The airborne survey was funded by the\nEarth Mapping Resources Initiative.\nNV5 Geospatial, in collaboration with EDCON-PRJ, Inc.,\nacquired high-precision airborne magnetic and radiometric\ndata from November 15, 2023 to August 26, 2024. Data were collected with\na fixed wing aircraft along east-west flight lines spaced at 200 meters, and\nnorth-south tie lines spaced at 2000 meters, at a nominal terrain clearance\nof 120 meters above topography, except where rough terrain or populated\nareas required greater clearance.\nA total of 162,419 line-kilometers of magnetic and radiometric data was\nacquired along 1,040 primary survey lines and 85 tie lines.\nFiles available in this data release include the magnetic data, the\nradiometric data, and a report describing the survey parameters, field\noperations, quality control, and data processing procedures. In addition,\nZIP files are provided that contain the proprietary-format data files\ndelivered by the contractor as Geosoft databases and grids.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P1GGHK8X", "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.68018832d4be0263cab10a9b.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_68018832d4be0263cab10a9b", "keyword": ["AASG", "Aeroradiometric survey", "Airborne geophysical survey", "Arizona", "Association of State Geologists", "Earth Mapping Resources Initiative", "EarthMRI", "Economic Geology", "GMEGSC", "Geology, Minerals, Energy, and Geophysics Science Center", "Geophysics", "Geospatial datasets", "MRP", "Mineral Resources", "Mineral Resources Program", "National Cooperative Geologic Mapping Program", "Potassium", "Sedimentology", "Structural Geology", "Thorium", "U.S. Geological Survey", "USA", "USGS", "USGS:68018832d4be0263cab10a9b", "United States", "United States of America", "Uranium", "geoscientificInformation"], "modified": "2025-05-28T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-110.854987, 33.237262, -109.035465, 31.354277", "theme": ["geospatial"], "title": "Airborne radiometric data acquired over parts of Cochise, Graham, Greenlee, Pima, Pinal, and Santa Cruz Counties, Arizona"}
