Australia's Northwest Shelf Maritime Jurisdiction Map with Bathymetry

One map from the 27-constituent 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789). It depicts Australia's extended continental shelf as approved by the Commission on the Limits of the Continental Shelf in April 2008, along with treaties and maritime zones. The background combines bathymetric data from Geoscience Australia (2009) and Smith and Sandwell (1997) with land imagery from NASA's Blue Marble.

Use Cases

• Visualizing maritime boundaries and treaties based on the described jurisdiction zones.
• Analyzing seabed topography for the Northwest Shelf region based on the combined bathymetric background.
• Referencing the legal extent of Australia's continental shelf as approved in 2008 for jurisdictional studies.

Strengths

• Part of a defined 27-map series (GeoCat 71789) providing structured coverage.
• Incorporates authoritative bathymetric data from Geoscience Australia (2009) and Smith and Sandwell (1997).
• Based on a formal continental shelf submission approved by the UN Commission in April 2008.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided as a static A0 PDF, limiting direct machine-readability and analysis.
• Row count is unknown, which may limit suitability assessment for quantitative uses.
