Australia's Maritime Jurisdiction Map for the Northwest Shelf

A geospatial 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 a 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 the depicted jurisdictional zones.
• Study seabed topography based on the combined bathymetric background imagery.
• Reference the legal extent of Australia's continental shelf based on the 2008 Commission approval.
• Integrate jurisdictional data into larger marine spatial planning models based on the map's geospatial features.

Strengths

• Part of a standardized series of 27 constituent maps, suggesting consistent methodology.
• Integrates bathymetric data from two specific sources: a 2009 9 arc-second grid and a 1997 grid by Smith and Sandwell.
• Depicts legally defined features including the continental shelf approved by the Commission on the Limits of the Continental Shelf in April 2008.

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 primary downloadable format is a static A0-sized PDF, which may limit direct machine-readability.
