other client designated classifications using proprietary classification algorithms. 2. Manually QC data classification 3. After completion of classification and final QC approval, calculate final NVA, VVA, and density information for the project using ground control quality check points. |

Process Step 3
Description: |
The NOAA Office for Coastal Management (OCM) downloaded 215 laz files from this USGS Rocky ftp site: https://rockyweb.usgs.gov/vdelivery/Datasets/Staged/Elevation/LPC/Projects/OR_McKenzieRiverCorridor_Topobathy_2021_D21/OR_MKRC_Topobathy_2021/LAZ/. The data were in Oregon Lambert, NAD83(2011) Int feet coordinates with vertical elevation in NAVD88 (Geoid18) feet. Data were converted to geographic coordinates, from vertical feet to meters, to ellipsoid heights (using Geoid18), and elevations less than 0 were filtered out, for ingest into the NOAA Digital Coast Data Access Viewer. The observed classes processed to the Data Access Viewer are: 1 = unclassified, 2 = ground, 7 = low noise, 9 = water, 17 = bridge deck, 18 = high noise, 40 = bathy bottom, 41 = water surface, 45 = water column. |
