Maritime Jurisdiction Map for Cocos and Christmas Islands

One map from a 27-map series defines Australia's maritime boundaries around the Cocos (Keeling) Islands and Christmas Island. The Australian Ocean Data Network produced this A0-sized PDF, incorporating bathymetric data from 2009 and 1997 sources. It depicts zones like the extended continental shelf approved by the UN Commission in April 2008.

Use Cases

• Analyze the spatial extent of Australia's approved extended continental shelf boundary around the islands.
• Compare maritime zone boundaries (e.g., exclusive economic zone) depicted on this map with other regional claims.
• Use the integrated bathymetric background layer for correlating jurisdiction lines with underwater topography.

Strengths

• Part of a standardized 27-map national series (GeoCat 71789) ensuring consistent cartographic treatment.
• Integrates bathymetric data from two authoritative sources: a 2009 9 arc-second grid and the 1997 Smith and Sandwell grid.

Limitations

• Data is static and based on a treaty situation and continental shelf approval from 2008, which may not reflect subsequent changes.
• The primary deliverable is a PDF map, requiring extraction for quantitative geospatial analysis.
