Class 2 (ground) LiDAR points in conjunction with the hydro breaklines were used to create a 0.5 meter hydro-flattened Raster DEM. Geographic Extent: This project covers 2 counties in Wisconsin: WI_2County_1 (Work Unit 300411) covering approximately 641 square miles in Manitowoc County WI_2County_2 (Work Unit 300412) covering approximately 718 square miles in Buffalo County Dataset Description: The WI_2County_B23 project called for the planning, acquisition, processing, and derivative products of lidar data to be collected at a nominal pulse spacing (NPS) of 0.35 meters. Project specifications are based on the U.S. Geological Survey National Geospatial Program Base LiDAR Specification, 2023 Rev. A. The data were developed based on a horizontal projection/datum of NAD 1983 2011 UTM Zone 15N and16N, meters and vertical datum of NAVD88 Geoid 18, meters. LiDAR data were delivered as processed Classified LAS 1.4 files formatted to individual 1000 m x 1000 m tiles, as tiled intensity imagery, and as tiled bare earth DEMs; all tiled to the same 1000 m x 1000 m schema. Continuous breaklines were produced in Esri file geodatabase format. Ground Conditions: LiDAR was collected in spring 2023, while no snow was on the ground and rivers were at or below normal levels. Tile 16TDP443865 is empty due to being entirely over water. 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.
