Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 Canning Basin Gravity (P195631) contains a total of 9681 point data values acquired at a spacing between 750 and 9700 metres. The data is located in WA and were acquired in 1956, under project No. 195631 for West Australian Petroleum Pty Ltd.

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. This GSWA Kurnalpi North TMI Grid Geodetic has a cell size of 0.00021 degrees (approximately 22m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2013 by the WA Government, and consisted of 92672 line-kilometres of data at 100m line spacing and 50m 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 Kurnalpi North, WA, 2013 survey were acquired in 2013 by the WA Government, and consisted of 92672 line-kilometres of data at 100m line spacing and 50m 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.
