Australian Geophysical Survey Lines for Magnetic, Radiometric, and Gravity Data

Geoscience Australia's collection contains individual airborne survey lines of geophysical data, including Total Magnetic Intensity, Gamma-ray spectrometry (radiometrics - K, Th, U) and elevation, as well as ground based Bouguer Gravity. The data were sourced from publicly available government- and company-acquired geophysical surveys in Australia and its surrounding marine area. These datasets have been used to create both survey scale and national grids.

Use Cases

• Mineral exploration targeting based on magnetic and radiometric anomalies.
• Regional geological mapping based on airborne survey line data.
• Gravity modeling for crustal studies based on Bouguer Gravity data.
• Environmental baseline studies based on gamma-ray spectrometry (K, Th, U) measurements.

Strengths

• Data includes multiple geophysical data types (Total Magnetic Intensity, Gamma-ray spectrometry, elevation, Bouguer Gravity).
• Data is sourced from both government and company surveys across Australia and its marine area.
• The collection has been used to create both survey-scale and national-scale grids.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; last metadata update was 2026-05-14.
