Australia's Maritime Jurisdiction Map for the Northwest Shelf

One of 27 constituent maps in the Australia's Maritime Jurisdiction Map Series, depicting maritime zones and the extended continental shelf approved in April 2008. The map background combines bathymetric data from a 2009 9 arc-second grid and a 1997 grid by Smith and Sandwell, with land imagery from NASA's Blue Marble. It is an A0-sized PDF published by Geoscience Australia.

Use Cases

• Visualize maritime boundaries and treaties based on the depicted maritime zones.
• Analyze seabed topography for the Northwest Shelf region based on the combined bathymetric background.
• Reference legal and administrative maritime limits based on the approved 2008 continental shelf extension.

Strengths

• Part of a standardized series of 27 maps for consistent maritime jurisdiction reference.
• Background bathymetry is derived from a specified 2009 9 arc-second grid and a 1997 source.
• Based on the extended continental shelf formally approved by the UN Commission 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 for quantitative analysis.
• The primary downloadable format is a static PDF, which may limit direct data extraction.
