The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. This Hatches, NT, 1981 (P468), radiometric line data, AWAGS levelled were acquired in 1981 by the NT Government, and consisted of 9087 line-kilometres of data at 400m line spacing and 150m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS. {"type": "Polygon", "coordinates": [[[134.8734, -21.1707], [135.5941, -21.1707], [135.5941, -20.3382], [134.8734, -20.3382], [134.8734, -21.1707]]]} 134.8734 135.5941 -21.1707 -20.3382 AWAGS Australia EARTH SCIENCES Earth sciences GADDS2.0 NASVD NT Published_External airborne digital data gamma-ray geophysical survey geophysics line potassium radiometrics spectrometry survey 468 thorium uranium vector File available for download in various formats from the GADDS2 portal documentDigital The Geophysical Archive Data Delivery System (GADDS2) portal provides HTTP download of geophysics datasets in a number of formats.
