Australia's Maritime Jurisdiction Map for Northern Australia and Christmas Island

One of 27 constituent 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, along with treaties and various maritime zones. It is a 2800mm x 1050mm sized PDF downloadable from the web, with background imagery derived from Geoscience Australia and NASA's Blue Marble.

Use Cases

• Analyze maritime zone boundaries based on the depicted extended continental shelf and treaties.
• Study bathymetric features off northern Australia using the derived background imagery.
• Reference jurisdictional limits for legal or environmental planning in the region.

Strengths

• Part of a standardized series of 27 maps, suggesting consistent methodology.
• Background bathymetry combines data from Geoscience Australia (2009) and Smith & Sandwell (1997).
• Specific physical dimensions (2800mm x 1050mm) are provided for plotting.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided as a static PDF/HTML map, limiting direct machine-readability and analysis.
• Freshness should be verified; the underlying treaty and continental shelf data may be updated.
