Abstract

Watershed Sciences, Inc. (WSI) collected airborne Thermal Infrared (TIR) imagery and Light Detection and Ranging (LiDAR) data for the Department of Geology and Mineral Industries (DOGAMI) in Malheur, Harney, and Lake Counties during March and April 2012. This is the final delivery encompassing the four remaining study areas of the DOGAMI TIR and LiDAR survey. The requested acreage for Christmas Valley (13,041 acres), Oregon Military (9,701 acres), Paulina Marsh (56,287 acres), and Baker Pass (44,846 acres) study areas were expanded to include a 100m buffer to ensure complete coverage around survey area boundaries. This expansion results in a total of 13,809 acres, 10,344 acres, 57,768 acres, and 46,194 acres of delivered TIR and LiDAR data, respectively (Figure 1). The TIR imagery provides an accurate data set for detecting and identifying surface expression of geothermal activity. LiDAR data was co-acquired with the TIR imagery and provides highly detailed topographic data for recognizing landforms associated with detected thermal features.

Data Quality

Vertical Positional Accuracy:

The LiDAR quality assurance process uses the data from the real-time kinematic (RTK) ground survey conducted in the AOI. A total of 397, 403, 440, and 459 RTK GPS measurements were collected for the Christmas Valley, OR Military, Paulina Marsh, and Baker Pass AOI’s respectively (Figures 18 – 21). All measurements were collected on hard surfaces and distributed among multiple flight swaths. To assess absolute accuracy the location coordinates of these known RTK ground points were compared to those calculated for the closest ground-classified laser points.

RMSEz for each area:

Christmas Valley = 0.03 meters

OR Military = 0.04 meters

Paulina Marsh = 0.03 meters

Baker Pass = 0.02 meters

Process Steps

Process Step 1

CC ID: 1142780
Description:

Acquisition.

The LiDAR survey utilized a Leica ALS60 sensor mounted in a Cessna Caravan.The Leica system was set to acquire 88,000 laser pulses per second (i.e., 88 kHz pulse rate) and was flown at 1,100 meters above ground level (AGL), capturing a scan angle of ±15o from nadir. With these flight parameters, the laser swath width was 598m and the laser pulse footprint was 26cm. These settings were developed to yield points with an average native pulse density of 4 pulses per square meter over terrestrial surfaces.

All areas were surveyed with an opposing flight line side-lap of ≥50% (≥100% overlap) to reduce laser shadowing and increase surface laser painting. The Leica laser systems allow up to four range measurements (returns) per pulse, and all discernible laser returns were processed for the output dataset.

To accurately solve for laser point position (geographic coordinates x, y, z), the positional coordinates of the airborne sensor and the attitude of the aircraft were recorded continuously throughout the LiDAR data collection mission. Aircraft position was measured twice per second (2 Hz) by an onboard differential GPS unit. Aircraft attitude was measured 200 times per second (200 Hz) as pitch, roll and yaw (heading) from an onboard inertial measurement unit (IMU). To allow for post-processing correction and calibration, aircraft/sensor position and attitude data are indexed by GPS time.

Process Step 2

CC ID: 1142781
Description:

Processing.

1. Resolved kinematic corrections for aircraft position data using kinematic aircraft GPS and static ground GPS data.

Software: Waypoint GPS v.8.10, Trimble Business Center 2.6

2. Developed a smoothed best estimate of trajectory (SBET) file that blends post-processed aircraft position with attitude data. Sensor head position and attitude were calculated throughout the survey. The SBET data were used extensively for laser point and thermal image processing.

Software: IPAS TC v.3.1

3. Calculated laser point position by associating SBET position to each laser point return time, scan angle, intensity, etc. Created raw laser point cloud data for the entire survey in *.las (ASPRS v. 1.2) format. Data were then converted to orthometric elevations (NAVD88) by applying a Geoid03 correction.

Software: ALS Post Processing Software v.2.74

4. Imported raw laser points into manageable blocks (less than 500 MB) to perform manual relative accuracy calibration and filter for pits/birds. Ground points were then classified for individual flight lines (to be used for relative accuracy testing and calibration).

Software: TerraScan v.12.004

5. Using ground classified points per each flight line, the relative accuracy was tested. Automated line-to-line calibrations were then performed for system attitude parameters (pitch, roll, heading), mirror flex (scale) and GPS/IMU drift. Calibrations were performed on ground classified points from paired flight lines. Every flight line was used for relative accuracy calibration.

Software: TerraMatch v.12.001

6. Position and attitude data were imported. Resulting data were classified as ground and non-ground points. Statistical absolute accuracy was assessed via direct comparisons of ground classified points.

Software: TerraScan v.12.004, TerraModeler v.12.002

Process Step 3

CC ID: 1142782
Description:

The NOAA Office for Coastal Management (OCM) received the point cloud LAS files from DOGAMI. The files contained Lidar elevation and intensity measurements. The data were in NAD83(CORS96) UTM 10 or 11 meters coordinates and NAVD88 (Geoid03) vertical meters. OCM transformed the data to geographic coordinates and ellipsoid heights for ingest in the Digital Coast Data Access Viewer.

This metadata record was generated from the project report as no metadata record was received from DOGAMI.
