Average point spacing of the LAS files in the dataset are as follows:  lidar, 0.094 meters (m); multibeam sonar, 0.501 m; single-beam sonar, 1.876 m. The LAS dataset was used to create digital elevation models (DEMs) of 10 m (32.8084 feet) and 1 m (3.28084 feet) resolution, of the approximate 1.75 square kilometer surveyed area. Lidar data were collected August 22, 2022 using a boat mounted Velodyne VLP-16 unit and methodology similar to that described by Huizinga and Wagner (2019). Multibeam sonar data were collected August 22-23, 2022 using a Norbit integrated wide band multibeam system compact (iWBMSc) sonar unit and methodology similar to that described by Richards and Huizinga (2018). Single-beam sonar data were collected August 23, 2022 using a Ceescope echosounder and methodology similar to that described by Wilson and Richards (2006).This project followed similar methods to that of Wagner, Lund, and Sanks (2020), who completed a similar survey in 2019.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9Q27BD3", "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.64b52fefd34e70357a2adc06.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_64b52fefd34e70357a2adc06", "keyword": ["Bathymetry and Elevation", "DEM", "Duluth", "Great Lakes", "Hydroacoustic", "LAS", "Lake Superior", "Lidar", "Sonar", "Southwestern Lake Superior", "Superior", "USGS:64b52fefd34e70357a2adc06", "XYZ", "bathymetry", "digital elevation models", "elevation", "inlandWaters", "lidar", "limnology"], "modified": "2024-09-12T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-92.09220, 46.76260, -92.07020, 46.78400", "theme": ["geospatial"], "title": "LAS dataset of lidar, single-beam and multibeam sonar data collected at Lake Superior at Minnesota Point near the Duluth Entry, Duluth, MN, August 2022"}
