Australia's Maritime Jurisdiction Maps for Cocos and Christmas Islands

One of 27 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 maritime zones. Background bathymetry combines a 2009 9 arc-second grid by Geoscience Australia with a 1997 grid by Smith and Sandwell.

Use Cases

• Analyze maritime boundary claims based on depicted continental shelf limits and treaties.
• Study ocean floor topography using the combined bathymetric background image.
• Reference jurisdictional zones for legal or environmental planning around the Cocos (Keeling) and Christmas Islands.

Strengths

• Part of a standardized series of 27 constituent maps providing consistent coverage.
• Integrates bathymetric data from two authoritative sources: Geoscience Australia (2009) and Smith and Sandwell (1997).
• Based on a formal continental shelf submission approved by an international commission in 2008.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
