Maritime Jurisdiction Map of Central Western Australia

Australia's Maritime Jurisdiction off Central Western Australia is a constituent map of the Australia's Maritime Jurisdiction Map Series. It depicts the extended continental shelf approved in 2008 and various maritime zones, created by the Australian Ocean Data Network. The map is available as an A0 sized PDF.

Use Cases

• Analyze the spatial extent of Australia's extended continental shelf boundary for legal or policy research.
• Use the bathymetric background layer derived from 2009 and 1997 grids for seafloor topography studies.
• Overlay maritime zone boundaries (e.g., Exclusive Economic Zone) with other marine spatial data for planning.
• Reference the Commission on the Limits of the Continental Shelf 2008 approval for historical jurisdictional analysis.

Strengths

• Part of a standardized series of 27 constituent maps providing national coverage.
• Integrates bathymetric data from two specific sources: GA's 2009 9 arc second grid and Smith and Sandwell, 1997.

Limitations

• Data is static, representing a jurisdictional snapshot from April 2008 with no stated updates.
• Primary format is a PDF map, limiting direct machine-readability and analysis of underlying vector data.
• Sample size and specific row/column counts for any underlying data are unknown.
