Australia's Maritime Jurisdiction Map for Heard and McDonald Islands

One of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789). The map depicts Australia's extended continental shelf approved by the Commission on the Limits of the Continental Shelf in April 2008, along with treaties and various maritime zones. It was created by Geoscience Australia using a Mercator projection and includes background bathymetry from Smith and Sandwell (1997) and land imagery from NASA's Blue Marble.

Use Cases

• Analyze maritime boundaries and territorial claims based on depicted maritime zones and treaties.
• Study the extent of Australia's continental shelf based on the approved 2008 submission.
• Use bathymetric data for oceanographic or geological research based on the Smith and Sandwell grid background.

Strengths

• Part of a standardized series of 27 maps, suggesting consistent methodology.
• Incorporates authoritative data sources including a 1997 global bathymetry grid and NASA imagery.
• Based on a formal submission to the Commission on the Limits of the Continental Shelf.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the source platform and the 2008 submission date.
