Australia's Maritime Jurisdiction Map for Heard and McDonald Islands

One of the 27 constituent maps of the Australia's Maritime Jurisdiction Map Series (GeoCat 71789). This map depicts Australia's extended continental shelf approved by the Commission on the Limits of the Continental Shelf in April 2008, treaties, and various maritime zones around Heard Island and McDonald Islands. The background bathymetric image is derived from a grid by Smith and Sandwell, 1997, and land imagery from Blue Marble, NASA's Earth Observatory.

Use Cases

• Analyze maritime zone boundaries based on the depiction of treaties and various zones
• Study bathymetric features based on the background image derived from Smith and Sandwell, 1997
• Visualize Australia's extended continental shelf claims approved in April 2008
• Compare jurisdictional maps within the 27-map series for the Australian Antarctic Territory

Strengths

• Part of a standardized 27-map series (GeoCat 71789) providing consistent coverage
• Based on authoritative sources: continental shelf approval from April 2008 and bathymetry from Smith and Sandwell, 1997
• Includes multiple jurisdictional elements: treaties, maritime zones, and the extended continental shelf

Limitations

• Metadata completeness is limited; column-level documentation is absent
• Data is provided as a static PDF/A0 map, limiting direct analysis of underlying vector data
