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

A 3277mm x 1050mm map depicting Australia's maritime jurisdiction north of approximately 25°S, including areas around Cocos (Keeling) Islands, west of Christmas Island, and contiguous northern continental areas. It is one of 28 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789) from Geoscience Australia, depicting the extended continental shelf approved in April 2008, treaties, and various maritime zones. Background imagery combines 2009 bathymetry/topography from Geoscience Australia and a 1997 grid by Smith and Sandwell.

Use Cases

• Analyze maritime boundaries and treaties based on the depicted jurisdiction zones.
• Study the extent of Australia's approved continental shelf based on the 2008 Commission decision.
• Reference bathymetric and topographic features for northern Australian marine regions based on the combined background grids.
• Produce large-format plots for legal or educational display based on the 42-inch plotter-sized PDF.

Strengths

• Map is part of a standardized series of 28 constituent maps, suggesting systematic coverage.
• Background combines specific data sources: Geoscience Australia's 2009 9 arc-second grid and the 1997 Smith and Sandwell grid.
• Physical dimensions (3277mm x 1050mm) are specified for large-format plotting.

Limitations

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