Data were collected in shore-parallel lines, flying at approximately 50 meters per second and capturing true color imagery at 1 Hertz, resulting in image footprints with approximately 75-80% endlap, 60-70% sidelap, and a ground sample distance (GSD) of 5.3 centimeters. The precise time of each image capture (flash event) was recorded, and the corresponding aircraft position was computed in post-processing from the aircraft navigation GNSS data; precise image positions can then be determined by accounting for the lever arm offsets between the aircraft GNSS antenna and the camera lens. Position data, provided as latitude/longitude/ellipsoid height, is referenced to the North American Datum of 1983 (NAD83(2011)).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9K23VGX", "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.647e2d80d34eac007b55e38d.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_647e2d80d34eac007b55e38d", "keyword": ["CMHRP", "Cape Henlopen", "Cape Henlopen State Park", "Coastal and Marine Hazards and Resources Program", "Delaware", "Delaware Seashore State Park", "Structure-from-Motion", "U.S. Geological Survey", "USGS", "USGS:647e2d80d34eac007b55e38d", "aerial photography", "coastal processes", "earth sciences", "geography", "geomorphology", "geoscientificInformation", "geospatial datasets", "image collections", "imageryBaseMapsEarthCover", "oceans", "remote sensing", "topographic maps", "topography"], "modified": "2023-08-21T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-75.10293262, 38.44592044, -75.04850167, 38.81077614", "theme": ["geospatial"], "title": "Delaware Atlantic coast, 2022 - Aerial Imagery"}
