Upper Mississippi Work Unit 1; Hydro Flattened Bare Earth DEM

A half-meter (0.5m) cell size Digital Elevation Model (DEM) raster was created from the ground classified lidar points plus the breaklines. The files are delivered in tile format (1000m by 1000m), the rasters are delivered in 32-bit floating point GeoTIFF format (.tif) and adhere to USGS-NGP Lidar Base Specification 2021, rev. A.
