Description
A set of digital bathymetry, gravity and magnetic grids for southwest Australia (24-46S, 106-140E) produced by the Australian Geological Survey Organisation. The grids were created using all available land, marine and satellite data, processed through a network adjustment on marine ship-track data. The work was done in cooperation with Desmond Fitzgerald & Associates and the Australian Hydrographic Office.
Use Cases
Modeling seafloor topography based on bathymetry grid data
Analyzing crustal structure based on gravity anomaly grids
Mapping magnetic field variations for geological interpretation
Integrating land and marine geophysical data for regional studies
Strengths
Grids cover a defined region (24-46S, 106-140E)
Data integrates multiple sources: land, marine, and satellite
Work involved cooperation with specialized organizations (AGSO, DFA, AHO)
Limitations
Column-level documentation is absent; field semantics must be inferred after download
Row count is unknown, which may limit suitability assessment
