78760 il2023_10_co_dem_m13838 Data Set Published / External 49404 DEMs - partner (no harvest) Project Completed 2023 2025 A one-foot (1.0ft) cell size Digital Elevation Model (DEM) raster was created from the ground classified lidar points. The files are delivered in tile format (2000 x 2000ft), the rasters are delivered in 32-bit floating point GeoTIFF format (.tif) and adhere to USGS-NGP Lidar Base Specification 2023, rev. A. This dataset covers approximately 7454 square miles in southeast Illlinois and consists of 3 deliveries or blocks that cover all or portions of these counties: Pike, Scott, Bureau, Logan, Christian, Madison, Livingston, Ford, Kankakee, and Iroquois IL_10CoNRCS_1 (Work Unit 300580) - Approximately 3350 square miles IL_10CoNRCS_2 (Work Unit 300581) - Approximately 1992 square miles IL_10CoNRCS_3 (Work Unit 300582) - Approximately 2097 square miles This metadata record supports the data entry in the NOAA Digital Coast Data Access Viewer (DAV). For this data set, the DAV is leveraging the GeoTIFF files hosted by USGS on Amazon Web Services. This project will support the National Resources Conservation Service (NRCS) high resolution elevation enterprise program, the Illinois State Geological Survey's Height Modernization Program, and the 3DEP mission. The Defined Project Area (DPA) is represented by the USGS-provided Esri shapefile IL_10CountyNRCS_D23_DPA, and encompasses approximately 7,454 square miles, and includes all or portions of Pike, Scott, Bureau, Logan, Christian, Madison, Livingston, Ford, Kankakee, and Iroquois in the state of Illinois. Said DPA is made up of six (6) non-contiguous individual boundaries or Areas of Interest (AOIs). The Block1 area is approximately 3350 square miles and contains 23742 tiles (2000ft by 2000ft). Raster File Type = TIFF Bit Depth/Pixel Type = 32-bit float Raster Cell Size = 1.0 foot Interpolation or Resampling Technique = Triangulated Irregular Network (TIN) Required Vertical Accuracy = 19.6cm NVA Time periods have been converted from UTC to Central Standard Time for the metadata.

The lidar data set was produced to meet ASPRS “Positional Accuracy Standards for Digital Geospatial Data” (2014) for a 20.0 (cm) RMSEx / RMSEy Horizontal Accuracy Class which equates to Positional Horizontal Accuracy = +/- 49.0 cm at a 95% confidence level. This data set was produced to meet ASPRS Positional Accuracy Standard for Digital Geospatial Data (2014) for a 10-cm RMSEz Vertical Accuracy Class. USGS Determined DEM Vertical Accuracy: Non-Vegetated Vertical Accuracy (NVA) = 3.72 cm RMSE Vegetated Vertical Accuracy (VVA) = 19.52 cm at 95th Percentile The dataset was reviewed to ensure completeness and accuracy. Data covers the entire area specified for this project. The NOAA Office for Coastal Management (OCM) ingested references to the USGS GeoTIFF files that are hosted on Amazon Web Services (AWS), into the Digital Coast Data Access Viewer (DAV).
