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 from the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789). The map depicts Australia's extended continental shelf approved in April 2008, treaties, and various maritime zones over a bathymetric background. It is an A0 sized PDF downloadable via the Australian Ocean Data Network.

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 regional oceanographic modeling based on the described background grid.

Strengths

• Part of a standardized national map series (GeoCat 71789), suggesting consistent cartographic methods.
• Includes multiple jurisdictional layers: extended continental shelf, treaties, and various maritime zones.
• Background bathymetry is derived from specific, cited sources (GA 2009 grid and Smith and Sandwell, 1997).

Limitations

• Description metadata is limited; actual data quality and coordinate precision require manual inspection after download.
• Column-level documentation is absent; field semantics and underlying vector/raster data must be inferred after download.
