The Polecam system is a single downward-looking underwater Teledyne FLIR camera with a Computar V1228-MPY lens and  with a rigidly-attached Global Navigation Satellite System (GNSS) antenna mounted directly above the camera's central axis. The pole camera was attached to the gunwale of the USGS research vessel (R/V) Sallenger. The Polecam system captured images as Tag Image File Format (TIFF, .tif) files to maintain the highest resolution and bit depth. In this data release, the files were converted into Joint Photographic Experts Group (JPEG, .jpg) file to enhance the accessibility of the imagery. Each image contains imagery header metadata embedded within the file, including GNSS date, time, latitude and longitude of the GNSS antenna, copyright, keywords, and other descriptive information. Refer to the \u2018IMAGERY HEADERS\u2019 Process Step of the metadata for more information on the imagery headers.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://cmgds.marine.usgs.gov/idsviewer/data_release/10.5066-P9KNCMFY", "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.8fa37f5c-dd94-4f14-910e-860c5615b09d.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_8fa37f5c-dd94-4f14-910e-860c5615b09d", "keyword": ["Boca Chica Key", "CMHRP", "Coastal and Marine Hazards and Resources Program", "Monroe County", "Naval Air Station Key West", "PCMSC", "Pacific Coastal and Marine Science Center", "SPCMSC", "St. Petersburg Coastal and Marine Science Center", "State of Florida", "U.S. Geological Survey", "USGS", "USGS:8fa37f5c-dd94-4f14-910e-860c5615b09d", "coral reefs", "geoscientificInformation", "imageryBaseMapsEarthCover", "location", "marine geology", "ocean characteristics", "oceans", "reef ecosystems", "seabed"], "modified": "2023-11-01T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-81.700655, 24.549621, -81.681257, 24.556835", "theme": ["geospatial"], "title": "2022-334-FA_BocaChica_Polecam_Imagery: High-resolution Geophysical and Imagery Data Collected in November 2022 Offshore of Boca Chica Key, FL"}
