Maritime Jurisdiction Map of Heard and McDonald Islands with Bathymetry

Geoscience Australia provides a map depicting Australia's maritime jurisdiction around Heard Island and McDonald Islands. The map shows the extended continental shelf approved in 2008, various maritime zones, and treaties, overlaid on bathymetric and land imagery. It is one of 27 maps in the 'Australia's Maritime Jurisdiction Map Series' and is available as an A0-sized PDF.

Use Cases

• Analyze maritime boundary claims and treaties based on depicted jurisdictional zones.
• Study the extent of the continental shelf based on the 2008 Commission approval data.
• Use the bathymetric background for regional seafloor topography analysis.
• Reference the map for legal or diplomatic discussions concerning the Australian Antarctic Territory.

Strengths

• Part of a standardized series of 27 constituent maps providing consistent coverage.
• Based on authoritative sources including a 1997 bathymetric grid and NASA Blue Marble imagery.
• Includes legally significant boundaries such as the 2008-approved continental shelf limits.

Limitations

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