Australia's Maritime Jurisdiction Map with Extended Continental Shelf

Geoscience Australia Data provides a map depicting Australia's maritime jurisdiction and extended continental shelf approved in April 2008. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789). The background combines bathymetric data from a 2009 9 arc-second grid and a 1997 grid by Smith and Sandwell, with land imagery from NASA's Blue Marble.

Use Cases

• Visualizing national maritime boundaries based on the described jurisdiction map.
• Analyzing the extent of the continental shelf based on the 2008 Commission approval.
• Studying bathymetric features using the combined background grid data mentioned in the description.

Strengths

• Part of a defined series of 27 constituent maps (GeoCat 71789).
• Based on an extended continental shelf approval by an international commission in April 2008.
• Background bathymetry combines data from a 2009 9 arc-second grid and a 1997 source.

Limitations

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