Australia's Maritime Jurisdiction Map for Southwestern Western Australia

Australia's Maritime Jurisdiction off Southwestern 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 a 2009 9 arc second bathymetric and topographic grid by Geoscience Australia with a 1997 grid by Smith and Sandwell, and land imagery from NASA's Blue Marble.

Use Cases

• Analyze maritime zone boundaries based on the depicted extended continental shelf and other zones.
• Study seafloor topography (bathymetry) based on the combined background grid data.
• Reference legal maritime claims for southwestern Western Australia based on the official map series.
• Integrate jurisdictional data with other marine spatial planning layers based on the geospatial format.

Strengths

• Part of a standardized series of 27 constituent maps providing consistent coverage.
• Based on authoritative sources including an official 2008 continental shelf approval and grids from Geoscience Australia.
• Includes detailed background bathymetric and topographic imagery derived from specific 2009 and 1997 datasets.

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 primary data format is a static A0-sized PDF, limiting direct machine-readability and analysis.
