This image was compiled from Total Magnetic Intensity survey
data held in the National Airborne Geophysical Database by
Geoscience Australia. The image is a composite of data
acquired from surveys flown by Geoscience Australia, and
surveys flown under contract to Geoscience Australia, the State
and Territory geological surveys in either separate or joint
projects and the private sector. The source data are used with
their permission. The data from these surveys were acquired at
a range of line spacings, flying heights, and measurement
accuracies.
We thank Fugro Airborne Surveys Pty Ltd for allowing the
inclusion of some proprietary data.
