Woolpert Inc 20171031 Raster digital data Product: These are Digital Elevation Model (DEM) data for Indiana Statewide Lidar 2017 B17 Base Option as part of the required deliverables for the Indiana Statewide Lidar 2017 B17 Base Option Lidar project. Class 2 (ground) lidar points in conjunction with the hydro breaklines and bridge breaklines were used to create a 2.5 US Feet hydro-flattened Raster DEM. Geographic Extent: AOI is located in NE Indiana. The area of interest covers approximately 4,690 square miles. Dataset Description: Indiana Statewide Lidar 2017 B17 Base Option Lidar project called for the Planning, Acquisition, processing and derivative products of lidar data to be collected at a nominal pulse spacing (NPS) of 0.70 meter. 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 (HARN), StatePlane Indiana EastFIPS 1301, and vertical datum of NAVD88 (GEOID12B), US Feet. Lidar data was delivered as flightline-extent unclassified LAS swaths, as processed Classified LAS 1.4 files, formatted to 5,230 individual 5,000 US Feet x 5,000 US Feet tiles in NAD83 (HARN), StatePlane Indiana East FIPS 1301, US Feet as tiled Intensity Imagery, and as tiled bare earth DEMs; all tiled to the same 5,000 US Feet x 5,000 US Feet schema. Ground Conditions: Lidar was collected in early 2017 by Woolpert, 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 a total of 265 ground control points that were used to calibrate the lidar to known ground locations established throughout the project area. Additional independent accuracy checkpoints were collected (84 NVA points and 64 VVA points) 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.

None. However, users should be aware that temporal changes may have occurred since this dataset was collected and that some parts of these data may no longer represent actual surface conditions. Users should not use these data for critical applications without a full awareness of its limitations. Acknowledgement of the U.S. Geological Survey would be appreciated for products derived from these data. Data covers the entire area specified for this project. Datasets contain complete coverage of tiles. No points have been removed or excluded. A visual qualitative assessment was performed to ensure data completeness. There are no void areas or missing data. The raw point cloud is of good quality and data passes Non-Vegetated Vertical Accuracy specifications. This data set was produced to meet ASPRS Positional Accuracy Standard for Digital Geospatial Data (2014) for a 10-cm RMSEz Vertical Accuracy Class. Hydro Flattened Raster DEM Process: Class 2 (ground) lidar points in conjunction with the hydro breaklines as well bridge breaklines were used to create a 2.5 US Feet hydro-flattened Raster DEM. Using automated scripting routines within ArcMap, an ERDAS Imagine 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. 20170308 Raster NAD 1983 HARN StatePlane Indiana East FIPS 1301 0.9999666666666667 -85.66666666666667 37.5 328083.3333333333 820208.3333333333 row and column 2.5 2.5 US Feet D North American 1983 HARN GRS 1980 6378137.0 298.257222101 North American Vertical Datum of 1988 0.01 US Feet Explicit elevation coordinate included with horizontal coordinates USGS/NGTOC mailing and physical address
