A gravity anomaly image derived from approximately 1.8 million gravity observations in the Australian National Gravity Database and a 2013 Riverina survey. The Commonwealth, State and Territory Governments, the mining industry, universities, and research organizations collected the data from the 1940s onward. Terrain corrections using offshore bathymetry and onshore topography were applied to produce the complete Bouguer anomalies.
Use Cases
- Identify subsurface geological structures based on complete Bouguer anomaly patterns.
- Support mineral exploration targeting based on gravity anomaly variations.
- Integrate with other geophysical datasets for regional geological modeling.
- Visualize terrain-corrected gravity data for educational or research purposes.
Strengths
- Derived from approximately 1.8 million gravity observations, including 1,371,998 stations from the ANGD.
- Incorporates 19,558 stations from a dedicated 2013 Riverina survey.
- Terrain corrections applied using both offshore bathymetry and onshore topography data.
- Data sourced from government, industry, and academic institutions over a long period (1940s onward).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic or temporal bias inherent to data_gov_au.
