Australia's Maritime Jurisdiction Map for Heard and McDonald Islands

Heard Island and McDonald Islands maritime jurisdiction map shows Australia's extended continental shelf and various maritime zones. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789), created by Geoscience Australia. The map uses a Mercator projection with a WGS84 datum and incorporates bathymetric and land imagery from external sources.

Use Cases

• Visualizing maritime boundaries and jurisdiction based on the described continental shelf and treaty zones.
• Analyzing bathymetric context for the region based on the Smith and Sandwell 1997 grid mentioned.
• Referencing official territorial claims for legal or educational purposes based on the Commission on the Limits of the Continental Shelf 2008 approval.

Strengths

• Part of a standardized series of 27 maps providing consistent jurisdictional coverage.
• Based on an extended continental shelf approval by an international commission in April 2008.
• Integrates specific bathymetric (Smith and Sandwell, 1997) and land imagery (NASA Blue Marble) sources.

Limitations

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