Quantum Spatial 2016 Raster digital data Geographic Extent: Shawano County, Wisconsin, covering approximately 909 square miles. Dataset Description: The Shawano County, WI 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 UTM Zone 16, meters; NAVD1988 (Geoid 12B), meters. LiDAR data was delivered in RAW flight line swath format, processed to create Classified LAS 1.4 Files formatted to 1,143 individual 1,500-meter x 1,500-meter tiles. Tile names correspond to the US National Grid. Corresponding 1-meter gridded bare earth raster DEM files tiles were created using the same 1,500-meter x 1,500-meter schema. Hydro-flattened breaklines were produced in Esri file geodatabase as well as Esri shapefile format. Ground Conditions: LiDAR collection began in Fall 2015, 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 140 control points (40 calibration control points and 100 QC checkpoints). These were used to calibrate the LIDAR to known ground locations established throughout the project area. 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 1-meter cell size. These raw lidar point cloud data were used to create classified lidar LAS files, 3D breaklines, hydro-flattened DEMs, and contours as necessary. USGS Contract: G10PC00026 Task Order Number: G15PD00640 CONTRACTOR: Quantum Spatial Lidar data were acquired and calibrated by Quantum Spatial. All follow-on processing was completed by the prime contractor. 20151114 20151115 ground condition Complete None planned -89.244936056652 -88.2343247444778 45.0374999539153 44.5734379911025 322500.000000 402000.000000 4989000.000000 4936500.000000 None Elevation data Lidar Hydrology None Wisconsin Shawano County No restrictions apply to this data.

These raw LAS data files include all data points collected. No points have been removed or excluded. A visual qualitative assessment was performed to ensure data completeness. No void areas or missing data exist. The raw point cloud is of good quality and data passes Nonvegetated Vertical Accuracy specifications. The specifications require that Nonvegetated Vertical Accuracy (NVA) be computed for DEM files. The NVA was tested with 55 independent survey points distributed throughout the project area and located in open terrain. These checkpoints were not used in the calibration or post-processing of the lidar point cloud data. Specifications for this project require that the NVA be 19.6 cm or better AccuracyZ at 95 percent confidence level. The specifications require that Vegetated Vertical Accuracy (VVA) be computed for DEM files. The VVA was tested with 45 independent survey points distributed throughout the project area and located in vegetated terrain. These checkpoints were not used in the calibration or post-processing of the lidar point cloud data. Specifications for this project require that the VVA be 29.4 cm or better at the 95th percentile. 0.079 The NVA was tested using 55 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 DEM surface were measured for the x,y location of each check point. Elevations interpolated from the DEM surface were then compared to the elevation values of the surveyed control. The RMSEz was computed to be 0.040 meters and AccuracyZ to be 0.079 meters. This meets the required AccuracyZ value of 19.6 cm 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. 0.278 The VVA was tested using 45 independent survey points located in vegetated 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 DEM surface were measured for the x,y location of each check point. Elevations interpolated from the DEM surface were then compared to the elevation values of the surveyed control. The VVA was computed to be 0.278 meters. This meets the required value of 29.4 cm VVA at 95th percentile level using the 95th percentile of the absolute value of all vertical errors in all combined vegetation classes as defined by the National Standards for Spatial Data Accuracy (NSSDA); assessed and reported using National Digital Elevation Program (NDEP)/ASPRS Guidelines.

Hydro-Flattened Bare Earth Raster DEM Creation: Class 2 LiDAR in conjunction with the hydro breaklines were used to create a 1-meter Raster DEM. Using automated scripting routines within ArcMap, an ERDAS .IMG file was created for each tile. Each surface is reviewed using Global Mapper to check for any surface anomalies or incorrect elevations found within the surface.
