The semi-automated classification of the imagery was accomplished by manual selection of training points representing water and non-water classes along the entire global coastline. Polygon topology was applied to the GSV, and the resulting polygons were mapped into four size classes of islands: Continental Mainlands, Big Islands (greater than 1\u2005km2), Small Islands (less than or equal to 1 km2 and greater than or equal to 0.0036 km2), and Very Small Islands (less than 0.0036 km2).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P91ZCSGM", "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.63bdf25dd34e92aad3cda273.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_63bdf25dd34e92aad3cda273", "keyword": ["USGS:63bdf25dd34e92aad3cda273", "islands"], "modified": "2023-03-01T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-180.0000, -79.9042, 180.0000, 83.6663", "theme": ["geospatial"], "title": "Global Islands"}
