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. The total dose rate is due to natural sources of radiation and is computed by adding estimates of cosmic dose at ground level to the terrestrial dose. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered total dose rate grid. The Geological Survey of South Australia commissioned the Gawler Craton Airborne Survey (GCAS) as part of the PACE Copper initiative. The airborne geophysical survey was flown over parts of the Gawler Craton in South Australia. The program was designed to capture new baseline geoscientific data to provide further information on the geological context and setting of the area for mineral systems. This Tallaringa North - dose rate no nasvd grid (AWAGS) has a cell size of 0.00042 degrees (approximately 44m) and shows the total dose rate of the Tallaringa North Airborne Magnetic Radiometric and DEM Survey, SA, 2017 survey. The data used to produce this grid was acquired in 2017 by the SA Government, and consisted of 98230 line-kilometres of data at 200m line spacing and 60m terrain clearance. {"type": "Polygon", "coordinates": [[[131.4895, -29.5034], [133.5111, -29.5034], [133.5111, -27.9972], [131.4895, -27.9972], [131.4895, -29.5034]]]} 131.4895 133.5111 -29.5034 -27.9972 Australia EARTH SCIENCES Earth sciences GADDS2.0 K NCI Published_External SA Th U airborne digital data dose rate gamma-ray geophysical survey geophysics grid potassium rad radiometrics raster. rate spectrometry survey 1297 thorium total dose uranium 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.
