Southwest Australia (24-46S, 106-140E) is covered by digital grids of bathymetry, gravity, and magnetic data. The grids were produced by the Australian Geological Survey Organisation (AGSO) using levelled land, marine, and satellite data, with input from Desmond Fitzgerald & Associates and the Australian Hydrographic Office. The results were obtained by performing a network adjustment on marine ship-track data and combining it with onshore and satellite-derived sources.
Use Cases
- Modeling seafloor topography and geological structures based on the bathymetry grid.
- Analyzing crustal density variations and tectonic features based on the gravity grid.
- Mapping magnetic anomalies and subsurface geology based on the magnetic grid.
- Integrating multi-source geophysical data for regional geological studies.
Strengths
- Covers a large geographic quadrant of southwest Australia (24-46S, 106-140E).
- Integrates data from multiple sources: land, marine ship-tracks, and satellites.
- Data was levelled and adjusted via a network adjustment process.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and data volume are unknown, which may limit suitability assessment.
