Airborne Geophysical Surveys - June 2014

This layer provides the outlines and specifications of 1085 airborne geophysical surveys conducted by or for the Australian, State and Territory governments. Most of the data for surveys referred to in this Index are available free on- line via the Geophysical Archive Data Delivery System (GADDS - http://www.geoscience.gov.au/gadds). They comprise more than 34 million line kilometres of mainly total magnetic intensity and gamma-ray spectrometric data. Land elevation data derived from GPS recordings made during airborne magnetic and gamma-ray spectrometric surveys, and electromagnetic data are also available for some areas. The associated index (Percival, P.J., 2014. Index of airborne geophysical surveys (Fourteenth Edition). Geoscience Australia Record 2014/014) contains the specifications of surveys.
