Abstract

Watershed Sciences, Inc. (WS) collected Light Detection and Ranging (LiDAR) data for the United States Forest Service (USFS) in the Elk Creek watershed between July 13-15, 2005. The survey area is located inside the Siuslaw National Forest and encompasses all of Spout Creek (northern extent), Feagles Creek (southern extent), the confluence of these streams with Elk Creek (western extent), and up the headwaters of Elk Creek (eastern extent). The initial study area (~23,454 acres) was buffered by 200 meters, extending the contracted survey area to 26,385 acres.

Laser points were collected over the study area using an Optech ALTM 3100 LiDAR system set to acquire points at an average spacing of >8 points per square meter. The system also recorded individual return intensities (per laser return) that are used to create models that display surface reflectivity. Using this data, a bare-earth digital elevation model (DEM) was created with 1 meter horizontal resolution in UTM 10N projection and NAVD88 orthometric heights using geoid03.

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.

Data Quality

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:

Absolute Accuracy: This is the comparison of laser points to real time kinematic (RTK) ground level survey data. A total of 354 RTK GPS measurements were compared to ground laser points collected for comparison with the LiDAR point data. The deviation RMSE is 0.054 meters and the standard deviation is 0.053 meters, with a median (50th percentile) absolute deviation of 0.036 meters and a 95th percentile of 0.102 meters.

Internal Consistency: Internal consistency refers to the ability to place a laser point in the same location over multiple flight lines, GPS conditions and aircraft attitudes. The data were analyzed for internal consistency between opposing and orthogonal flight lines and passed divergence test requirements of less than 0.15 meters per any one overlapping flight line.

Laser Noise: For any given target, laser noise is the breadth of the data cloud per laser return (i.e., last, first, etc.). Lower intensity surfaces (roads, rooftops, still/calm water) will experience higher laser noise. The laser noise range for this mission varies between 0.040 - 0.070 meters

Lineage Statement:

Watershed Sciences, Inc. (WS) collected Light Detection and Ranging (LiDAR) data for the United States Forest Service (USFS) in the Elk Creek watershed between July 13-15, 2005. NOAA OCM received the data and ingested it into the Digital Coast Data Access Viewer for distribution.

Process Steps

Process Step 1

CC ID: 1293236
Description:

Acquisition.

The Optech 3100 system was set to a 71kHz laser repetition rate and flown at 1,000 meters above ground level (AGL), capturing a 20o scan width (10 o from NADIR). These settings yielded points with an average density of > 8.0 per square meter, with an average spot spacing of 32cm. The entire area was surveyed with opposing flight line overlap of 50% to reduce laser shadowing and increase surface laser painting. The system allows up to four range measurements per pulse, and all were processed for the output datasets. The data stream from the IMU was stored independently during the flight, and was differentially corrected and integrated with LiDAR pulse data during post processing. Throughout the survey, a dual frequency DGPS base station recorded fast static (1 Hz) data. The station was located at the eastern edge of the study area, near Marys Peak, Oregon.

Process Date/Time: 2017-01-01 00:00:00

Process Step 2

CC ID: 1293238
Description:

Two differential GPS units were deployed and used to process kinematic solutions to the onboard GPS and inertial measurement unit (IMU) using PosPAC v4.2. Points were computed per flight line using the REALM Survey Suite v3.5.2. Microstation V8 and TerraScan were used to import the points into bins, remove pits and birds, and compute the bare earth model. TerraModeler was then used to create TINs and output ARCINFO ASCII lattice models, which were then imported into ArcMap to render one-meter mosaics of first returns, vegetation and ground models.

Process Step 2

CC ID: 1293237
Description:

The NOAA Office for Coastal Management (OCM) received DEM files in ESRI GRID format from DOGAMI. The data were in UTM 10N coordinates and NAVD88 (Geoid03) elevations, with all units in meters. OCM converted the files to the open-source cloud-optimized GeoTIFF format (COGs) for provisioning purposes.
