Abstract: 
Geographic Extent: Dauphin County, Pennsylvania, covering approximately 555 square miles. 
Dataset Description: The Dauphin County, PA 2016 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 was developed based on a horizontal projection/datum of NAD83 (2011) State Plane Pennsylvania South Zone, US survey feet; NAVD1988 (Geoid 12B), US survey feet. LiDAR data was delivered in RAW flight line swath format, processed to create Classified LAS 1.4 Files formatted to 711 individual 5,000-foot x 5,000-foot tiles. Tile names use the following naming schema: "YYYYXXXXPAd" where YYYY is the first 3 characters of the tile's upper left corner Y-coordinate, XXXX - the first 4 characters of the tile's upper left corner X-coordinate, PA = Pennsylvania, and d = 'N' for North or 'S' for South. Corresponding 2.5-foot gridded hydro-flattened bare earth raster tiled DEM files and intensity image files were created using the same 5,000-foot x 5,000-foot schema. Hydro-flattened breaklines were produced in Esri file geodatabase format. Continuous 2-foot contours were produced in Esri file geodatabase format.
			Ground Conditions: LiDAR collection began in Spring 2016, 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, Quantum Spatial established a total of 84 control points (24 calibration control points and 60 QC checkpoints). These were used to calibrate the LIDAR to known ground locations established throughout the project area.
Purpose: 
Classified LAS files are used to show the manually reviewed bare earth surface. This allows the user to create breaklines and raster DEMs. The purpose of these lidar data was to produce high accuracy 3D hydro-flattened digital elevation model (DEM) with a 2.5-foot cell size. These raw lidar point cloud data were used to create classified lidar LAS files, intensity images, 3D breaklines, hydro-flattened DEMs, and contours as necessary.
Supplemental_Information: 
			USGS Contract: G10PC00016  Task Order Number: G16PD00443
			CONTRACTOR: Quantum Spatial
			Lidar data were acquired and calibrated by Quantum Spatial.
			All follow-on processing was completed by the prime contractor.
			A four-tile area around Three Mile Island required a re-flight. Steam plumes over the area limited the amount of points returned, resulting in voids in the data set. Data falling within the following tiles was re-acquired on November 22, 2016: 30502250PAS, 30502255PAS, 30002250PAS, and 30002255PAS.

Quantitative_Vertical_Positional_Accuracy_Assessment:
Vertical_Positional_Accuracy_Value:0.059
Vertical_Positional_Accuracy_Explanation: 
						The raw NVA was tested using 35 independent survey points located in open terrain. The surveyed checkpoints were distributed throughout the project area and surveyed using GNSS procedures and methodologies that provide reliable and consistent results to meet the project's accuracy requirements. Please see the "Survey Accuracy Requirements" and "Field Methodology" sections in the Survey Report for more information. Elevations from the unclassified lidar surface were measured for the x,y location of each check point. Elevations interpolated from the unclassified lidar surface were then compared to the elevation values of the surveyed control. The RMSEz was computed to be 0.099 meters (0.030 feet) and AccuracyZ to be 0.193 meters (0.059 feet). This meets the required AccuracyZ value of 19.6 cm raw NVA at 95 percent confidence level using (RMSEz * 1.9600) as defined by the National Standards for Spatial Data Accuracy (NSSDA); assessed and reported using National Digital Elevation Program (NDEP)/ASPRS Guidelines.

Process_Step:
Process_Description: 
					Lidar Pre-Processing:
					Airborne GPS and IMU data were merged to develop a Single Best Estimate (SBET) of the lidar system trajectory for each lift. Lidar ranging data were initially calibrated using previous best parameters for this instrument and aircraft. Relative calibration was evaluated using advanced plane-matching analysis and parameter corrections derived. This was repeated iteratively until residual errors between overlapping swaths, across all project lifts, was reduced to acceptable levels. Data were then block adjusted to match surveyed calibration control. Raw data NVA were checked using independently surveyed checkpoints. Swath overage points were identified and tagged within each swath file. The results of the final calibration, NVA accuracy assessments and the "raw" swaths were forwarded to the client to obtain a Notice To Proceed on classification and derivative product generation.

Process_Step:
Process_Description: 
				    Lidar Post-Processing:
				    The calibrated and controlled lidar swaths were processed using automatic point classification routines in proprietary software. These routines operate against the entire collection (all swaths, all lifts), eliminating character differences between files. Data were then distributed as virtual tiles to experienced lidar analysts for localized automatic classification, manual editing, and peer-based QC checks. Supervisory QC monitoring of work in progress and completed editing ensured consistency of classification character and adherence to project requirements across the entire project area.
				    All classification tags are stored in the original swath files.
				    After completion of classification and final QC approval, the NVA and VVA for the project are calculated. Sample areas for each land cover type present in the project area were extracted and forwarded to the client, along with the results of the accuracy tests. Upon acceptance, the complete classified lidar swath files were delivered to the client.

Process_Description: 
				    Classified LAS Creation:
				    The bare earth surface is then manually reviewed to ensure correct classification on the Class 2 (Ground) points.  After the bare-earth surface is finalized, it is then used to generate all hydro-breaklines through heads-up digitization.
				    All ground (ASPRS Class 2) LiDAR data inside of the Lake Pond and Double Line Drain hydro flattening breaklines were then classified to water (ASPRS Class 9) using TerraScan macro functionality.  A buffer of 3 feet was also used around each hydro-flattened feature to classify these ground (ASPRS Class 2) points to Ignored ground (ASPRS Class 10).  All Lake Pond Island and Double Line Drain Island features were checked to ensure that the ground (ASPRS Class 2) points were reclassified to the correct classification after the automated classification was completed.  All bridge decks were classified to Class 17.
				    All overlap data was processed through automated functionality provided by TerraScan to classify the overlapping flight line data to approved classes by USGS.  The overlap data was identified using the Overlap Flag, per LAS 1.4 specifications.
				    All data was manually reviewed and any remaining artifacts removed using functionality provided by TerraScan and TerraModeler.  Global Mapper was used as a final check of the bare earth dataset.  GeoCue was then used to create the deliverable industry-standard LAS files for both the All Point Cloud Data and the Bare Earth.  Quantum Spatial proprietary software was used to perform final statistical analysis of the classes in the LAS files, on a per tile level to verify final classification metrics and full LAS header information.

				    Hydro-Flattened Breakline Creation: 
				    Class 2 LiDAR was used to create a bare earth surface model.  The surface model was then used to heads-up digitize 2D breaklines of inland streams and rivers with a 100 foot nominal width and Inland Ponds and Lakes of 2 acres or greater surface area.
				    Elevation values were assigned to all Inland Ponds and Lakes, Inland Pond and Lake Islands, Inland Stream and River Islands, using TerraModeler functionality.
				    Elevation values were assigned to all Inland streams and rivers using Quantum Spatial proprietary software.
				    All ground (ASPRS Class 2) LiDAR data inside of the collected inland breaklines were then classified to water (ASPRS Class 9) using TerraScan macro functionality.  A buffer of 3 feet was also used around each hydro-flattened feature.  These points were moved from ground (ASPRS Class 2) to Ignored Ground (ASPRS Class 10).
				    The continuous breakline files were then translated to Esri file geodatabase format using Esri conversion tools.
