One of 27 constituent maps from the Australia's Maritime Jurisdiction Map Series (GeoCat 71789). This A0-sized PDF map depicts Australia's extended continental shelf, treaties, and maritime zones around Tasmania using a Mercator projection. Its background bathymetry combines data from a 2009 9 arc second grid and a 1997 grid by Smith and Sandwell.
Use Cases
- Visualizing maritime boundaries and zones based on the described continental shelf and treaty data.
- Analyzing bathymetric features for marine research based on the combined background grid.
