Australia's Maritime Jurisdiction Map for Heard and McDonald Islands

Heard Island and McDonald Islands are the focus of this geospatial map depicting Australia's maritime jurisdiction. The map is part of a 27-map series and shows the extended continental shelf approved in 2008, treaties, and maritime zones. It uses a Mercator projection with WGS84 datum and incorporates bathymetric and land imagery from external sources.

Use Cases

• Analyze maritime boundary claims based on the depicted extended continental shelf and zones.
• Study bathymetric features around the islands using the background grid derived from Smith and Sandwell, 1997.
• Reference treaty-defined maritime zones for legal or diplomatic research.
• Integrate map data as a base layer for regional environmental or logistical planning.

Strengths

• Map is part of a standardized 27-constituent map series (GeoCat 71789).
• Depicts legally defined boundaries, including the continental shelf approved by the CLCS in April 2008.
• Background imagery combines bathymetric data from a 1997 grid and land imagery from NASA's Blue Marble.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The underlying bathymetric and land imagery sources are from 1997 and may not reflect current conditions.
