Description
Geoscience Australia Data produced digital bathymetry, gravity and magnetic grids for southwest Australia. The grids cover the region from 24 to 46 degrees South and 106 to 140 degrees East, integrating land, marine, and satellite data. The work involved cooperation with Desmond Fitzgerald & Associates and significant bathymetric data input from the Australian Hydrographic Office.
Use Cases
Modeling seafloor topography based on the described bathymetry grids
Analyzing crustal density variations based on the described gravity data
Mapping magnetic anomalies for geological interpretation based on the described magnetic grids
Integrating multi-source geophysical data for regional studies based on the described network adjustment of ship-track, onshore, and satellite data
Strengths
Grids cover a large geographic area spanning 24 to 46 degrees South and 106 to 140 degrees East
Data integrates multiple sources including land, marine, and satellite-derived inputs
Work was done in cooperation with specialized external consultants (Desmond Fitzgerald & Associates) and the Australian Hydrographic Office
