Australia's Maritime Jurisdiction Map for Central Western Australia

Australia's Maritime Jurisdiction off Central Western Australia is one of 27 maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789). The map depicts Australia's extended continental shelf approved by the Commission on the Limits of the Continental Shelf in April 2008 and various maritime zones. Background imagery combines bathymetric data from 2009 and 1997 sources with land imagery from NASA's Blue Marble.

Use Cases

• Analyze maritime zone boundaries based on the depicted extended continental shelf and maritime zones.
• Study seabed topography for the region based on the combined bathymetric background imagery.
• Reference jurisdictional claims for legal or policy research based on the officially approved continental shelf limits.

Strengths

• Part of a standardized series of 27 constituent maps, suggesting systematic coverage.
• Based on an extended continental shelf approval by an international commission in April 2008.
• Background bathymetry combines data from two specific sources (2009 GA grid and 1997 Smith and Sandwell grid).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing solely on Australian jurisdiction.
