Australia's Maritime Jurisdiction Map with Extended Continental Shelf

A 2008-approved map of Australia's extended continental shelf, part of the 27-map 'Australia's Maritime Jurisdiction Map Series'. The background combines bathymetry from Geoscience Australia (2009) and Smith & Sandwell (1997) with land imagery from NASA's Blue Marble. The map is published by the Australian Ocean Data Network and is available as an A0-sized PDF.

Use Cases

• Visualizing maritime boundaries based on the approved continental shelf limits.
• Analyzing bathymetric data derived from the combined 2009 and 1997 grids.
• Referencing jurisdictional extents for Australia and its external territories, including the Australian Antarctic Territory (AAT).

Strengths

• Part of a curated series of 27 constituent maps (GeoCat 71789).
• Incorporates bathymetric data from two authoritative sources: Geoscience Australia (2009) and Smith & Sandwell (1997).
• Based on the extended continental shelf limits approved by the UN Commission in April 2008.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified; the last metadata update is dated 2026-06-23.
