Warburton East, Warburton West, Great Victoria Desert, Kimberley Basin, Little Sandy Desert East and Little Sandy Desert West Gravity Surveys, 2018
<div>In 2018, Sander Geophysics Limited (SGL) conducted six fixed-wing high-resolution gravimetric surveys for Geoscience Australia and the Geological Survey of Western Australia. Over two hundred flights were flown to complete the planned 175,825 line kilometres, with five blocks acquired within 800 km to the northeast of Laverton and one block within 500 km to the west of Kununurra (Kimberley Basin block). The survey was flown with two aircraft utilising SGL’s airborne gravity system, Airborne Inertially Referenced Gravimeter (AIRGrav). </div><div> </div><div>The survey was funded by the Department of Mines, Industry Regulation and Safety (DMIRS) Western Australia, and managed by Geoscience Australia.</div><div><br></div><div>Survey Name: Warburton East, Warburton West, Great Victoria Desert, Kimberley Basin, Little Sandy Desert East and Little Sandy Desert West Gravity Surveys, 2018</div><div>State/Territory: Western Australia</div><div>Datasets Acquired: Airborne gravity, elevation</div><div>Geoscience Australia Project Numbers: P1312, P1313, P1315, P1316, P1317, P1318 (in the survey order above)</div><div> </div><div>Acquisition Start Date: 27 April 2018</div><div>Acquisition End Date: 04 October 2018</div><div>Flight line spacing: 2,500m</div><div>Flight line direction: East-West for Sandy Desert East and West, Kimberley Basin and Warburton East surveys, North-South for Warburton West and Great Victoria Desert surveys</div><div>Tie line spacing: 25,000 m</div><div>Tie line direction: Orthogonal to flight lines</div><div>Nominal terrain clearance: Smoother drape with nominal 160 m terrain clearance</div><div>Total distance flown: 175,825 km</div><div>Data projection: MGA51 or MGA52 using the GDA94 datum</div><div>Aircraft type: Fixed wing Cessna Grand Caravan 208B</div><div>Data Acquisition: Sander Geophysics Limited</div><div>Project Management: Geoscience Australia</div><div>Quality Control: Geoscience Australia</div><div>Dataset Ownership: Western Australia Department of Mines, Industry Regulation and Safety, and Geoscience Australia</div><div><br></div><div>Data package for the 6 sub surveys:</div><div>- Contractors Report (combined)</div><div>- Line data in XYZ and ASEG GDF format</div><div>- Read me files of datasets</div><div>- Quality control reports for each survey area</div><div>- Gridded data with details below</div><div><br></div><div>GRIDS</div><div>==============</div><div>Datum: GDA94</div><div>Projection: MGA 51 or MGA 52 </div><div>Grid cell size: 500m</div><div>Formats: Grid Exchange File (.gxf) and ERMapper (.ers)</div><div><br></div><div>Name Units Description</div><div>-------------- --------- ----------------------------------------------</div><div>GRVFAL5000M µms-2 Free air gravity, 5000 m (#) full wavelength spatial filter</div><div>FVDFAL5000M Eotvos First vertical derivative of free air gravity, 5000 m (#) full wavelength spatial filter</div><div>GRVBGL5000M_267 µms-2 Full Bouguer gravity, 5000 m (#) full wavelength spatial filter, 2670 kg/m3 density</div><div>FVDBGL5000M_267 Eotvos First vertical derivative of full Bouguer gravity, 5000 m (#) full wavelength spatial filter, 2670 kg/m3 density</div><div>GRVISO5000M_267 µms-2 Isostatic residual gravity, 5000 m (#) full wavelength spatial filter, 2670 kg/m3 density</div><div>FVDISO5000M_267 Eotvos First vertical derivative of isostatic residual gravity, 5000 m (#) full wavelength spatial filter, 2670 kg/m3 density</div><div>TERRAIN m Laser terrain (above GDA94 Ellipsoid)</div><div>BAREEARTH m Bare earth terrain (above GDA94 Ellipsoid)</div><div>----------------------------------------------------------------------------------------------------------</div><div> </div><div># 5000 m wavelength filter employed for all projects other than Little Sandy Desert West where a 2500 m wavelength filter was employed instead.

- Purpose
-
High-resolution gravity on regional/district scales is an important component of mineral and energy integrated pre-competitive approach to data collection and information to support new and ongoing industry exploration investment in Australia's resources. Such data is also invaluable for vertical positioning accuracy with industry and government agencies requiring vertical height surfaces to within 10 cm for advanced (often autonomous) operations , productivity efficiency, and safety.
