The Complete Bouguer Gravity Anomaly Grid of Onshore Australia 2016 is derived from approximately 1.8 million gravity observations, including 1,371,998 stations from the Australian National Gravity Database and 19,558 from the 2013 Riverina survey. The grid was produced by the Australian Ocean Data Network using data acquired by government, industry, and research entities from the 1940s onward. Terrain corrections were applied using offshore bathymetry and onshore topography data.
Use Cases
- Model subsurface geological structures based on complete Bouguer anomaly values.
- Analyze regional gravity variations for mineral exploration based on the onshore continental grid.
- Integrate terrain-corrected gravity data with other geospatial datasets for resource assessment.
- Train ML models to predict geological features from gravity anomaly patterns.
Strengths
- Derived from a large base of approximately 1.8 million gravity observations.
- Incorporates data from multiple sources including government, industry, and academia spanning decades.
- Terrain corrections were applied using both offshore bathymetry and onshore topography.
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 temporal bias inherent to data_gov_au, as it includes historical records from the 1940s.
