Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data 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. These line dataset from the Murrindal, Vic, 1996 VIMP Survey (GSV3060) survey were acquired in 1995 by the VIC Government, and consisted of 15589 line-kilometres of data at 200m line spacing and 80m 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.

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. 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 terrestrial dose rate grid. This GSWA Yalgoo Doserate Grid Geodetic has a cell size of 0.00021 degrees (approximately 22m) and shows the terrestrial dose rate of the Yalgoo, WA, 2014. The data used to produce this grid was acquired in 2015 by the WA Government, and consisted of 126967 line-kilometres of data at a line spacing between 100m and 200m, and 50m terrain clearance.

This GSSA Coompana Doserate Grid Geodetic has a cell size of 0.00083 degrees (approximately 86m) and shows the terrestrial dose rate of the Coompana, SA, 2015. The data used to produce this grid was acquired in 2015 by the SA Government, and consisted of 286817 line-kilometres of data at a line spacing between 200m and 400m, and 80m terrain clearance.

This radiometric potassium grid has a cell size of 0.00083 degrees (approximately 91m) and shows potassium element concentration of the Dunmarra, NT, 2014 in units of percent (or %). The data used to produce this grid was acquired in 2014 by the NT Government, and consisted of 104017 line-kilometres of data at 400m line spacing and 80m terrain clearance.

The Digital Elevation Model represents ground surface topography between points of known elevation. The elevation data was calculated using the altimeters and Global Positioning System (GPS) sensor used for the benefit of airborne magnetic and radiometric data on the same survey. The elevation is the height relative to the Australian Height Datum GDA94 (AUSGEOID09). The processed elevation data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. These line dataset from the Morris-Cobb, WA, 2010 (South Canning 2) survey were acquired in 2010 by the WA Government, and consisted of 134843 line-kilometres of data at 400m line spacing and 60m terrain clearance.
