Australia's Maritime Jurisdiction Map Series, 2020 Continental Shelf

A map depicting Australia's continental shelf as proclaimed in the Seas and Submerged Lands (Limits of Continental Shelf) Proclamation 2012. The background bathymetric image is derived from a 2009 9 arc second grid by Geoscience Australia and a 1997 grid by Smith and Sandwell. It is one of 27 constituent maps in the Australia's Maritime Jurisdiction Map Series, updated in April 2021.

Use Cases

• Visualize maritime legal boundaries based on the proclaimed continental shelf limits.
• Analyze bathymetric features based on the combined background grid data.
• Study the spatial extent of Australia's maritime jurisdiction around the continent.
• Integrate jurisdictional maps as a base layer for marine spatial planning.

Strengths

• Map is part of a standardized series of 27 constituent maps.
• Background bathymetry combines data from two specific sources: Geoscience Australia (2009) and Smith and Sandwell (1997).
• Legal boundaries are defined by a specific proclamation (2012) and act (1973).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
