Quantum Spatial has collected Light Detection and Ranging (LiDAR) data for the Oregon LiDAR Consortium (OLC) Okanogan FEMA study area. This study area is located in northern Washington.
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. In June 2015 QSI employed remote-sensing lasers in order to obtain a total area flown of 263,839 acres. Settings for LiDAR data capture produced an average resolution of at least eight pulses per square meter.
Final products created include RGB extracted (from NAIP imagery) LiDAR point cloud data, one-meter digital elevation models of highest hit and bare earth ground models, one-meter density rasters, one-half-meter intensity rasters, study area vector shapes, and corresponding statistical data. Final deliverables are projected in UTM Zone 11. Lidar point clouds were projected back to geographic coordinates with ellipsoid heights for storage in the Digital Coast Data Access Viewer. Custom processing may have further changed the projection and datums. See the spatial reference information and processing steps for details.

Horizontal Positional Accuracy
unknown
Vertical Positional Accuracy
Vertical Accuracy reporting is designed to meet guidelines presented in the National Standard for Spatial Data Accuracy (NSSDA) (FGDC, 1998) and the ASPRS Guidelines for Vertical Accuracy Reporting for LiDAR Data V1.0 (ASPRS, 2004). The statistical model compares known ground survey points (GSPs) to the closest laser point. 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 reports the fundamental vertical accuracy value (FVA=1.96*RMSE).
For the OLC Okanogan FEMA study area, a total of 2,673 GSPs were collected. An additional 197 reserved ground survey points were collected for independent verification, resulting in a fundamental vertical accuracy (FVA) of 0.083 meters.
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: 0.083 meters, Test that produced the value: Tested to meet FVA at a 95 percent confidence level in meters.
Completeness Report
LiDAR data has been collected and processed for all areas within the project study area.
Conceptual Consistency
Upon receipt from vendor (Quantum Spatial), 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 June 19, 2015 and July 10, 2015, utilizing a Leica ALS70 mounted in a Cessna Grand Caravan and a Cessna Mini Caravan. The systems were programmed to emit single pulses at around 198 kHz and flown at 1,400 m AGL, capturing a scan angle of 15 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.
To solve for laser point position, an accurate description of aircraft position and attitude is vital. Aircraft position is described as x, y, and z and was measured twice per second (two hertz) by an onboard differential GPS unit. Aircraft attitude is described as pitch, roll, and yaw (heading) and was measured 200 times per second (200 hertz) from an onboard inertial measurement unit (IMU).
The LiDAR sensor operators constantly monitored the data collection settings during acquisition of the data, including pulse rate, power setting, scan rate, gain, field of view, and pulse mode. For each flight, the crew performed airborne calibration maneuvers designed to improve the calibration results during the data processing stage. They were also in constant communication with the ground crew to ensure proper ground GPS coverage for data quality. The LiDAR coverage was completed with no data gaps or voids, barring non-reflective surfaces (e.g., open water, wet asphalt). All necessary measures were taken to acquire data under good conditions (e.g., minimum cloud decks) and in a manner (e.g., adherence to flight plans) that prevented the possibility of data gaps. All QSI LiDAR systems are calibrated per the manufacturer and our own specifications, and tested by QSI for internal consistency for every mission using proprietary methods.

The NOAA Office for Coastal Management (OCM) received the files in laz format. The files contained Lidar elevation and intensity measurements. The data were in UTM zone 11 (NAD83 2011 Epoch 2010.0), meters coordinates and NAVD88 (Geoid12a) vertical meters. OCM performed the following processing to the data to make it available within the Digital Coast:
1. The data were converted from UTM zone 11 coordinates to geographic coordinates.
2. The data were converted from NAVD88 (orthometric) heights to NAD83(2011) ellipsoid heights using Geoid12a grids.
The data was received without a metadata record. This record was produced based on the data quality report.
2017-07-01T00:00:00
The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID18) meters, using the GEOID18 grids provided by the National Geodetic Survey.
Any datum and projection transformations were then done with the Office for Coastal Management 'datum_shift' program. Compression to an LAZ file was done with the LAStools 'laszip' program and can be unzipped with the same free program (laszip.org)
