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 map background combines a 2009 9 arc second bathymetric grid from Geoscience Australia with a 1997 grid by Smith and Sandwell, overlaid on NASA Blue Marble land imagery. It is an A0-sized PDF available for download.

Use Cases

• Analyze maritime boundary definitions based on the depicted continental shelf and maritime zones.
• Study bathymetric features off the southwestern Australian coast based on the combined background grid.
• Reference jurisdictional limits for legal or environmental planning based on the official map series.
• Integrate as a base layer for regional marine spatial planning based on the geospatial imagery.

Strengths

• Part of a standardized series of 27 official maritime jurisdiction maps.
• Background bathymetry derived from a specific 2009 9 arc second grid and a 1997 source.
• Based on the extended continental shelf formally approved by the CLCS in April 2008.

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.
