Digital Airborne Magnetic and Gamma Ray Geophysical Data; BMR, Australia

The Australian Digital Airborne Geophysical Data set consists of reconnaissance measurements of magnetic field anomalies and land surface emission of gamma rays in the range 0.3-3.0 MeV. Stacked total magnetic intensity profiles with each profile base the least squares straight line fit to the navigation. Radiometric Profiles are stacked profiles of radiometric total count and total count radiometric contours. Potassium, Uranium and Thorium Profiles are stacked profiles of radiometric K, U, and Th counts. TMI Contours are Total magnetic intensity contours. The Radiometric contours usually are at a scale of 1:250000. The Gamma-ray spectrometer contours are total count contours. The Magnetic digital data is position located processed magnetic digital data. The Gamma-ray spectrometer digital data is position located processed gamma-ray digital data for K, U, Th, and total count channels. Gridded magnetic digital data is available in processed form. The data is available in ASCII format. The positional accuracy varies from 1 metre to 100 metres. To order stacked profiles and maps, contact BMR Copy Service.
