Australia's Northwest Shelf Maritime Jurisdiction Map, 2014

One of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789). The map depicts Australia's continental shelf as proclaimed in the 2012 proclamation under the Seas and Submerged Lands Act 1973. It was updated in June 2014 by Geoscience Australia to conform with the 'Australian Maritime Boundaries 2014' data.

Use Cases

• Visualize maritime boundaries based on the 2012 proclamation and 2014 boundary data.
• Analyze continental shelf extents off the Northwest Shelf based on the geospatial depiction.
• Reference bathymetric and topographic context using the combined 2009 GA grid and 1997 Smith and Sandwell grid.
• Produce A0-sized map outputs for presentation or publication based on the downloadable PDF.

Strengths

• Part of a standardized series of 27 maps providing consistent jurisdictional coverage.
• Updated to conform with the authoritative 'Australian Maritime Boundaries 2014' dataset from Geoscience Australia.
• Background imagery combines bathymetric data from a 2009 9 arc second grid and a 1997 grid by Smith and Sandwell.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
