Individual airborne survey lines of geophysical data sourced from publicly available government- and company-acquired surveys in Australia and its surrounding marine area. The collection includes Total Magnetic Intensity, Gamma-ray spectrometry (radiometrics - K, Th, U), elevation, and ground-based Bouguer Gravity. These datasets have been used to create both survey-scale and national grids.
Use Cases
- Mineral exploration based on gamma-ray spectrometry (K, Th, U) data
- Geological structure mapping based on Total Magnetic Intensity data
- Basin analysis and tectonic studies based on Bouguer Gravity data
- Creating national-scale geophysical grids based on aggregated survey lines
Strengths
- Data includes multiple geophysical types: Total Magnetic Intensity, Gamma-ray spectrometry, elevation, and Bouguer Gravity
- Sourced from publicly available government- and company-acquired surveys across Australia and its marine area
- Hosted at the National Computational Infrastructure (NCI), suggesting institutional support
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Description metadata is limited; actual data quality requires manual inspection after download
