Australia's Maritime Jurisdiction Map for Southwestern Western Australia

One of 27 maps in the Australia's Maritime Jurisdiction Map Series, depicting the extended continental shelf approved in April 2008 and various maritime zones. The background combines bathymetric data from Geoscience Australia's 2009 grid and a 1997 grid by Smith and Sandwell, with land imagery from NASA's Blue Marble. The map is available as an A0-sized PDF downloadable from the web.

Use Cases

• Visualizing maritime boundaries and the extended continental shelf based on the 2008 Commission approval.
• Analyzing bathymetric features off Southwestern Western Australia based on the combined 2009 and 1997 grids.
• Creating base maps for marine spatial planning using the integrated bathymetric and topographic background.
• Referencing official maritime zones for legal or jurisdictional research.

Strengths

• Part of a standardized series of 27 constituent maps, providing a systematic view.
• Integrates authoritative bathymetric data from Geoscience Australia's 2009 9 arc-second grid.
• Background land imagery is derived from NASA's Blue Marble, a recognized global composite.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
• The underlying bathymetric data includes a grid from 1997, which may be outdated for some applications.
