Australia's Maritime Jurisdiction Map for Southwestern Western Australia

Australia's Maritime Jurisdiction off Southwestern Western Australia is a geospatial map depicting the country's extended continental shelf approved by the Commission on the Limits of the Continental Shelf in April 2008 and various maritime zones. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789). The background bathymetric image combines the 2009 9 arc second grid by Geoscience Australia with a 1997 grid by Smith and Sandwell, and land imagery is derived from NASA's Blue Marble.

Use Cases

• Analyze maritime boundaries and exclusive economic zones based on the depicted legal zones.
• Study seafloor topography and bathymetry based on the combined background grid data.
• Reference legal continental shelf limits for southwestern Western Australia based on the 2008 Commission approval.

Strengths

• Part of a standardized series of 27 maps providing consistent coverage.
• Integrates bathymetric data from two authoritative sources: Geoscience Australia (2009) and Smith and Sandwell (1997).
• Background land imagery is derived from NASA's Blue Marble, a recognized global dataset.

Limitations

• Metadata completeness is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to data_gov_au, focusing on a specific region.
