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

One of 27 maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789). It 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. The map is a 2800mm x 1050mm PDF, with background bathymetry derived from Geoscience Australia's 2009 grid and a 1997 grid by Smith and Sandwell.

Use Cases

• Analyze maritime jurisdiction boundaries based on the depicted treaties and maritime zones.
• Study continental shelf extents based on the 2008 Commission-approved limits.
• Incorporate bathymetric background imagery for oceanographic or geological modeling.

Strengths

• Part of a standardized series of 27 constituent maps, suggesting consistent methodology.
• Background bathymetry combines data from two authoritative sources: Geoscience Australia (2009) and Smith & Sandwell (1997).
• Map dimensions (2800mm x 1050mm) are specified for a 42" plotter, indicating high-resolution output.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing only on Northern Australia and Christmas Island.
