			<abstract> Product: South Central Pennsylvania 2017 QL2 LiDAR Intensity Imagery.
				Geographic Extent: 13 counties in Pennsylvania, covering approximately 6,602 total
				square miles. Dataset Description: The South Central Pennsylvania 2017 QL2 LiDAR
				project called for the planning, acquisition, processing, and derivative products of
				lidar data to be collected at a nominal pulse spacing (NPS) of 0.7 meters. Project
				specifications are based on the U.S. Geological Survey National Geospatial Program
				Base LiDAR Specification, Version 1.2. The data were developed based on a horizontal
				projection/datum of NAD 1983 (2011), UTM Zone 18, meters and vertical datum of NAVD
				1988 (GEOID 12B), meters. LiDAR data were delivered as processed Classified LAS 1.4
				files formatted to 7,975 individual 1,500-meter x 1,500-meter tiles, as tiled
				intensity imagery, and as tiled bare earth DEMs; all tiled to the same 1,500-meter x
				1,500-meter schema. Continuous breaklines were produced in Esri file geodatabase
				format. Ground Conditions: LiDAR was collected in fall 2017, while no snow was on
				the ground and rivers were at or below normal levels. In order to post process the
				LiDAR data to meet task order specifications and meet ASPRS vertical accuracy
				guidelines, Quantum Spatial, Inc. utilized a total of 150 ground control points that
				were used to calibrate the LiDAR to known ground locations established throughout
				the project area. An additional 245 independent accuracy checkpoints, 142 in Bare
				Earth and Urban landcovers (142 NVA points), 103 in Tall Weeds categories (103 VVA
				points), were used to assess the vertical accuracy of the data. These checkpoints
				were not used to calibrate or post process the data.</abstract>
			<purpose>To acquire detailed surface elevation data for use in conservation planning,
				design, research, floodplain mapping, dam safety assessments and elevation modeling,
				etc. Classified LAS files are used to show the manually reviewed bare earth surface.
				This allows the user to create intensity images, breaklines and raster DEMs. The
				purpose of these LiDAR data was to produce high accuracy 3D hydro-flattened digital
				elevation models (DEMs) with a 1-meter cell size. These raw LiDAR point cloud data
				were used to create classified LiDAR LAS files, intensity images, 3D breaklines, and
				hydro-flattened DEMs as necessary.</purpose>

				<procdesc>Intensity Image Generation Processing: GeoCue software was used to create
					the deliverable intensity images. All overlap classes were ignored during this
					process. This helps to ensure a more aesthetically pleasing image. The GeoCue
					software was then used to verify full project coverage as well. TIF/TWF files
					were then provided as the deliverable for this dataset requirement.</procdesc>
