An orthoimage is a uniform-scale image where corrections have been made for feature displacement such as building tilt and for scale variations caused by terrain relief, sensor geometry, and camera tilt. A mathematical equation based on ground control points, sensor calibration information, and a digital elevation model is applied to each pixel to rectify the image to obtain the geometric qualities of a map.\nA digital orthoimage may be created from several photographs mosaicked to form the final image. The source imagery may be black-and-white, natural color, color infrared, or color near infrared (4-band) with a pixel resolution of 1-meter or finer. With orthoimagery, the resolution refers to the distance on the ground represented by each pixel.\n'", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F73X84W6", "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.EROS5e83a2397d63a400.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_EROS5e83a2397d63a400", "keyword": ["Aerial Photography", "Black-and-White", "Color Infrared", "Color Near-Infrared", "Georeferenced", "High Resolution Orthoimagery", "NGDA", "NGDA Imagery Theme", "NGDAID187", "National Geospatial Data Asset", "Natural Color", "Orthorectified", "Photographs", "USGS:EROS5e83a2397d63a400"], "modified": "2024-01-22T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-180, 90, 180, -90", "theme": ["geospatial"], "title": "High Resolution Orthoimagery Collection \u2013 Historical"}
