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 radiometric potassium grid has a cell size of 0.0004 degrees (approximately 41m) and shows potassium element concentration of the Gawler Craton Airborne Survey, Tranche 2, Block 8b, Billa Kalina, 2017 in units of percent (or %). The data used to produce this grid was acquired in 2017 by the SA Government, and consisted of 90584 line-kilometres of data at 200m line spacing and 60m terrain clearance. {"type": "Polygon", "coordinates": [[[135.0, -30.0], [136.5, -30.0], [136.5, -29.0], [135.0, -29.0], [135.0, -30.0]]]} 135.0 136.5 -30.0 -29.0 Australia EARTH SCIENCES Earth sciences GADDS2.0 K NCI Published_External SA airborne digital data gamma-ray geophysical survey geophysics grid potassium rad radiometrics raster spectrometry survey 1300 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.
