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.
