P5023 Yathong Magnetic Gradient and Radiometric Survey, NSW, 2023

Geoscience Australia (GA), in collaboration with the New South Wales (NSW) Government’s Geological Survey of NSW, undertook a horizontal magnetic gradient and radiometric survey in the Yathong area of NSW. This survey was fully funded by the NSW Government as part of a project to find deep groundwater for use in times of drought.<br>Survey Name: YathongDatasets Acquired: Horizontal Magnetic Gradient, Radiometrics, and ElevationGeoscience Australia Project Number: P5023Acquisition Start Date: 21/05/2023Acquisition End Date: 14/09/2023Flight line spacing: 200 mFlight line direction: East-West (090-270 degrees)Total distance flown: 65,503.75 line-km'sNominal terrain clearance: 80 mData Acquisition: Magspec Airborne Surveys Pty LtdProject Management: Geoscience AustraliaQuality Control: Geoscience AustraliaDataset Ownership: Geological Survey of New South WalesDatum: Geocentric Datum of Australia 2020 (GDA2020)Projection: Map Grid of Australia Zone 55 (MGA55)<br>Included in this release:<br>1.
