Airborne Gravity 2010 - Geoscience Australia

Airborne Gravity 2010
It is envisaged that the Kauring test site will facilitate the comparison of AG and AGG data with ground
gravity data (or products derived from these data) and will provide a benchmark for the comparison of
different AG and AGG systems, as well as other airborne surveying methods including LiDAR and EM
systems (Figure 7). As various test data sets become available for public distribution, they will
constitute an increasingly valuable resource for developing and demonstrating data processing,
modelling and interpretation methods for AG, AGG and other airborne geophysical data types.
The Western Australian government is proud to have been able to facilitate the establishment of what
may be the first publicly accessible airborne gravity and gravity gradiometer test range in the world
through its Exploration Incentive Scheme and in cooperation with industry (RTX) and the
Commonwealth (GA). GSWA and GA encourage companies to perform system tests over the site and
to submit their results for inclusion in the database.
Figure 8. Stacked 3D colour draped images for the airborne gravity gradiometer test site area.
The bounding box has horizontal extent of approximately 12 by 12 km. From the bottom upwards,
the images are surface topography, Complete Bouguer vertical gravity for ground measurements,
vertical gravity gradient data simulated from the ground vertical gravity data for a terrain
clearance of 80 m, and total magnetic intensity. Image kindly supplied by RTX.
