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 Tanami NS - radiometric line data (AWAGS) were acquired in 2018 by the NT Government, and consisted of 145230 line-kilometres of data at 200m line spacing and 60m 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": [[[128.9885, -21.2514], [131.5353, -21.2514], [131.5353, -20.1841], [128.9885, -20.1841], [128.9885, -21.2514]]]} 128.9885 131.5353 -21.2514 -20.1841 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 1312 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.
