Australia's Maritime Jurisdiction Map for Heard and McDonald Islands

The Australian Ocean Data Network provides 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' and shows the extended continental shelf approved in 2008, treaties, and various maritime zones. The map uses a Lambert Conformal Conic Projection with a background derived from bathymetric and land imagery sources.

Use Cases

• Analyze maritime boundary definitions based on the depicted continental shelf and treaty zones.
• Study bathymetric features around sub-Antarctic islands using the derived background grid.
• Reference jurisdictional claims for legal or environmental assessments based on the approved continental shelf limits.
• Integrate as a base layer for regional mapping projects based on its standardized projection and datum.

Strengths

• Map is part of a standardized national series of 27 constituent maps.
• Based on the extended continental shelf formally approved by the Commission on the Limits of the Continental Shelf in April 2008.
• Uses specific, documented cartographic parameters: Lambert Conformal Conic Projection, WGS84 Datum, Central Meridian 76°E.

Limitations

• Data is provided only as a static PDF/A0 image, limiting direct geospatial analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
• Background bathymetry is derived from a 1997 source, which may not reflect recent surveys.
