This Bathurst NSW thorium grid geodetic is an airborne-derived radiometric thorium window countrate grid for the Bathurst NSW 1991 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 thorium (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 Bathurst NSW thorium grid geodetic has a cell size of 0.0005 degrees (approximately 51m). The data are in units of counts per second (or cps). The data used to produce this grid was acquired in 1991 by the NSW Government, and consisted of 68244 line-kilometres of data at 250m line spacing and 80m terrain clearance.
