Australia's Maritime Jurisdiction Map for the Northwest Shelf

Geoscience Australia Data provides a map depicting Australia's maritime jurisdiction off the Northwest Shelf. It is one of 27 maps in the 'Australia's Maritime Jurisdiction Map Series' and shows the extended continental shelf approved in April 2008, treaties, and various maritime zones. The background combines bathymetric data from Geoscience Australia's 2009 grid and a 1997 grid by Smith and Sandwell, with land imagery from NASA's Blue Marble.

Use Cases

• Analyze maritime boundaries and treaties based on depicted jurisdictional zones.
• Study bathymetric features of the Northwest Shelf based on the combined background grid.
• Reference the approved 2008 continental shelf limits for legal or research purposes.
• Integrate the map as a base layer for regional marine spatial planning.

Strengths

• Part of a standardized series of 27 constituent maps.
• Background bathymetry combines data from Geoscience Australia's 2009 9 arc-second grid and a 1997 grid by Smith and Sandwell.
• Land imagery is sourced from NASA's Blue Marble.
• Depicts legally significant features like the April 2008 approved continental shelf limits.

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 is provided as a static A0-sized PDF, limiting direct computational analysis.
