Australia's Maritime Jurisdiction Map for Heard and McDonald Islands

Geoscience Australia Data provides a map depicting Australia's maritime jurisdiction around Heard Island and McDonald Islands. The map shows the extended continental shelf approved in 2008, treaties, and various maritime zones, with background bathymetry from 1997 and land imagery from NASA. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' and is available as an A0-sized PDF.

Use Cases

• Analyze maritime boundary definitions based on the depicted treaties and maritime zones.
• Study continental shelf extents based on the 2008 Commission-approved limits.
• Incorporate bathymetric background for oceanographic or geological modeling based on the Smith and Sandwell 1997 grid.
• Use as a base map for regional environmental or policy studies based on the geospatial jurisdiction layers.

Strengths

• Part of a standardized series of 27 maps providing consistent jurisdictional coverage.
• Based on authoritative sources including a 2008 Commission decision and specific bathymetric/imagery datasets.
• Uses a defined Lambert Conformal Conic Projection with WGS84 Datum for geospatial accuracy.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided as a static PDF/A0 map, limiting direct machine-readability and analysis.
