JPG files in each folder follow the following naming convention: {YYYYMMDDHHMMSS}_{SN###}_{PreservedFileName}.jpg, where {YYYYMMDDHHMMSS} is the image acquisition time in {YearMonthDayHourMinuteSecond} expressed in 24-hour time, as recorded by the camera\u2019s internal clock or subsequently adjusted and written to the DateTimeOriginal field in the image EXIF data,  {SN###} is the last 3 digits of the camera serial number OR 000 in the case the camera doesn't have a serial number, preceded by the letters \u201cSN\u201d, and {PreservedFileName} is the original filename recorded at the time the image was captured. For example, 20120319123426_SN000_IMG_1082.JPG would be the filename for an image with a DateTimeOriginal EXIF time/date stamp of March 19th, 2012, at 12:34:26 pm in Pacific Standard Time (PST) - See attribute accuracy report in platform metadata for details on time accuracy.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9M3NYWI", "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.8ad74536-ce19-4ab7-951b-b5b244803b44.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_8ad74536-ce19-4ab7-951b-b5b244803b44", "keyword": ["CMHRP", "Coastal and Marine Hazards and Resources Program", "Distributions", "Elwha River", "Elwha River Restoration Project", "NPS", "National Park Service", "Olympic National Park", "PCMSC", "Pacific Coastal and Marine Science Center", "Physical Habitats and Geomorphology", "U.S. Geological Survey", "USGS", "USGS:8ad74536-ce19-4ab7-951b-b5b244803b44", "United States", "United States and Territories", "aerial and satellite photography", "aerial photography", "agents of coastal change", "anthropogenic agents of coastal change", "coastal development", "coastal ecosystems", "coastal erosion", "coastal landslides", "coastal processes", "datasets", "earth sciences", "ecology", "environment", "geography", "geologic processes", "geology", "geoscientificInformation", "geospatial datasets", "habitat", "image analysis", "image collections", "imageryBaseMapsEarthCover", "infrastructure", "remote sensing", "slope processes", "structures", "visible light imaging"], "modified": "2025-04-09T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-123.6116314, 47.9139, -123.5048267, 48.1532687", "theme": ["geospatial"], "title": "Elwha PlaneCam - aerial imagery and derivatives from Elwha River (WA) flight on September 30th, 2014"}
