Australia's Maritime Jurisdiction Map for Cocos and Christmas Islands

One of the 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 published by the Australian Ocean Data Network and was last updated on 2026-06 04.

Use Cases

• Analyze maritime zone boundaries based on treaties and continental shelf limits.
• Study seabed topography based on the combined 2009 9 arc second and 1997 Smith and Sandwell bathymetric grids.
• Reference jurisdictional claims for legal or diplomatic research based on the depicted maritime zones.

Strengths

• Part of a standardized series of 27 maps, suggesting consistent methodology.
• Incorporates bathymetric data from two authoritative sources: Geoscience Australia (2009) and Smith and Sandwell (1997).
• Based on a formal international submission approved by the Commission on the Limits of the Continental Shelf in April 2008.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided as a static A0-sized PDF, limiting direct computational analysis.
• Row count is unknown, which may limit suitability assessment for quantitative modeling.
