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.

Digital Elevation data record the terrain height variations from the processed SRTM surface elevation 3 second grid data with a drape surface overlain. This National Gravity Compilation 2019 Ausdrape elevation geoid image (hillshade HSI) is elevation data for the 2019 Australian National Gravity Grids B series. These data are used in the project No. 202008. The grid used to produce this image has a cell size of 0.00417 degrees (approximately 435m). All data (i.e., ground, airborne and marine derived from satellite altimetry) were vertically continued to this surface during processing. The surface was generated to mimic a smooth airborne survey drape surface with a minimum surface clearance of 250 m and an isotropic maximum climb and descent rates of 25 m per km. The ground surface data were derived from SRTM data with 3 second grid cell size. The data are given in units of meters. The data are given in units of meters.
