The Australian Geological Survey Organisation (AGSO) flew an airborne geophysical survey
of 69 086 line km covering the entire Cootamundra 1:250 000 map Sheet area in the Lachlan
Fold Belt of New South Wales.
The survey formed part of the National Geoscience Mapping Accord and was jointly funded
by AGSO, Department of Primary Industries and Energy and the Geological Survey, New
South Wales Department of Mineral Resources. The survey was flown along east-west flight
lines, 250 metres apart at an altitude of 80 metres above ground level. AGSO flew the survey
over two periods; from November to December 1997 and from February to March 1998.
The total magnetic intensity, gamma-ray spectrometric and digital elevation model data
collected during the survey, have been processed and are available for purchase. These data
are sold as digital point located data, grids and hardcopy maps, by the Australian Geological
Survey Organisation. Colour and greyscale pixel image maps are also available.
