Australia's Maritime Jurisdiction Map for Cocos and Christmas Islands

Australia's Maritime Jurisdiction around Cocos (Keeling) Islands and Christmas Island is depicted in this map. It is one of 27 constituent maps from the 'Australia's Maritime Jurisdiction Map Series' and shows the extended continental shelf approved in April 2008, treaties, and various maritime zones. The background bathymetric image is derived from a 2009 9 arc second grid and a 1997 grid by Smith and Sandwell.

Use Cases

• Analyze maritime boundary definitions based on depicted continental shelf and treaty zones.
• Study bathymetric patterns based on the combined 2009 and 1997 background grid.
• Compare jurisdictional maps across the 27-map series based on this constituent map.
• Support legal or diplomatic research on Australia's maritime claims based on the treaty and zone information.

Strengths

• Part of a standardized 27-map series (GeoCat 71789), suggesting consistent methodology.
• Integrates bathymetric data from two authoritative sources (GA 2009 grid and Smith and Sandwell 1997 grid).
• Includes multiple legal and geographic features: extended continental shelf, treaties, and maritime zones.

Limitations

• Data format is PDF/HTML; analysis requires conversion or specialized geospatial tools.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
