Australia's Maritime Jurisdiction Map North of 25°S, Including Extended Continental Shelf

One of 28 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789). The map depicts Australia's extended continental shelf approved in April 2008, treaties, and various maritime zones north of approximately 25°S, including areas around Cocos (Keeling) Islands and west of Christmas Island. Background imagery combines bathymetry from Geoscience Australia (2009) and Smith & Sandwell (1997) with NASA's Blue Marble land imagery.

Use Cases

• Analyze maritime boundaries and jurisdictional claims based on the depicted treaties and zones.
• Study the extent of Australia's continental shelf based on the 2008 Commission approval.
• Use bathymetric and land imagery for regional geographic reference and analysis.
• Reference maritime zones for legal or environmental planning in northern Australian waters.

Strengths

• Part of a standardized series of 28 maps providing systematic coverage.
• Integrates authoritative data sources including a 2009 bathymetric grid and a 1997 grid by Smith and Sandwell.
• Based on the officially approved extended continental shelf limits from April 2008.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified; the last metadata update is dated 2026-06-27.
• The primary downloadable file is a large-format PDF (3277mm x 1050mm) which may not be machine-readable without processing.
