Australia's Maritime Jurisdiction Map for Northern Australia

Australia's Maritime Jurisdiction off Northern Australia is a geospatial map depicting the country's extended continental shelf, treaties, and maritime zones. The map is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' and is sized for a 42-inch plotter at 2800mm x 1050mm. Background imagery combines bathymetry data from Geoscience Australia (2009) and Smith & Sandwell (1997) with land imagery from NASA's Blue Marble.

Use Cases

• Analyze maritime boundary extents based on the depicted continental shelf and treaty zones.
• Study bathymetric features of the seafloor based on the combined 9 arc second and Smith & Sandwell grids.
• Create reference maps for maritime legal or environmental planning based on the official jurisdiction areas.

Strengths

• Part of a standardized 27-map series (GeoCat 71789) providing consistent jurisdictional coverage.
• Background bathymetry derived from two authoritative sources: Geoscience Australia (2009) and Smith & Sandwell (1997).
• Map dimensions (2800mm x 1050mm) are specified for high-resolution plotting.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided as a static PDF/HTML map, limiting direct geospatial analysis without conversion.
• The description excludes areas around Cocos (Keeling) Islands and west of Christmas Island, indicating incomplete regional coverage.
