Images were acquired using a Ricoh GR II camera mounted in a near-nadir orientation in the wing of a fixed-wing aircraft, flying approximately 1,500' above ground level. Ground control consisted of 53 chalked X's on gravel surfaces, with centriod positions measured using RTK-GNSS. All photo and ground control processing was performed in Agisoft Photoscan", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F72B8W7M", "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.58c03db9e4b014cc3a3bb928.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_58c03db9e4b014cc3a3bb928", "keyword": ["Nooksack River", "USGS:58c03db9e4b014cc3a3bb928", "elevation", "elevation data", "geoscientificInformation", "photogrammetry", "structure from motion", "topography"], "modified": "2020-08-27T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-122.478104404, 48.796097104, -122.135238997, 48.948493891", "theme": ["geospatial"], "title": "Topographic survey of the Nooksack River using structure from motion photogrammetry, September 2015"}
