Woolpert 20201209 Vector digital data Product: Hydro-flattened lake and river breaklines in Esri file geodatabase format, bridges used for hydro-flattening in Esri shapefile format. Geographic Extent: Approximately 18,069 square miles across the following counties in western Indiana: Benton, Boone, Carroll, Clay, Clinton, Crawford, Daviess, Dubois, Fountain, Gibson, Greene, Hendricks, Jasper, Knox, Lake, LaPorte, Lawrence, Martin, Monroe, Montgomery, Morgan, Newton, Orange, Owen, Parke, Perry, Pike, Porter, Posey, Pulaski, Putnam, Spencer, Starke, Sullivan, Tippecanoe, Vanderburgh, Vermillion, Vigo, Warren, Warrick, White. Dataset Description: The Indiana Statewide Lidar 2017 B17 West task called for the planning, acquisition, processing, and production of derivative products of lidar data to be collected at a nominal pulse spacing (NPS) of 0.7 meters. Project specifications were based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification, Version 1.2. The data was developed based on a horizontal datum/projection of NAD83 (HARN) State Plane Indiana West Zone (FIPS 1302), US Survey Feet, and a vertical datum of NAVD88 (GEOID12B), US Survey Feet. Breaklines are reviewed against lidar intensity imagery to verify completeness of capture. The compilation procedure included use of lidar intensity, bare earth surface model, point cloud data, and open source imagery in an effort to manually compile hydrologic features in a 2-D environment. Following the compilation phase, a separate process was used to adjust the breakline data to best match the water level at the time of the lidar collection. Any ponds and/or lakes were adjusted to be at or just below the bank and to be at a constant elevation. Any streams were adjusted to be at or just below the bank and to be monotonic. Manual QAQC and peer-based QC review was performed on all delineated data to ensure horizontal placement quality and on all adjusted data to ensure vertical placement quality. Bridge breaklines were also compiled in efforts to generate an accurate DEM product. The final hydrologic lake and river breakline products were delivered as polygon and polyline feature classes in an Esri file geodatabase. Bridge breaklines were delivered as point features in Esri shapefile format. Ground Conditions: Lidar was collected from March 9, 2017 through April 11, 2020 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, Woolpert established 234 ground control points that were used to calibrate the lidar to known ground locations established throughout the project area. An additional 724 independent accuracy checkpoints (417 NVA points and 307 VVA points), were collected and used to assess the vertical accuracy of the data. These checkpoints were not used to calibrate or post process the data. This project will support the state of Indiana and the Natural Resources Conservation Service (NRCS) in Indiana.

Data covers the entire area specified for this project. Breaklines were collected in all inland ponds and lakes ~2 acres or greater. These features were flat and level water bodies at a single elevation for each vertex along the bank. The entire water surface edge is at or below the immediate surrounding terrain. Breaklines were collected for all streams and rivers ~100' nominal width or wider. These features are flat and level bank to bank, gradient will follow the surrounding terrain and the water surface will be at or below the surrounding terrain. Streams/river channels will break at culvert locations however not at elevated bridge locations. All files are inspected to ensure that they conform to the specified file naming conventions, all files load in their correct geographic position, all files conform to the project specifications for file standard and content.

Woolpert 20201209 Vector digital data Dayton, OH Woolpert Digital data 20201209 ground condition Indiana Statewide Lidar 2017 B17 West - Data Extent The data extent was created in shapefile format. Hydro Breaklines: Class 2 (ground) lidar points was used to create a bare-earth surface model. The compilation procedure included use of lidar intensity, bare-earth surface model, point cloud data, and open source imagery in an effort to compile hydrologic features in a 2-D environment. Elevation values were assigned to all inland ponds and lakes, inland pond and lake islands, and inland stream and river islands, using TerraModeler/LP360 functionality. All ground (Class 2) lidar data inside of the collected inland breaklines were then classified to water (Class 9) using TerraScan macro functionality. A buffer of 1.14 feet was also used around each hydro-flattened feature. These points were moved from ground (Class 2) to Ignored Ground (Class 10). Breaklines are reviewed against lidar intensity imagery and surface models to verify completeness of capture. The horizontal placement of breaklines is compared to terrain features and the breakline elevations are compared to lidar elevations to ensure all breaklines match the lidar within acceptable tolerances. Some deviation is expected between breakline and lidar elevations due to monotonicity, connectivity, and flattening rules that are enforced on the breaklines. Once completeness, horizontal placement, and vertical variance is reviewed, all breaklines are reviewed for topological consistency and data integrity using a combination of Esri Data Reviewer tools. The final lake and river hydrologic breakline products were delivered as polygon and polyline features classes in an Esri file geodatabase. Bridge breaklines were delivered as point features in Esri shapefile format. This breakline data was used in the processing of the DEM deliverable.
