Australia's Maritime Jurisdiction Maps for Cocos and Christmas Islands

A geospatial map depicting Australia's maritime jurisdiction zones around the Cocos (Keeling) Islands and Christmas Island. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789), published by Geoscience Australia. The map shows the extended continental shelf approved in April 2008, treaties, and various maritime zones over a bathymetric background.

Use Cases

• Analyze maritime boundary claims and treaties based on the depicted jurisdictional zones.
• Study the extent of Australia's continental shelf based on the 2008 Commission approval.
• Incorporate bathymetric data for oceanographic or geological modeling based on the described background grid.
• Reference jurisdictional limits for marine spatial planning and resource management around the islands.

Strengths

• Part of a standardized series of 27 maps, providing consistent context.
• Based on a defined legal framework, including the 2008 Commission on the Limits of the Continental Shelf approval.
• Background bathymetry is derived from specific, cited sources (GA 2009 grid and Smith and Sandwell, 1997).

Limitations

• Data is provided only in PDF and HTML formats, limiting direct machine-readability and analysis.
• Column-level documentation and sample data are unavailable, requiring manual inspection after download.
• The description does not specify the map's projection or detailed spatial accuracy metrics.
