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 January 19, 2025 to September 25, 2025. 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 166,594 line-kilometers of magnetic and radiometric data was\nacquired along 1,306 primary survey lines and 141 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. Data files are\nprovided in non-proprietary formats: tables in CSV format and grids in GeoTIFF\nformat, as exported by the commercial geophysical software Oasis montaj. In addition,\nZIP files are provided that contain the data in proprietary-format files\ndelivered by the contractor as Geosoft databases (*.gdb) and grids (*.grd).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P1EOKG6I", "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.69a5c06bb66b011d83258c49.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_69a5c06bb66b011d83258c49", "keyword": ["AASG", "Aeromagnetic survey", "Aeroradiometric survey", "Airborne geophysical survey", "Association of State Geologists", "Earth Mapping Resources Initiative", "EarthMRI", "Economic Geology", "GMEGSC", "Geology, Minerals, Energy, and Geophysics Science Center", "Geophysics", "Geospatial datasets", "MRP", "Magnetic field (earth)", "Mineral Resources", "Mineral Resources Program", "National Cooperative Geologic Mapping Program", "Potassium", "Sedimentology", "Structural Geology", "Texas", "Thorium", "U.S. Geological Survey", "USGS", "USGS:69a5c06bb66b011d83258c49", "United States", "Uranium", "geoscientificInformation"], "modified": "2026-05-07T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-105.664580, 29.306309, -102.725172, 31.668181", "theme": ["geospatial"], "title": "Airborne magnetic and radiometric data acquired over parts of Hudspeth, Culberson, Jeff Davis, Presidio, and Brewster Counties, Texas"}
