The OLC's Four Rivers study area encompasses 470,160 acres; Delivery Area One encompasses 80,071 acres, and Delivery Area Two encompasses 390,089 acres. 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. LiDAR data collection began on September 10, 2014 and was completed on June 16, 2015. Delivery Area One LiDAR was acquired between September 9, 2014 and October 10, 2014. Delivery Area Two was acquired between October 10, 2014 and October 28, 2014, and the following year between March 17, 2015 and June 16, 2015. Settings for LiDAR data capture produced an average resolution of at least eight pulses per square meter. Orthophoto acquisition occurred between August 28, 2014 and September 4, 2014. Final products created include LiDAR point cloud data, three-foot digital elevation models of bare earth ground model and highest-hit returns, 1.5 foot intensity rasters, 6-inch orthophotos, ground density 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.

For the Four Rivers Delivery Area Two study area, 4,763 GSPs were collected; a total of 5,452 GSPs were collected for the entire Four River study area. 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: 0.02 meters, Test that produced the value: Compiled to meet root mean square error. Completeness Report Lidar data has been collected and processed for all areas within the project study area. Conceptual Consistency 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 utilized a Leica ALS80 sensor mounted in a Cessna Grand Caravan aircraft. The systems were programmed to emit single pulses at a rate of 369 kilohertz and flown at 1500 meters above ground level (AGL), capturing a scan angle of +/-15 degrees from nadir (field of view equal to 30 degrees). These settings are 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 65 percent with at least 100 percent 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 accurate description of aircraft position and attitude. Aircraft position is described as x, y, and z and measured twice per second (two hertz) by an onboard differential GPS unit. Aircraft attitude is measured 200 times per second (200 hertz) as pitch, roll, and yaw (heading) from an onboard inertial measurement unit (IMU). 2014-01-01T00:00:00 The NOAA Office for Coastal Management (OCM) received the files in the proprietary ESRI grid format.
