Towards standard technical Deeds for (airborne) geophysical surveys in Australia

Geoscience Australia (GA) and its predecessors have been conducting geophysical surveys and processing geophysical data since the early 1950's. Over time, GA's role has changed from being a pioneer in the acquisition and processing of data to focusing on setting standards for the geophysical industry in Australia. The experience gained from conducting geophysical surveys since the 1990's is now used to ensure that any government survey is conducted to a level of quality and consistency that ensures the collected data is world-class and fit for purpose. Magnetic and radiometric technical Deeds were introduced in 2003. Suppliers on the Deed have been preapproved to provide geophysical data, processing and supply services to GA according to the requirements. The Deeds include requirements for calibration, acquisition, and processing of magnetic and radiometric data as well as data formats and reporting requirements. The Deeds provide a means for consistent and reliable magnetic and radiometric data collection. These standards also enable us to create national compilations from surveys collected by different suppliers across Australia.
