Australia's Maritime Jurisdiction Map for Heard and McDonald Islands

Australia's Maritime Jurisdiction around Heard Island and McDonald Islands is a constituent map of the national Maritime Jurisdiction Map Series. It depicts Australia's extended continental shelf approved in April 2008, treaties, and various maritime zones. The background bathymetric image is derived from a grid by Smith and Sandwell, 1997, and land imagery from NASA's Blue Marble.

Use Cases

• Analyze maritime boundary definitions based on the depicted extended continental shelf and treaties.
• Study bathymetric features around the islands based on the Smith and Sandwell, 1997 grid.
• Reference jurisdictional claims in the Antarctic region based on the inclusion of a portion of the Australian Antarctic Territory.
• Create derivative maps for legal or educational purposes based on the Mercator projection and WGS84 datum.

Strengths

• Part of a standardized national map series comprising 27 constituent maps.
• Based on an authoritative continental shelf approval by the Commission on the Limits of the Continental Shelf in April 2008.
• Uses specific, documented background data sources: bathymetry from Smith and Sandwell, 1997 and land imagery from NASA's Blue Marble.

Limitations

• Metadata completeness is limited; column-level documentation is absent.
• The data is provided only as an A0 sized PDF and HTML, limiting direct data extraction.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
