This data release provides digital flight line data for a high-resolution airborne radiometric survey over parts of northwestern Minnesota near the town of Mentor. The airborne survey was funded by the Earth Mapping Resources Initiative and was designed to meet complementary needs related to geologic mapping and characterization of mineral resource potential. A total of 40,139-line km of radiometric data were acquired over an irregular-shaped area of 9140 km2. Data were collected from a fixed-wing aircraft flown at mean terrain clearance of 120 meters (m) above topography along N-S flight lines spaced at 250 m intervals. Tie lines were flown in an E-W direction every 2500 m. Data were collected by EDCON-PRJ and NV5 Geospatial, Inc. under contract with the USGS using a fixed wing aircraft with a fully calibrated gamma-ray spectrometer. The survey operated out of the Crookston, Minnesota airport from May of 2021 to July of 2021. Files that are available in this child item include data for the radiometric survey and geotiffs of the gridded results.

This data release child item contains digital flight line data for a high-resolution radiometric survey over an area of northwest Arkansas. The airborne geophysical survey was jointly funded by the USGS National Cooperative Geologic Mapping Program and the Earth Mapping Resource Initiative and was designed to meet the complimentary needs related to geologic mapping and mineral resource research. The survey covers an irregular area 225 by 110 kilometers over the transition between the Ouachita and Ozarks Plateau physiographic provinces and includes 67,614 line-kilometers of radiometric data. Data were collected from a fixed-wing aircraft flown at mean terrain clearance of 167 meters above topography along N-S flight lines spaced at 200 meter intervals. Tie lines were flown in an E-W direction every 3000 meters. Data were collected by EON Geosciences under contract with the USGS using a fixed wing aircraft with a fully calibrated gamma-ray spectrometer. The survey operated out of the Branson, Missouri airport from October of 2019 to March of 2020.
