The underwater images were processed using 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 850x160 meters (m) (0.13 square kilometers [km]) in size. This \"quicklook\" version of this dataset was saved as a Geographic Tagged Image File Format (GeoTIFF) raster at 1-meter resolution, so that users can quickly view the entire dataset at a lower resolution before downloading the higher resolution raster tiles. The tiled, 1-centimeter (cm) high-resolution version of the DEM is also included in this data release.", "distribution": [{"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.afe08aa6-3ecb-40f6-9b0d-b77e96b1664d.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P1QRS3SK", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_afe08aa6-3ecb-40f6-9b0d-b77e96b1664d", "keyword": ["Coastal and Marine Hazards and Resources Program", "USGS:afe08aa6-3ecb-40f6-9b0d-b77e96b1664d", "visible light imaging", "geospatial datasets", "coral reefs", "seabed", "St. Petersburg Coastal and Marine Science Center", "oceans", "reef ecosystems", "State of Florida", "Looe Key", "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": "2024-08-14T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-81.41016166, 24.54442068, -81.40065243, 24.54779751", "theme": ["geospatial"], "title": "Quicklook Digital Elevation Model (DEM) of Looe Key, Florida, 2022"}
