Gravity data was collected at 5 km wavelength resolution with the purpose to help characterise key undercover geological elements of the region. The project area extends approximately from the Balgo Hills region near the border with the Northern Territory through to Derby in the west. The survey was conducted by Thomson Aviation Pty Ltd with a GT-2A gravimeter and managed by GA. A total of 25,869.36 line km of data were acquired over an area of 58,040 km\u00b2.\n \nSurvey details\nSurvey Name: Tanami-King Leopold WA airborne gravity survey 2017\nState/Territory: Western Australia (WA)\nDatasets Acquired: Airborne gravity\n Geoscience Australia Project Number: P1291B\n Acquisition Start Date: June 16, 2017\n Acquisition End Date: August 12, 2017\n Flight line spacing: 2.5 km\n Flight line direction: 180deg / NS\n Tie line spacing: 25km\n Tie line direction: 270 deg / EW\nTotal line kilometers: 25,869.36\n Nominal terrain clearance (above ground level): 477 m\n Aircraft type: GippsAero GA-8 Airvan\nData Acquisition: Thomson Aviation \n Project Management: Geoscience Australia\n Quality Control: CMG Operations Pty Ltd and Geoscience Australia\n Dataset Ownership: GSWA and Geoscience Australia\n \nFiles included in this download\nThis data package release contains the final survey deliverables received from the contractor Thomson Aviation.
