Australia's Maritime Jurisdiction Map for Cocos and Christmas Islands

A geospatial map depicting Australia's maritime jurisdiction 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). The map shows the extended continental shelf approved in April 2008, various maritime zones, and uses a background bathymetric image derived from 2009 and 1997 grids.

Use Cases

• Visualizing maritime boundaries and treaties based on the described jurisdictional zones.
• Analyzing bathymetric data for oceanographic research based on the combined background grid.
• Referencing the legal extent of Australia's continental shelf for policy or educational purposes.

Strengths

• Part of a standardized series of 27 maps, suggesting consistent methodology.
• Includes bathymetric data derived from a combination of the 2009 9 arc second grid and a 1997 grid by Smith and Sandwell.
• Based on the extended continental shelf limits approved by the UN Commission in April 2008.

Limitations

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