All data starts the process as Class 1 (Unclassified), and then through automated classification routines, the classifications are determined using macro processing. The classes used in the dataset are as follows and have the following descriptions:\r\n\t\t\t\t\r\n\t\t\t\tClass 1 Processed, but Unclassified = These points would be the catch all for points that do not fit any of the other deliverable classes.

Points are moved to this class from the Class 2 dataset. This class is ignored during the DEM creation process in order to provide smooth transition between the ground surface and hydro flattened surface.\r\n\t\t\t\tClass 21 Snow = (Where reliably identified)\r\n\t\t\t\tClass 22 Temporal Exclusion = (Typically non-favored data in inter-tidal zones)</attraccr>\r\n    </attracc>\r\n    <logic>Checks were performed to ensure the data files can be opened, are georeferenced properly, and cover the geographic area completely. Additionally, field survey checkpoints are obtained to evaluate the accuracy of LiDAR products. As specified in the American Society for Photogrammetry and Remote Sensing (ASPRS) Positional Accuracy Standards for Digital Geospatial Data, checkpoints in vegetated and non-vegetated areas are tested in a project area. A statistical analysis between the difference in elevations of the field survey checkpoints and LiDAR-derived, bare earth elevations at the same locations provides a quality assessment of the LiDAR data.</logic>\r\n    <complete>The bare earth surface data is an estimation of the bare earth surface and does not include vegetative and built features. Likewise, it contains estimates of water edges at the time of data collection, and may not reflect current conditions. The bare earth LiDAR classification will contain voids where above ground features have been filtered out of the ground layer, including beneath buildings, motor vehicles, bridges, etc. Voids in the bare earth may also occur where insufficient energy was reflected from the surface to generate a valid return from the terrain. These types of voids in the bare earth surface tend to occur in heavily vegetated areas and over water bodies. Fresh or wet asphalt, wet sand and certain types of vegetation can also cause voids or anomalous elevations. Ground voids are interpolated in the derived terrain and Digital Elevation Model (DEM) products unless otherwise specified. The data may have been further processed to reclassify points found to be within delineated water bodies. Low confidence areas are delineated and provided in a separate dataset.</complete>\r\n    <posacc>\r\n      <horizpa>\r\n        <horizpar>Horizontal error in LiDAR derived elevation data is largely a function of positional error as derived from the Global Navigation Satellite System (GNSS), attitude (angular orientation) error (as derived from the INS) and flying altitude; and can be estimated based on these parameters to determine positional accuracy of a dataset with respect to a horizontal datum.  According to the National Standards for Spatial Data Accuracy (NSSDA), horizontal (radial) accuracy at the 95-percent confidence level is defined as Accuracyr (ACCr) where ACCr = 1.7308 x Root Mean Square Error (RMSEr).  Only photo-identifiable checkpoints in the intensity imagery can be used to test the horizontal accuracy of the LiDAR.  Photo-identifiable checkpoints in intensity imagery typically include checkpoints located at the ends of paint stripes on concrete or asphalt surfaces or checkpoints located at 90 degree corners of different reflectivity, e.g. a sidewalk corner adjoining a grass surface.  The xy coordinates of checkpoints, as defined in the intensity imagery, are compared to surveyed xy coordinates for each photo-identifiable checkpoint.  These differences are used to compute the tested horizontal accuracy of the lidar.  As not all projects contain photo-identifiable checkpoints, the horizontal accuracy of the LiDAR cannot always be tested.</horizpar>\r\n        <qhorizpa>\r\n          <horizpav>0.0</horizpav>\r\n          <horizpae>2008 EarthScope Yakima LiDAR Project\r\n\t\t\t\t\tHorizontal accuracy not explicitly reported within Lidar project documentation/metadata.</horizpae>\r\n        </qhorizpa>\r\n        <qhorizpa>\r\n          <horizpav>0.0</horizpav>\r\n          <horizpae>2014 Naches Yakima LiDAR Project\r\n\t\t\t\t\tHorizontal accuracy not explicitly reported within Lidar project documentation/metadata.</horizpae>\r\n        </qhorizpa>\r\n        <qhorizpa>\r\n          <horizpav>0.12</horizpav>\r\n          <horizpae>2014 Yakima Wetlands LiDAR Project\r\n\t\t\t\t\tHorizontal Positional Horizontal Accuracy reported as 12 cm at a 95% confidence level.</horizpae>\r\n        </qhorizpa>\r\n        <qhorizpa>\r\n          <horizpav>0.0</horizpav>\r\n          <horizpae>2015 OLC Yakima and Benton WA LiDAR Project\r\n\t\t\t\t\tHorizontal accuracy not explicitly reported within Lidar project documentation/metadata.</horizpae>\r\n        </qhorizpa>\r\n        <qhorizpa>\r\n          <horizpav>0.05</horizpav>\r\n          <horizpae>2018 Yakima Basin LiDAR Project\r\n\t\t\t\t\tHorizontal Positional Horizontal Accuracy reported as 5 cm at a 95% confidence level.</horizpae>\r\n        </qhorizpa>\r\n        <qhorizpa>\r\n          <horizpav>0.24</horizpav>\r\n          <horizpae>2018 Columbia Valley WA LiDAR Project\r\n\t\t\t\t\tHorizontal Positional Horizontal Accuracy reported as 24 cm at a 95% confidence level.</horizpae>\r\n        </qhorizpa>\r\n        <qhorizpa>\r\n          <horizpav>0.23</horizpav>\r\n          <horizpae>2019 Eastern Cascades WA LiDAR Project\r\n\t\t\t\t\tHorizontal Positional Horizontal Accuracy reported as 23 cm at a 95% confidence level.</horizpae>\r\n        </qhorizpa>\r\n      </horizpa>\r\n      <vertacc>\r\n        <vertaccr>The vertical accuracy of the source lidar and final bare earth DEMs was tested with independent survey checkpoints.  The survey checkpoints are evenly distributed throughout the project area and are located in areas of non-vegetated terrain, including bare earth, open terrain, and urban terrain, and vegetated terrain, including forest, brush, tall weeds, crops, and high grass.  The vertical accuracy of the LiDAR is tested by comparing survey checkpoints to a triangulated irregular network (TIN) that is created from the LiDAR ground points.  The accuracy results reported for the overall project are the accuracy results of the source LiDAR.   All checkpoints located in non-vegetated terrain were used to compute the Non-vegetated Vertical Accuracy (NVA).  Project specifications required a NVA of 19.6 cm at the 95% confidence level based on RMSEz (10 cm) x 1.9600.  All checkpoints located in vegetated terrain were used to compute the Vegetated Vertical Accuracy (VVA).  Project specifications required a VVA of 29.4 cm based on the 95th percentile.</vertaccr>\r\n        <qvertpa>\r\n          <vertaccv>0.0185</vertaccv>\r\n          <!-- RMSEz -->\r\n          <vertacce>2008 EarthScope Yakima LiDAR Project\r\n\t\t\t\t\t\tThis lidar dataset is compiled to meet ASPRS Positional Accuracy Standards for Digital Geospatial Data for 18.5 cm RMSEz, equating to 36.3 cm at 95% confidence level.</vertacce>\r\n        </qvertpa>\r\n        <qvertpa>\r\n          <vertaccv>0.068</vertaccv>\r\n          <!-- RMSEz -->\r\n          <vertacce>2014 Naches Yakima LiDAR Project\r\n\t\t\t\t\t\tThis data set was tested to meet ASPRS Positional Accuracy Standards for Digital Geospatial Data (2014) for a 10 (cm) RMSEz Vertical Accuracy Class.
