Title: 2004 Klamath Basin Rangeland Trust Lidar DEM : Wood River, OR
Status: Completed
Publication Date: 2019-08-29
Abstract:

The Klamath Basin Rangeland Trust contracted with a vendor, Watershed Sciences, Inc (WSI) to collect high resolution topographic data for a portion of the Klamath watershed. The 2004 Wood River project area was collected on September 26th & 27th, 2004. The survey area encompassed the Wood River floodplain from Agency Lake at the southern edge to Annie Creek in the north. The data were collected using an Optech ALTM 3100 LiDAR system set to acquire points at average spacing of 8 points per square meter for parallel overlapping areas. The total area of delivered data equals 62,195 acres. A bare-earth digital elevation model (DEM) was created from this lidar data using ground classified points.

NOAA OCM received the data from Oregon Department of Geology & Mineral Industries (DOGAMI) / The Oregon Lidar Consortium (OLC).

In addition to the bare-earth digital elevation model (DEM), processed lidar point data also received by NOAA's OCM and is available through the Related Items section, below.

Purpose:

This dataset provides high resolution terrain elevation and land cover elevation data in the Wood River Study Area.

Data Quality

Vertical Positional Accuracy:

RMSe = 0.07 meters. This is a vendor-reported vertical accuracy calculated with 263 independent ground survey points. See project report for more details.

Completeness Report:

Data set was found to be complete. See the Acceptance Report for more detailed information.

The study area was buffered by 100 meters to ensure complete coverage. While there may be the appearance of data gaps (outside on the known survey gaps), these are limited to areas under buildings or over very still/calm water surface (ponds, pools, etc.) where the bare ground model required greater than 10 meters to build a triangle. In these cases, the models recorded no data. The GRID data are an average value that fits triangles within a specified area (1 m2). By setting distance limits to triangle length, longer interpolations are avoided for areas with low point density where laser pulses are obstructed or absorbed. It is more typical for commercial LiDAR providers to deliver data sets that allow long triangle lengths to prevent any gaps in the resulting GRID data sets. However, such interpolation of the data may provide a false sense that data are continuous throughout the study area, when in fact, they are not. In the final processing we tend to limit triangle to explicitly demonstrate absence of laser return length and thus allow data gaps where data densities are insufficient to adequately characterize surfaces. This method also effectively displays laser return gaps

Process Steps

Process Step 1

CC ID: 1154534
Description:

Acquisition.

The Optech 3100 system was set to a 100kHz laser repetition rate and flown at 1,000 meters AGL, capturing a 36o scan width (18 o from NADIR). These settings yielded an average spacing of 8 points per square meter. The entire area was surveyed with opposing flight line overlap, to reduce laser shadowing and increase surface laser painting. A section was flown with both opposing flight line overlap and orthogonal flight line overlap. While the system allows up to four range measurements per pulse, only the first and last returns were processed in the output. The data stream from the IMU was stored independently during the flight, differentially corrected and integrated with LiDAR pulse data during post processing. Throughout the survey two dual frequency DGPS Trimble 5700 base stations recorded fast static (1 Hz) data.

Process Step 2

CC ID: 1154535
Description:

Processing.

Laser point return coordinates were computed using the REALM software suite based on independent data from the LiDAR system (pulse time, scan angle), IMU (aircraft attitude), and aircraft position (differentially corrected and optimized using the multiple DGPS base stations data) (Optech, 2003a). The inertial measurement data were used to calculate the kinematic corrections for the aircraft trajectories using PosPAC v4.1 (Applanix, 2003a and 2003b). Flight lines and LiDAR data were reviewed to insure complete coverage of the study area and positional accuracy of the laser points.
