Data Quality
Vertical Positional Accuracy: |
Watershed Sciences analysis of vertical accuracy (in the data report) states that 122 reserved ground survey points were collected for independent verification, resulting in a fundamental vertical accuracy (FVA) of 0.050 meters or an RMSE of 0.025 meters. DOGAMI conducted an independent accuracy assessment with 199 GCPs and reported "The data delivered to DOGAMI was found to have a mean vertical offset of -0.118 meters (-0.389 feet) and an RMSE value of 0.0034 meters (0.0111 feet). Offset values ranged from -0.190 meters (-0.624 feet) to 0.048 meters (0.157 feet)." This cannot be correct as the mean offset cannot be greater than the RMSE. Based on the histogram of differences provided, the RMSE is likely 0.12 meters. |

Process Steps
Process Step 1
Description: |
Acquisition. LiDAR data acquisition was conducted from June 06 to June 20, 2016. The survey utilized a Leica ALS 80 laser system mounted in a Cessna 208. Scan angles near nadir were used to increase penetration of vegetation to ground surfaces. Ground level GPS and aircraft IMU were collected during the flight. |

Process Date/Time: | 2016-05-28 00:00:00 |
Process Step 2
Description: |
Processing. 1. TRAJECTORY: Aircraft trajectory (position and attitude) were calculated based on on-board GPS and IMU data with post-processing refinement through coincident static GPS collection. 2. POST-PROCESSING: Laser point return coordinates (x,y,z) were computed using sensor-specific post processing software, combining LiDAR return range and intensity information with aircraft trajectory information. 3. INITIAL QAQC: The post-processed LiDAR files were assembled into flight lines and reviewed for gaps and consistency, as well as systematic noise. 4. CALIBRATION: Custom algorithms evaluated individual swaths for misalignments based on IMU configuration as well as aircraft attitude variability. Offsets were resolved through surface and linear matching algorithms that minimize variability in elevation and slope. Descriptive statistics, thresholds, and specifications providing transparency for data calibration are discussed in the accompanying Data Report. 5. GROUND MODELING: Ground classified point cloud was generated through proprietary data processing tools, with settings and thresholds appropriate to landscape and vegetation condition. 6. ARTIFACT FILTRATION: Noise and processing artifacts were filtered using post-processing software and proprietary quality control methods. 7. ACCURACY ASSESSMENT: Vertical accuracy for the LiDAR dataset was assessed against Ground Check Points (GCP) distributed throughout the study area. See the accompanying Data Report for methodology, descriptive statistics, and relevant standards and reporting language. |

Process Step 3
Description: |
NOAA/OCM received the data from DOGAMI in Arc Grid format . Data were in NAD83(2011) Oregon Lambert horizontally and NAVD88 (Geoid12a) vertically. All units were international feet. For ingest into the Digital Coast Data Access Viewer the data was converted to NAD83(2011) geographic coordinates and the vertical datum was changed to NAD83(2011) ellipsoid heights in meters using GEOID12a. |
