As part of the National Geoscience Mapping Accord the Australian Geological Survey
Organisation flew an airborne geophysical survey of 25 394 line km over the northern half of
the Nabberu 1:250 000 Sheet of WA from 19 April to 14 March 1996. The flight line
direction was north-south and the line spacing was 400 m. Flying height was at an altitude of
80m above ground level.
The southern half of the Nabberu 1:250 00 Sheet was flown concurrently under of an AGSO
contract. Data from both suveys were merged to produce a consistent dataset for the whole
Sheet area. This report concentrates on the details regarding the survey operations and
processing of the Nabberu North survey.
The total magnetic intensity, gamma-ray spectrometric and digital elevation model data which
were collected during both surveys, have been processed and are available for purchase, in
both digital (point located data and gridded) and map form, from the Australian Geological Survey Organisation. Colour and greyscale pixel image maps are also available.
