Australia's Maritime Jurisdiction Map, 2020 Boundaries and Bathymetry

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, updated in April 2021 to conform with Geoscience Australia's 'Australian Maritime Boundaries 2020' data. Background imagery combines bathymetric data from Geoscience Australia (2009) and Smith and Sandwell (1997) with land imagery from NASA's Blue Marble.

Use Cases

• Visualizing maritime jurisdictional claims based on the proclaimed 2012 continental shelf limits.
• Analyzing oceanographic context using the combined bathymetric and topographic background grid.
• Referencing official maritime boundaries for legal or regulatory compliance purposes.
• Integrating jurisdictional layers with other marine spatial planning datasets.

Strengths

• Part of a defined series of 27 constituent maps, providing a structured collection.
• Based on authoritative legal proclamations and official 'Australian Maritime Boundaries 2020' data from Geoscience Australia.
• Background combines multiple data sources, including a 2009 9 arc-second grid and NASA's Blue Marble imagery.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Excludes Cocos Island, subantarctic territories, and the Australian Antarctic Territory, limiting geographic completeness.
• Column-level documentation is absent; field semantics must be inferred after download.
