Australia's Maritime Jurisdiction Map for Cocos and Christmas Islands

Australia's Maritime Jurisdiction around Cocos (Keeling) Islands and Christmas Island is a constituent map of the 'Australia's Maritime Jurisdiction Map Series'. It depicts Australia's extended continental shelf approved in April 2008, treaties, and various maritime zones over a bathymetric background. The map is published by the Australian Ocean Data Network as an A0-sized PDF.

Use Cases

• Analyze maritime boundary claims based on depicted treaties and maritime zones.
• Study the extent of the continental shelf based on the 2008 Commission-approved limits.
• Reference bathymetric features for oceanographic modeling using the described background grid.
• Produce educational or reference materials on Australia's offshore jurisdiction in the Indian Ocean.

Strengths

• Map is part of a standardized national series of 27 constituent maps.
• Background bathymetry is derived from specific, cited sources: a 2009 9 arc-second grid and a 1997 grid by Smith and Sandwell.
• Depicts legally significant features including a 2008-approved continental shelf and treaty boundaries.

Limitations

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