Australia's Northwest Shelf Maritime Jurisdiction Map, 2014

Geoscience Australia's map shows Australia's maritime jurisdiction off the Northwest Shelf, updated in June 2014. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series'. The map depicts the continental shelf as proclaimed in the 2012 proclamation and uses bathymetric and topographic background imagery from multiple sources.

Use Cases

• Analyze maritime boundaries based on the proclaimed continental shelf limits.
• Visualize seafloor topography based on the combined bathymetric grid background.
• Reference legal and administrative maritime zones for the Northwest Shelf region.

Strengths

• Part of a defined map series containing 27 constituent maps.
• Background combines bathymetric data from a 2009 9 arc-second grid and a 1997 grid by Smith and Sandwell.
• Based on a specific legal proclamation (Seas and Submerged Lands Act 1973).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
