Australia's Maritime Jurisdiction Map for Heard and McDonald Islands

A geospatial map depicting Australia's maritime jurisdiction around Heard Island and McDonald Islands. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789) and shows the extended continental shelf approved in April 2008, treaties, and maritime zones. The map uses a Lambert Conformal Conic Projection with background imagery from Smith and Sandwell (1997) bathymetry and NASA's Blue Marble.

Use Cases

• Analyze maritime zone boundaries based on the depicted treaties and jurisdictions.
• Study the extent of Australia's continental shelf claim based on the 2008 Commission approval.
• Use the bathymetric background for oceanographic or geological research in the Southern Ocean.
• Reference jurisdictional limits for environmental or resource management planning in the region.

Strengths

• Part of a standardized series of 27 maps providing consistent jurisdictional coverage.
• Includes the legally defined extended continental shelf boundary approved by the Commission on the Limits of the Continental Shelf in April 2008.
• Background layers incorporate established data sources: Smith and Sandwell (1997) bathymetry and NASA's Blue Marble imagery.

Limitations

• Data is provided as a static A0-sized PDF, limiting direct geospatial analysis without conversion.
• Column-level documentation is absent; field semantics must be inferred after download.
