Lineage
Systematic geophysical surveys in Australia were first conducted by the Bureau of Mineral Resources (BMR, Geoscience Australia's predecessor) in the 1950s and have continued until the present. The survey aircraft flew at a nominal 150 metres above ground level on lines spaced at least 1500 metres apart. Since then surveys have been conducted over the whole continent for both mineral and petroleum exploration and to improve the understanding of the geology of Australia. In the 1980s State and NT geological surveys conducted airborne geophysical surveys by contract and supplied the collected data to GA for inclusion in the national geophysical databases. Since the 1990s surveys of flight line spacing of 500m or closer at a nominal 80 metres above ground level have been conducted as improvements in instrumentation and processing occurred.
