Maritime Jurisdiction Map of Southwestern Western Australia

A geospatial map depicting Australia's maritime jurisdiction off the coast of Southwestern Western Australia. It is one of 27 constituent maps in the national series, created by the Australian Ocean Data Network. The map includes the extended continental shelf approved in 2008 and various maritime zones.

Use Cases

• Analyze the spatial extent of Australia's extended continental shelf boundary for legal or policy research.
• Overlay maritime zone features (e.g., Exclusive Economic Zone) with other oceanographic datasets for jurisdictional analysis.
• Use the bathymetric background layer derived from 9 arc-second and Smith and Sandwell grids for seafloor terrain context.

Strengths

• Part of a standardized national map series comprising 27 constituent maps.
• Integrates authoritative maritime boundaries, including the 2008 Commission-approved continental shelf limits.
• Background bathymetry combines a 2009 9 arc-second grid with a 1997 Smith and Sandwell grid for terrain detail.

Limitations

• Data is provided only as a static A0-sized PDF, limiting machine-readability and direct analysis.
• The underlying source grids for bathymetry are from 1997 and 2009, which may not reflect recent seafloor surveys.
• No attribute table or vector data is provided, preventing querying of specific zone boundaries or metadata.

Provenance

Source

Australian Ocean Data Network, part of the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789).

Time Range

Maritime boundaries reflect the Commission on the Limits of the Continental Shelf approval in April 2008.

Freshness

Last updated record indicates 2026-04-04, but the core jurisdictional data is based on a 2008 approval.

Geography
