Maritime Jurisdiction Map of Tasmania and Macquarie Island

One map from the 27-constituent 'Australia's Maritime Jurisdiction Map Series'. It depicts Australia's extended continental shelf as approved in April 2008, along with treaty boundaries and various maritime zones around Tasmania and Macquarie Island. The map is produced by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Analyze the spatial extent of Australia's approved continental shelf boundaries around Tasmania for legal research.
• Use the depicted maritime zones (e.g., Exclusive Economic Zone) for marine spatial planning and resource allocation studies.
• Integrate the background bathymetric data derived from the 2009 9 arc-second grid for oceanographic modeling in the region.
• Reference treaty boundaries and jurisdictional lines for creating navigational or regulatory charts.

Strengths

• Part of a standardized series of 27 constituent maps, ensuring consistent national coverage.
• Incorporates authoritative bathymetric background from the 2009 9 arc-second grid and Smith and Sandwell (1997) data.

Limitations

• Data is static and based on a continental shelf submission approved in 2008, which may not reflect recent treaties or claims.
• Primary format is a PDF map, limiting direct machine-readability and analysis of underlying vector boundaries.
• No underlying tabular data or feature attributes (like coordinates) are explicitly provided for the depicted zones.
