Web Map Service of Geoscience Australia's national geophysical grids for magnetics, gravity and radiometrics - 2015 edition. The service also contains outlines and descriptions of the airborne geophysical surveys used to compile the magnetic and radiometric grids.

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. PLEASE NOTE: The layer and attribute names in this service have been modified. This may break applications and other clients with dependencies on the service. For further information please contact Geoscience Australia Client Services at clientservices@ga.gov.au.

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). Radiometrics can tell us about the distribution of certain soils and rocks. Geologists and geophysicists routinely use it as a geological mapping tool to tell them where certain rock types change. It is also useful for the study of geomorphology and soils. 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.
