Australian Geophysical Survey Extents and Metadata from Geoscience Australia

Geoscience Australia and its predecessor agencies, along with State and Territory geological survey agencies, conduct and manage the surveys described. This web service provides geographical extents and descriptive metadata for geophysical datasets, which include gravity, magnetic, radiometric, electromagnetic, and elevation data. The service was last updated on 2026-06-05.

Use Cases

• Map subsurface geological structures based on gravity and magnetic data.
• Conduct mineral exploration targeting based on radiometric and electromagnetic survey data.
• Create regional elevation models using elevation data collected during geophysical surveys.
• Perform metadata discovery for historical and contemporary geophysical surveys across Australia.

Strengths

• Aggregates data from multiple authoritative sources, including Geoscience Australia and all State and Territory geological survey agencies.
• Covers multiple geophysical data types: gravity, magnetic, radiometric, electromagnetic, and elevation.
• Last updated on 2026-06-05, indicating recent maintenance.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic or temporal bias inherent to the source surveys.
