The raw imagery used to create the DSM was acquired using a Canon EOS 5Dsr digital SLR camera (50.6MP Full-Frame CMOS Sensor) with attached Canon GPS Receiver GP-E2 and Canon EF 135mm f/2L USM prime telephoto lens. The helicopter circumnavigated each island at approximately 230 meters above sea level (ASL) and approximately 230 meters from the islands\u2019 coastline to provide a set of overlapping oblique images resulting in a nominal ground-sample-distance (GSD) of 1.0 centimeter. Images used f/5.6, min shutter speed 1/2500s, and max IS0 800. The data release includes a total of 638 JPG images for all 10 islands combined. The images from each island are provided in separate zip files named by island.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P14F6BIP", "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.68b71768d4be022efaf1cca2.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_68b71768d4be022efaf1cca2", "keyword": ["Oregon", "Oregon Coast National Wildlife Refuge Complex", "USGS:68b71768d4be022efaf1cca2", "aerial photography", "biota", "birds", "community ecology", "digital surface models", "elevation", "geomorphology", "geospatial datasets", "habitats", "image collections", "image mosaics", "imageryBaseMapsEarthCover", "island ecosystems", "long-term ecological monitoring", "orthophotography", "remote sensing", "structure from motion", "topography"], "modified": "2026-05-12T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-124.4280, 42.0634, -124.3199, 42.3161", "theme": ["geospatial"], "title": "Aerial imagery for 10 islands in the Oregon Coast National Wildlife Refuge Complex, OR, USA"}
