        abstract:  No metadata record was provided with the data. This record is populated with information from the Quantum Spatial, Inc. technical report downloaded from the Washington Dept. of Natural Resources Washington Lidar Portal. In 2014 WSI, a Quantum Spatial (QSI) company, was contracted by Washington State Department of Natural Resources (Washington DNR) to collect Light Detection and Ranging (LiDAR) data in the Willapa River Valley site in Pacific and Lewis County in southwest Washington. The initial delivery (delivery 1) occurred in April 2014 and was for 35,472 acres. Due to weather and resource constraints, the remaining acquisition (delivery 2) was completed in December 2014 during leaf-off season. In addition to these bare earth Digital Elevation Model (DEM) data, the lidar point data that these DEM data were created from, are also available. These data are available for custom download at the link provided in the URL section of this metadata record.
        purpose:  Collect lidar elevation data.

            nameOfMeasure:  Vertical Positional Accuracy
            evaluationMethodDescription:  Absolute accuracy was assessed using Fundamental Vertical Accuracy (FVA) reporting designed to meet guidelines presented in the FGDC National Standard for Spatial Data Accuracy. FVA compares known RTK ground check point data collected on open, bare earth surfaces with level slope (<20°) to the triangulated surface generated by the LiDAR points. FVA is a measure of the accuracy of LiDAR point data in open areas where the LiDAR system has a high probability of measuring the ground surface and is evaluated at the 95% confidence interval (1.96 * RMSE). The mean and standard deviation (sigma σ) of divergence of the ground surface model from ground survey point coordinates are also considered during accuracy assessment. These statistics assume the error for x, y and z is normally distributed, and therefore the skew and kurtosis of distributions are also considered when evaluating error statistics. For the Willapa River Valley survey, 233 ground survey points were collected in total resulting in an average accuracy of -0.034 feet (-0.010 meters). Vertical RMSE = 0.110 ft (3.3 cm)

            statement:  The NOAA Office for Coastal Management (OCM) downloaded the .img files from the Washington Lidar Portal.
            processStep:  (LI_ProcessStep)
                description:  The LiDAR survey was accomplished using a Leica ALS70 system mounted in a Caravan and Partenavia aircraft. Table 6 summarizes the settings used to yield an average pulse density of greater than or equal to 8 pulses/m2 over the Willapa River Valley project area. The Leica ALS70 laser system can record unlimited range measurements (returns) per pulse, but typically does not record more than 5 returns per pulse . It is not uncommon for some types of surfaces (e.g., dense vegetation or water) to return fewer pulses to the LiDAR sensor than the laser originally emitted. The discrepancy between first return and overall delivered density will vary depending on terrain, land cover, and the prevalence of water bodies. All discernible laser returns were processed for the output dataset.
            processStep:  (LI_ProcessStep)
                description:  All areas were surveyed with an opposing flight line side-lap of greater than or equal to 50% (greater than or equal to 100% overlap) in order to reduce laser shadowing and increase surface laser painting. To accurately solve for laser point position (geographic coordinates x, y and z), the positional coordinates of the airborne sensor and the attitude of the aircraft were recorded continuously throughout the LiDAR data collection mission. Position of the aircraft was measured twice per second (2 Hz) by an on-board differential GPS unit, and aircraft attitude was measured 200 times per second (200 Hz) as pitch, roll and yaw (heading) from an on-board inertial measurement unit (IMU). To allow for post-processing correction and calibration, aircraft and sensor position and attitude data are indexed by GPS time.
            processStep:  (LI_ProcessStep)
                description:  Upon completion of data acquisition, QSI processing staff initiated a suite of automated and manual techniques to process the data into the requested deliverables. Processing tasks included GPS control computations, smoothed best estimate trajectory (SBET) calculations, kinematic corrections, calculation of laser point position, sensor and data calibration for optimal relative and absolute accuracy, and LiDAR point classification. Processing methodologies were tailored for the landscape. Brief descriptions of these tasks are below. IPAS TC v.3.1, Waypoint Inertial Explorer v.8.5 Resolve kinematic corrections for aircraft position data using kinematic aircraft GPS and static ground GPS data. Develop a smoothed best estimate of trajectory (SBET) file that blends post-processed aircraft position with sensor head position and attitude recorded throughout the survey. ALS Post Processing Software v.2.75 Calculate laser point position by associating SBET position to each laser point return time, scan angle, intensity, etc. Create raw laser point cloud data for the entire survey in *.las (ASPRS v. 1.2) format. Convert data to orthometric elevations by applying a geoid correction. TerraScan v.14 Import raw laser points into manageable blocks (less than 500 MB) to perform manual relative accuracy calibration and filter erroneous points. Classify ground points for individual flight lines. TerraMatch v.14 Using ground classified points per each flight line, test the relative accuracy. Perform automated line-to-line calibrations for system attitude parameters (pitch, roll, heading), mirror flex (scale) and GPS/IMU drift. Calculate calibrations on ground classified points from paired flight lines and apply results to all points in a flight line. Use every flight line for relative accuracy calibration. TerraScan v.14, TerraModeler v.14 Classify resulting data to ground and other client designated ASPRS classifications.
            processStep:  (LI_ProcessStep)
                description:  Generate bare earth models as triangulated surfaces. Generate highest hit models as a surface expression of all classified points. Export all surface models as ESRI GRIDs in EDRAS Imagine (.img) format at a 3.0 foot 1 meter pixel resolution. TerraScan v.14 TerraModeler v.14 ArcMap v. 10.1

                description:  No metadata record was provided with the data. This record is populated with information from the Quantum Spatial, Inc. technical report downloaded from the Washington Dept. of Natural Resources Washington Lidar Portal. The NOAA Office for Coastal Management (OCM) downloaded 8 .img format files from the Washington Lidar Portal. The bare earth raster files were at a 3 ft grid spacing. The data were in Washington State Plane South (NAD83 HARN), US survey feet coordinates and NAVD88 (Geoid03) elevations in feet. OCM assigned the appropriate EPSG codes (Horiz - 2286, Vert - 6360) and copied the raster files to https for Digital Coast storage and provisioning purposes.
