The underwater images were processed using Structure-from-Motion (SfM) photogrammetry techniques into a classified two-class ('unclassified' and 'low noise') 3D point cloud. The DEM was created in Metashape (ver. 1.6.6) from the point cloud, and includes points from both classes. The DEM covers a rectangular area of seafloor approximately 650x120 meters (0.078 square kilometers) in size and was saved as a GeoTIFF raster at 1-centimeter resolution.", "distribution": [{"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.23c5d88d-9fd9-4779-a3f6-b19db2beb503.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9R47TWT", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_23c5d88d-9fd9-4779-a3f6-b19db2beb503", "keyword": ["Coastal and Marine Hazards and Resources Program", "visible light imaging", "geospatial datasets", "Big Pine Ledge", "coral reefs", "seabed", "St. Petersburg Coastal and Marine Science Center", "oceans", "reef ecosystems", "State of Florida", "USGS:23c5d88d-9fd9-4779-a3f6-b19db2beb503", "Pacific Coastal and Marine Science Center", "U.S. Geological Survey", "SPCMSC", "elevation", "USGS", "structure from motion", "CMHRP", "PCMSC", "Physical Habitats and Geomorphology", "remote sensing"], "modified": "2024-04-26T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-81.38473899, 24.55159193, -81.37753283, 24.55424721", "theme": ["geospatial"], "title": "Digital elevation model (DEM) of Big Pine Ledge, Florida, 2021"}
