Woolpert, Inc. 20120626 Unknown vector digital data Shelby TN 1m NPS LiDAR and Feature Extraction TASK NAME: Shelby Tennessee 1m NPS LiDAR and Feature Extraction LiDAR Data Acquisition and Processing Production Task USGS Contract No. G10PC00057 Task Order No. G12PD00127 Woolpert Order No. 72124 CONTRACTOR: Woolpert, Inc. LiDAR data is a remotely sensed high resolution elevation data collected by an airborne platform. The LiDAR sensor uses a combination of laser range finding, GPS positioning, and inertial measurement technologies. The LiDAR systems collect data point clouds that are used to produce highly detailed Digital Elevation Models (DEMs) of the earth's terrain, man-made structures, and vegetation. The task required the LiDAR data to be collected at a nominal pulse spacing (NPS) of 1.0 meter. The final products include first, last, and at least one intermediate return LAS, full classified LAS and one (1) meter pixel raster DEMs of the bare-earth surface in IMG Format. The LiDAR data was acquired on January 23, 2012 and January 24, 2012. Additionally, this task required 2-D building feature extraction (building footprint) for 560 square miles of the Shelby County Tennessee AOI. The data for the Shelby County, TN task order was merged with the V13 deliverables and 2D building footprints from the Memphis, TN Task Order. This task order consisted of LiDAR data acquisition and processing for the USGS. The task required the LiDAR data to be collected at a nominal pulse spacing (NPS) of 1.0 meter. The LiDAR data was provided in 1,500 meters x 1,500 meters tiles in the UTM projection. The 1,500 meters x 1,500 meters LiDAR tile file name was derived from the southwest corner of each tile. The tiles are named based on the US National Grid. 20120123 unknown 20120124 ground condition Complete As needed -90.351165 -89.631927 35.415773 34.922025 None LiDAR LAS None United States Tennessee Shelby No restrictions apply to this data.

Using a LH Systems Light Detection And Ranging (LiDAR) system, 71 flight lines of high density data, at a nominal pulse spacing (NPS) of 1.0 meter, were collected in and near Shelby County Tennessee (approximately 798 square miles). Multiple returns were recorded for each laser pulse along with an intensity value for each return. A total of four (4) missions were flown on January 23, 2012 and January 24, 2012. A single airborne global positioning system (GPS) base station was used in support of the LiDAR data acquisition. 21 ground control points were surveyed through static methods. The geoid used to reduce satellite derived elevations to orthometric heights was Geoid09. Data for the task order is referenced to the UTM Zone 16N, North American Datum of 1983 (NAD83), and NAVD88, in Meters. Airborne GPS data was differentially processed and integrated with the post processed IMU data to derive a smoothed best estimate of trajectory (SBET). The SBET was used to reduce the LiDAR slant range measurements to a raw reflective surface for each flight line. The coverage was classified to extract a bare earth digital elevation model (DEM) and separate last returns. In addition to the LAS deliverables, one layer of coverage was delivered in the ArcINFO ArcGrid binary format: bare-earth.

Dayton OH 45430 USA (937) 461-5660 (937) 461-0743 8:00 a.m. to 5:00 p.m. Eastern Time The ALS50 calibration and system performance is verified on a periodic basis using Woolpert's calibration range. The calibration range consists of a large building and runway. The edges of the building and control points along the runway have been located using conventional survey methods. Inertial measurement unit (IMU) misalignment angles and horizontal accuracy are calculated by comparing the position of the building edges between opposing flight lines. The scanner scale factor and vertical accuracy is calculated through comparison of LiDAR data against control points along the runway. Field calibration is performed on all flight lines to refine the IMU misalignment angles. IMU misalignment angles are calculated from the relative displacement of features within the overlap region of adjacent (and opposing) flight lines. The raw LiDAR data is reduced using the refined misalignment angles. 20111130 1200 Woolpert, Inc. Geospatial Services mailing and physical address

The GPS and IMU data was post processed using differential and Kalman filter algorithms to derive a best estimate of trajectory. The quality of the solution was verified to be consistent with the accuracy requirements of the project. 20120124 1200 Woolpert, Inc. Geospatial Services mailing and physical address

Dayton OH 45430 USA (937) 461-5660 (937) 461-0743 8:00 a.m. to 5:00 p.m. Eastern Time The individual flight lines were inspected to ensure the systematic and residual errors have been identified and removed. Then, the flight lines were compared to adjacent flight lines for any mismatches to obtain a homogenous coverage throughout the project area. The point cloud underwent a classification process to determine bare-earth points and non-ground points utilizing "first and only" as well as "last of many" LiDAR returns. This process determined bare-earth points (Class 2), Noise (Class 7), Water (Class 9) Ignored ground (Class 10) and unclassified data (Class 1). The bare-earth (Class 2 - Ground) LiDAR points underwent a manual QA/QC step to verify that artifacts have been removed from the bare-earth surface. The surveyed ground control points are used to perform the accuracy checks and statistical analysis of the LiDAR dataset. 20120301 1200 Woolpert, Inc.

Breaklines defining water bodies and streams were compiled for this task order. The breaklines were used to perform the hydrologic flattening of water bodies, and gradient hydrologic flattening of double line streams. Lakes, reservoirs and ponds, at a nominal minimum size of two (2) acres or greater, were compiled as closed polygons. The closed water bodies were collected at a constant elevation. Rivers and streams, at a nominal minimum width of 30.5 meters (100 feet), were compiled in the direction of flow with both sides of the stream maintaining an equal gradient elevation. The hydrologic flattening of the LiDAR data was performed for inclusion in the National Elevation Dataset (NED). 20120420 1200 Woolpert, Inc. Geospatial Services mailing and physical address
