Australia's Maritime Jurisdiction Map with Extended Continental Shelf

Geoscience Australia Data provides a map depicting Australia's maritime jurisdiction around the continent. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' and shows the extended continental shelf approved by the Commission on the Limits of the Continental Shelf in April 2008. The background combines a 2009 9 arc-second bathymetric and topographic grid with a 1997 grid by Smith and Sandwell, and land imagery from NASA's Blue Marble.

Use Cases

• Analyze maritime boundary extents based on the depicted jurisdiction and continental shelf.
• Study bathymetric features using the combined background grid data mentioned in the description.
• Reference jurisdictional claims for legal or policy research based on the 2008 CLCS approval.
• Create base maps for marine spatial planning using the integrated bathymetric and topographic background.

Strengths

• Part of a defined series of 27 constituent maritime jurisdiction maps.
• Based on a specific legal decision from the Commission on the Limits of the Continental Shelf in April 2008.
• Background combines multiple authoritative data sources, including a 2009 9 arc-second grid and a 1997 grid.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
• The map excludes Cocos Island, subantarctic territories, and the Australian Antarctic Territory.
