Full description

This sub-collection of the Geoscience Australia Geophysics Reference Data Collection has been compiled by Geoscience Australia from an extensive archive of over 600 airborne geophysical surveys dating back to 1953. The datasets have been acquired by Geoscience Australia and its State and Territory Government partners. The datasets primarily include processed measurements from magnetometers (magnetics) and gamma-ray spectrometers (radiometrics) mounted on fixed-wing or helicopter aircraft. Typically, these aerial surveys are flown on lines spaced regularly, in the vicinity of 50 to 1500 m apart, and at a height in the vicinity of 40 to 150 m above ground level. Ground elevation (digital elevation model) data derived from GPS height and altimeter measurement, which were acquired incidentally during many of the more recent surveys are also included. The data are processed (non-raw) and are stored in both their fundamental/original form as point-located measurements (line data), as well as in interpolated regular grid (raster) form. The collection has potential applications in a wide range of disciplines including geological mapping, mineral and petroleum resource exploration, groundwater and environmental resource management, soil science, geodesy, and infrastructure planning.
