* » Abstract |
Lidar data in the Colville and Idaho Panhandle National Forests covering 1,888 square miles. Collected in 2016 for the U.S. Forest Service. |
* Purpose |
The primary purpose of the lidar survey was to establish measurements of the bare earth surface, as well as top surface feature data for providing geometric inputs for modeling, other numerical modeling and economic related assessments. |

Accuracy | |
Analytical Accuracy | |
Horizontal Positional Accuracy |
The horizontal errors in lidar data are largely a function of GNSS positional error, INS angular error, and flying altitude. Therefore, lidar data collected with GNSS error of 8cm and the IMU error of 0.00427 degrees at an altitude of 1,965m; the expected radial horizontal positional error will be RMSEr = 28.5cm. |
Vertical Positional Accuracy |
The fundamental vertical accuracy (95% confidence for bare earth) was 0.130 meters based upon 255 GPS points. |

» Description |
Differential GPS unit in aircraft collected positions at 2 Hz. Airborne GPS data was processed using the Inertial Explorer (version 8.60.5025) software. Flights were flown with a minimum of 6 satellites in view (10° above the horizon) and with a PDOP of â¤4 when the laser was online. For all flights, the GPS data can be classified as good, with GPS residuals of 3cm average or better but none larger than 10cm being recorded. Data collected by the lidar unit is reviewed for completeness, acceptable density and to make sure all data is captured without errors or corrupted values. In addition, all GPS, aircraft trajectory, mission information, and ground control files are reviewed and logged into a database. |

» Description |
Atlantic used a combination of Waypoint and Leica software products to extract the lidar swath data from the raw flight records. Waypoint Inertial Explorer is used to extract the raw IPAS ABGPS/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 SBETâs are combined with the raw laser scan files to export the (*.las) formatted swath point clouds. |

» Description |
The calibrated point cloud data from the laser sensor was merged to produce processed (*.las) file(s) including but not limited to 3D position, intensity, and time-stamp. A filtering methodology was utilized to produce a multi-return surface elevation model dataset with bare-earth conditions. GeoCue, TerraScan, and TerraModeler software was used for the initial batch processing and manual editing of the (*.las) point clouds. Outlined in Table 4 are the classification codes utilized for this project. |

» Description |
Data were received from the U.S. Forest Service in LAZ format, USFS region 6 Albers projection horizontally and NAVD88 (Geoid12b) vertically. All units were meters. NOAA OCM converted the data to geographic coordinates on the NAD83(2011) ellipsoid for ingest into the Digital Coast Data Access Viewer. The data were also put into the Cloud Optimized Point Cloud version of the LAZ format. |
