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 Coober Pedy West Airborne Magnetic Radiometric and DEM Survey, SA, 2017 survey were acquired in 2017 by the SA Government, and consisted of 90697 line-kilometres of data at 200m line spacing and 60m terrain clearance.

Gravity data measure 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 South Nicholson Gravity Survey GA P201701 CSCBA267GU is a complete spherical cap Bouguer anomaly grid for the South Nicholson Gravity Survey (P201701). This gravity survey was acquired under the project No. 201701 for the geological survey of NT. The grid has a cell size of 0.00742 degrees (approximately 800m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 2725 gravity stations were acquired to produce this grid.
