Australia's Maritime Jurisdiction Map Series, 2020 Edition

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, 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 NASA's Blue Marble land imagery.

Use Cases

• Visualizing maritime boundaries for legal and policy analysis based on the proclaimed continental shelf limits.
• Integrating bathymetric context for marine spatial planning based on the combined background grid data.
• Referencing jurisdictional extents for environmental or resource management based on the 2020 maritime boundaries data.

Strengths

• Part of a defined series of 27 constituent maps (GeoCat 71789).
• Updated in April 2021 to align with authoritative 'Australian Maritime Boundaries 2020' data from Geoscience Australia.
• Background combines multiple authoritative sources: Geoscience Australia's 2009 bathymetric grid and Smith and Sandwell's 1997 grid.

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.
• Data may reflect geographic bias inherent to data_gov_au, excluding Cocos Island and subantarctic territories.
