Airborne radiometric flight line data, Columbia, South Carolina and surrounds, 2020

Airborne radiometric data are provided here as part of the data release "Airborne magnetic and radiometric survey, Columbia, South Carolina and surrounds, 2020." This website includes the processed aeroradiometric data (gamma spectrometry for K, U and Th) provided in an ascii .csv file, spectral data in a binary netcdf file that can be read using the relevant Python libraries (see example included with this release), and a geoTIFF showing a ternary image of the K, Th, and U channels. The contractor report is available on the parent page. These data were collected as part of a high-resolution airborne magnetic and radiometric survey over Columbia, South Carolina and the surrounding region immediately northwest of an airborne magnetic and radiometric survey collected near Charleston, South Carolina in 2019 (Shah et al., 2020). Goals included imaging heavy mineral sands containing titanium, zirconium, and rare earth elements using radiometric data (gamma spectrometry), which is sensitive to thorium in monazite, and better understanding the buried crystalline basement rocks using magnetic data. This survey is part of the U.S. Geological Survey (USGS) Earth Mapping Resource Initiative (Earth MRI).
