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

Australia's maritime jurisdiction north of approximately 25°S, including areas around the Cocos (Keeling) Islands and west of Christmas Island. The map depicts the extended continental shelf approved in 2008, treaties, and various maritime zones, with background bathymetry from Geoscience Australia and NASA. It is part of a 28-map series and is provided as a 3277mm x 1050mm PDF by the Australian Ocean Data Network.

Use Cases

• Analyze maritime boundary claims and treaties based on the depicted jurisdiction zones.
• Study seabed topography and bathymetry based on the combined Geoscience Australia and Smith & Sandwell grid.
• Visualize the extent of Australia's approved continental shelf north of 25°S for legal or educational purposes.
• Integrate jurisdictional data with other marine spatial planning layers based on the geospatial map format.

Strengths

• Map is part of a standardized 28-map series (GeoCat 71789), suggesting consistent methodology.
• Background bathymetry combines a 2009 9 arc-second grid from Geoscience Australia with a 1997 grid by Smith and Sandwell.
• Includes multiple legal and geographic features: extended continental shelf, treaties, and various maritime zones.
• High-resolution print-ready PDF sized for a 42-inch plotter (3277mm x 1050mm).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
• Data is presented as a static map (PDF/HTML), limiting direct machine-readability and analysis.
