The DEM has a 10-meter (32.8084 ft) cell size and was created from LiDAR data representing beach topography and sonar data representing bathymetry to a distance of approximately 1.3 kilometers (0.8 miles) offshore.  LiDAR data were collected August 10, 2019 using a boat-mounted Optech ILRIS scanner and methodology similar to that described by Huizinga and Wagner (2019).  Multi-beam sonar data were collected August 7-11, 2019 using an R2Sonic 2024 sonar unit and methodology similar to that described by Richards and Huizinga (2018).  Single-beam sonar data were collected August 27-28, 2019 using a CEESCOPE echosounder and methodology similar to that described by Wilson and Richards (2006).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9GXT1X1", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.5e389bcce4b0a79317df576f.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5e389bcce4b0a79317df576f", "keyword": ["Bathymetry and Elevation", "DEM", "Duluth", "Great Lakes", "Hydroacoustic", "LAS", "Lake Superior", "LiDAR", "Southwestern Lake Superior", "Superior", "USGS:5e389bcce4b0a79317df576f", "XYZ", "bathymetry", "digital elevation models", "elevation", "inlandWaters", "lidar", "limnology", "sonar"], "modified": "2020-08-21T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-92.05602, 46.70961, -91.99900, 46.74368", "theme": ["geospatial"], "title": "Elevation contours of beach topography and nearshore bathymetry of Lake Superior at Minnesota Point, Duluth, MN, from hydrographic survey August 2019"}
