Australia's Northwest Shelf Maritime Jurisdiction Map with Bathymetry

One of the 27 constituent maps of 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, treaties, and various maritime zones. Background bathymetric imagery is derived from a 2009 9 arc second grid and a 1997 grid by Smith and Sandwell.

Use Cases

• Analyze maritime boundary claims based on the depicted extended continental shelf and treaty lines.
• Study seabed topography for the Northwest Shelf region based on the combined bathymetric background imagery.
• Reference legal and administrative maritime zones for marine spatial planning.
• Integrate jurisdictional boundaries with other oceanographic or economic datasets for the region.

Strengths

• Part of a standardized series of 27 maps providing consistent coverage of Australia's maritime jurisdiction.
• Background bathymetry combines a detailed 2009 9 arc second grid with a 1997 global dataset.
• Depicts legally significant features including the April 2008 approved continental shelf limits and treaty boundaries.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided as a static A0-sized PDF, limiting direct machine-readability and analysis.
• The map is a composite with background data from 1997 and 2009, which may not reflect recent changes.
