Australia's Maritime Jurisdiction North of 25°S, Including Extended Continental Shelf

One of 28 constituent 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, treaties, and various maritime zones north of approximately 25°S. Background imagery combines bathymetry from Geoscience Australia and NASA's Blue Marble.

Use Cases

• Analyze maritime boundary definitions based on treaties and continental shelf approvals mentioned in the description.
• Visualize jurisdictional areas north of 25°S, including around Cocos (Keeling) Islands and west of Christmas Island.
• Combine bathymetric and topographic data for regional oceanographic studies based on the described background imagery sources.

Strengths

• Part of a standardized series of 28 maps, suggesting consistent methodology.
• Background imagery derived from authoritative sources: Geoscience Australia's 2009 bathymetry grid and NASA's Blue Marble.
• Based on official continental shelf approvals and treaties dated April 2008.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided as a static PDF map sized for a 42-inch plotter (3277mm x 1050mm), limiting direct data extraction.
