  "description": "The NOAA Thunder Bay National Marine Sanctuary (NMS) Topobathymetric Project Lidar data were collected by NV5 using Leica Chiroptera-5 and HawkEye-5 systems. The NOAA Thunder Bay H14138 Topobathymetric Lidar survey acquisition was flown between 20250718 and 20250726 in five missions. \nThe derived topobathymetric bare earth digital elevation model (DEM) raster mosaics were provided in Cloud Optimized GeoTIFF format with 1 meter pixel resolution, IGLD85 Low Water Datum elevations, and were delineated into 26 - 5000 meter x 5000 meter DEM tiles clipped to the 100 meter buffered project boundary covering an area of 35,166 acres. The  raster mosaics were referenced to the NAD83(2011) epoch:2010 horizontal geodetic datum, with International Great Lakes Datum 85 (IGLD85) Low Water Datum Heights, and are projected in UTM Zone 17 North coordinates.\n\nThe NOAA Office of Coast Survey (OCS) provided this data to the NOAA Office for Coastal Management (OCM) for the purpose of making the data publicly available for bulk and custom downloads from the NOAA Digital Coast Data Access Viewer.",
