GSSA Warrina Potassium rate Grid Geodetic

This GSSA Warrina Potassium rate Grid Geodetic is an airborne-derived radiometric potassium window countrate grid for the Warrina Airborne Magnetic Radiometric and DEM Survey, SA, 2017 survey. The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). 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 GSSA Warrina Potassium rate Grid Geodetic radiometric potassium window countrate grid has a cell size of 0.00042 degrees (approximately 44m). The data are in units of counts per second (cps). The data used to produce this grid was acquired in 2017 by the SA Government, and consisted of 135932 line-kilometres of data at 200m line spacing and 60m terrain clearance.
