Data were processed using structure-from-motion analysis to generate a three- dimensional point cloud that identifies pixels from multiple images representing the same object and calculates the x, y, and z coordinates of that object/pixel. The point cloud was processed to create a digital surface model of the site. Finally, source images were stitched together based on shared pixels and orthogonally adjusted to create a high resolution (approximately 2 cm pixel size) orthoimage for the study area. The orthomosaic image captures conditions of a 500 m reach of the Arkansas River that includes the gaging station and nearby river banks, railroad, roads, and the Route 50 bridge over the river.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F7VT1RDH", "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.5f7408b982cef8d1839963a1.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5f7408b982cef8d1839963a1", "keyword": ["Arkansas River, Colorado", "Canon City", "Parkdale, Colorado", "SfM", "Structure from Motion", "USGS:5f7408b982cef8d1839963a1", "drone", "floodplain", "imageryBaseMapsEarthCover", "inlandWaters", "orthophotography", "remote sensing", "sUAS", "unmanned aircraft system", "unoccupied aircraft system"], "modified": "2021-01-28T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-105.3760, 38.4843, -105.3716, 38.4886", "theme": ["geospatial"], "title": "Orthorectified mosaic photograph of a portion of the Arkansas River at Parkdale, Colorado, March 2018"}
