* » Abstract |
No metadata record for this data set was provided to the NOAA Office for Coastal Management (OCM). This record was created with information from the data report. A link to the data report is provided in the URL section of this metadata record. LiDAR data acquisition occurred between July and October 2016. The Atlantic Group, LLC (Atlantic) successfully completed lidar acquisition for the Fremont-Winema, Willamette, Deschutes, and Umpqua National Forests areas of interest (AOI). This metadata record describes the Timber Butte project area in the Willamette National Forest, which is a subset of the larger collection. The lidar for the larger AOI was acquired in fifty (50) flight missions completed on October 25th, 2016. The total project area encompasses 1,275,059 acres, 5,160 square kilometers or 1,992 square miles. |
* 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. |

Analytical Accuracy | |
Horizontal Positional Accuracy |
As described in Section 7.5 of the ASPRS Positional Accuracy Standards for Digital Geospatial Data, 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 |
A total of three hundred and five (305) control points were collected for 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 5 times the NPS exists with less than 1/3 of the RMSEZ deviation from a low-slope plane. Slopes that exceed 10 percent were avoided. Below are the vertical accuracy reporting requirements for this project: Vertical Accuracy Reporting Requirements in Meters: RMSEZ ≤ 10.0cm (Bare-Earth) FVA ≤ 19.6cm 95% Confidence Level (Bare-Earth) Vertical Accuracy Reporting Requirements in Feet: RMSEZ ≤ 0.328ft (Bare-Earth) FVA ≤ 0.643ft 95% Confidence Level (Bare-Earth) *The terms FVA (Fundamental Vertical Accuracy), SVA (Supplemental Vertical Accuracy) and CVA (Consolidated Vertical Accuracy) are from the National Digital Elevation Program (NDEP) Guidelines for Digital Elevation Data (2004). The term FVA refers to open terrain, urban and levee classes; the term SVA refers to classes tested that are in addition or supplemental to the open terrain; the term CVA refers to the consolidated accuracy of the data from all classes (FVA + SVA). FVA is 0.132 m or 6.7 cm RMSE CVA is 0.072 m |

» Description |
The NOAA Office for Coastal Management (OCM) received 259 lidar point cloud files in laz format from DOGAMI. The files contained lidar elevation and intensity measurements. The data were in Albers NAD83 Forest Service Region 6, meters, coordinates and NAVD88 (Geoid12B) elevations in meters. The data were classified as: 1-Unclassified, 2-Ground, 7 - Low Noise, 18 - High Noise. OCM processed all classifications of points to the Digital Coast Data Access Viewer (DAV). Classes available on the DAV are: 1, 2, 7, 18. OCM performed the following processing on the data for Digital Coast storage and provisioning purposes: 1. An internal OCM script was run to check the number of points by classification and by flight ID and the gps and intensity ranges. 2. Internal OCM scripts were run on the laz files to convert from orthometric (NAVD88) elevations to ellipsoid elevations using the Geoid 12B model, to convert from Albers NAD83 Forest Service Region 6 coordinates in meters, to geographic coordinates, to assign the geokeys, to sort the data by gps time, and zip the data to database and to http. |
