WSI has collected Light Detection and Ranging (LiDAR) data of the Oregon Tillamook-Yamhill Study Area for the Oregon Department of Geology and Mineral Industries (DOGAMI). The Oregon LiDAR Consortium's Tillamook- Yamhill project area encompasses approximately 200,000 acres in Tillamook and Yamhill County in northwestern Oregon. The area was flown between September 23rd and October 5th, 2012,The collection of high resolution geographic data is part of an ongoing pursuit to amass a library of information accessible to government agencies as well as the general public.
The LiDAR survey utilized Leica ALS50 and ALS60 sensors mounted in either Cessna Caravan 208B or Partenavia P.68 aircrafts. Depending on the pairing of sensor and aircraft, the systems were programmed to emit laser pulses at a rate between 96-105 kHz, and flown at 900 meters above ground level (AGL), capturing a scan angle of +-30 degrees from nadir. These settings are developed to yield points with an average native density of greater than eight points per square meter over terrestrial surfaces.
Final products created include LiDAR point cloud data, 1 meter digital elevation models of bare earth ground model and highest-hit returns, intensity rasters, study area vector shapes, and corresponding statistical data. Final deliverables were projected in Oregon Statewide Lambert Conformal Conic. This metadata was created for the bare earth digital elevation models.

Vertical accuracy statistical analysis uses ground survey points in open areas where the LiDAR system has a "very high probability" that the sensor will measure the ground surface and is evaluated at the 95th percentile. For the Tillamook-Yamill study area, 3,636 RTK points were collected. No independent survey data were collected, thus statistics are "Compiled to Meet".
For more information about the vertical accuracy, please refer to the final report, listed above in the Supplemental_Information field
of this metadata record.
; Quantitative Value: 0.04 meters, Test that produced the value: Compiled to meet root mean square error.
Lidar data has been collected and processed for all areas within the project study area.
Upon receipt from vendor (WSI), all LiDAR data was independently reviewed by staff from the Oregon Department of Geology and Mineral Industries (DOGAMI) to ensure project specifications were met. All data were inventoried for completeness and data were checked for quality, which included examining LiDAR data for errors associated with internal data consistency, model quality, and accuracy.

The LiDAR survey occurred between September 23rd and
October 5th, 2012, utilizing Leica ALS60 and ALS50 sensors mounted in either a Cessna Caravan 208B or a Partenavia P.68 aircraft. The systems were programmed to emit single pulses at around 100 kHz and flown at 900 m AGL, capturing a scan angle of 30 degrees from nadir. These settings were developed to yield points with an average native density of greater than eight pulses per square meter over terrestrial surfaces.
The study area was surveyed with opposing flight line side-lap of greater than 60% with at least 100% overlap to reduce laser shadowing and increase surface laser painting. The system allows up to four range measurements per pulse, and all discernible laser returns were processed for the output dataset.
To solve for laser point position, it is vital to have an ac- The LiDAR survey utilized Leica ALS50 and ALS60 sensors mounted in either Cessna Caravan 208B or Partenavia P.68 aircrafts.

Aircraft position is described as x, y and z and measured twice per second (2 Hz) by an onboard differential GPS unit. Aircraft attitude is measured 200 times per second (200 Hz) as pitch, roll and yaw (heading) from an onboard inertial measurement unit (IMU).
