Australia's Maritime Jurisdiction Map for Heard and McDonald Islands

A geospatial map depicting Australia's maritime jurisdiction around Heard Island and McDonald Islands, including a portion of the Australian Antarctic Territory. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789). The map shows the extended continental shelf approved by the Commission on the Limits of the Continental Shelf in April 2008, treaties, and various maritime zones.

Use Cases

• Analyze maritime boundaries and exclusive economic zones based on the depicted jurisdiction zones.
• Study the extent of Australia's continental shelf claim based on the 2008 CLCS approval.
• Use the bathymetric background for oceanographic or geological research in the Southern Ocean region.
• Reference treaty-defined maritime zones for legal or diplomatic analysis.

Strengths

• Part of a standardized series of 27 maps providing consistent jurisdictional mapping.
• Based on authoritative sources including a 2008 CLCS decision and official treaties.
• Includes detailed background bathymetry from Smith and Sandwell (1997) and NASA Blue Marble land imagery.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; the underlying legal and bathymetric data may be outdated.
