Australia's Maritime Jurisdiction Map with Bathymetry, 2020

Geoscience Australia's map depicts Australia's maritime jurisdiction and continental shelf as proclaimed in 2012. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' and was updated in April 2021. The background combines bathymetric data from 2009 and 1997 with land imagery from NASA's Blue Marble.

Use Cases

• Visualizing Australia's legal maritime jurisdiction based on the proclaimed continental shelf.
• Analyzing bathymetric data for marine research based on the combined 2009 and 1997 grids.
• Creating reference maps for maritime regulation based on the official Geoscience Australia series.

Strengths

• Part of a standardized series of 27 constituent maps.
• Based on official proclamations under the Seas and Submerged Lands Act 1973.
• Background imagery combines multiple authoritative sources (GA, Smith and Sandwell, NASA).

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.
