The area was flown along a draped surface with a nominal survey height above ground of 125 meters. The flight line spacing was 250 meters for traverse lines and 2500 meters for control lines. Here we present downloadable radiometric (gamma spectrometry) data from those surveys as flight line data (csv format) or Geotiff images.\nLine data (EAdirondacksSpec.csv) are presented as comma separated values with the following definitions (see technical report for details):\nLINE           \tFlight line number \nDATE            YYYY/MM/DD \nTIME            Time (UTM, 24-hour) hh:mm:ss \nLONG            Longitude, WGS84 (degrees) \nLAT            \tLatitude WGS84 (degrees) \nx_UTM18N    \tEasting, UTM Zone 18N (meters) \ny_UTM18N    \tNorthing, UTM Zone 18N (meters) \nRALT            Radar altimeter height (meters) \nBALT        \tBarometric altimeter height (meters) \nGPSZ        \tGPS elevation (meters)\nSTPHT\t\tStandard temperature/pressure height (m)\nTEMP\t\tTemperature (degrees C)\nBARPRES\t\tBarometric pressure (kPa)\nTOTCT           Raw total count (counts/second) \nCOSFILT\t\tLow-pass filtered cosmic count (cps)\nRADON\t\tComputed radon background (cps)\nTC_DOSE\t\tNatural air absorbed dose rate (nGy/h)\nK_PCT\t\tCorrected potassium concentration (%)\nU_PPM\t\tCorrected uranium concentration (ppm)\nTh_PPM\t\tCorrected Thorium concentration (ppm)\nGeotiff images show potassium (K), equivalent uranium (eU), equivalent thorium (eTh), dose rate and a ternary diagram showing relative abundances of K, eU, and eTh. The files are, respectively, EAdirondacks_K.tif, EAdirondacks_eU.tif, EAdirondacks_eTh.tif, EAdirondacks_Dose.tif, and EAdirondacks_Ternary.tif. Images use projected coordinates (UTM 18N, WGS84); Geotiff tags are embedded. Colorbar images and a ternary legend are provided in separate files (DatasetName_colorbar.jpg, Ternary_legend.jpg).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F72R3PT0", "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.582b9415e4b0c253be072a3d.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_582b9415e4b0c253be072a3d", "keyword": ["Adirondack Mountains", "Essex County", "New York", "USGS:582b9415e4b0c253be072a3d", "United States", "aeromagnetic maps", "aeromagnetic surveying", "aeroradiometric surveying", "airborne magnetics", "economy", "geologic mapping", "geologic maps", "geoscientificInformation", "magnetic anomaly maps", "magnetic field (earth)", "magnetics", "mineral resources", "subsurface imaging", "subsurface maps"], "modified": "2025-01-27T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-73.78, 43.70, -73.35, 44.39", "theme": ["geospatial"], "title": "Radiometric Data of Airborne Geophysical Surveys over the Eastern Adirondacks, New York State"}
