Digital Elevation data record the terrain height variations from the processed point-located data recorded during a geophysical survey. The data acquired are a mass of ground heights representing a terrain surface. The data are either geoidal (representing the vertical distance from a location on the Earth's surface to the geoid) or ellipsoidal (representing the vertical distance from a location on the Earth's surface to the ellipsoid). The data are given in units of meters. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

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 with rigorous corrections 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 web service delivers the geographical extents and descriptive metadata of geophysical datasets from all surveys conducted or managed by Geoscience Australia and its predecessor agencies, as well as from State and Territory geological survey agencies. Datasets include gravity, magnetic, radiometric, and electromagnetic data, and elevation data collected during geophysical surveys.
