Australia's Maritime Jurisdiction Map for Central Western Australia

A geospatial map depicting Australia's maritime jurisdiction off Central Western Australia. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789) from Geoscience Australia. The map shows the extended continental shelf approved in April 2008 and various maritime zones, with a background bathymetric image derived from 2009 and 1997 sources.

Use Cases

• Visualizing maritime boundaries and zones based on the described jurisdictional data.
• Analyzing continental shelf extents based on the 2008 Commission approval.
• Using bathymetric background imagery for marine spatial planning.
• Referencing jurisdictional limits for legal or environmental assessments.

Strengths

• Part of a defined series of 27 constituent maps with a known catalog number (GeoCat 71789).
• Based on authoritative sources including a 2009 bathymetric grid and a 1997 grid by Smith and Sandwell.
• Depicts legally recognized boundaries from the Commission on the Limits of the Continental Shelf (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 computational analysis.
• Row count is unknown, which may limit suitability assessment for quantitative uses.
