Australia's Maritime Jurisdiction Map for Northern Australia, 2014

One of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789). The map depicts Australia's continental shelf as proclaimed in the 2012 proclamation, updated in June 2014 to conform with 'Australian Maritime Boundaries 2014' data from Geoscience Australia. Background imagery combines bathymetry from Geoscience Australia's 2009 grid and a 1997 grid by Smith and Sandwell, with land imagery from NASA's Blue Marble.

Use Cases

• Delineate maritime boundaries for legal and policy analysis based on the proclaimed continental shelf.
• Analyze bathymetric features for marine spatial planning using the combined background grid data.
• Reference jurisdictional extents for environmental management in areas contiguous to northern Australia.
• Produce large-format maps for official or educational purposes based on the 2800mm x 1050mm plotter-sized PDF.

Strengths

• Based on authoritative legal and geospatial sources: the 'Seas and Submerged Lands Act 1973' and Geoscience Australia's 2014 boundaries.
• Integrates multiple data sources for context, including bathymetry from 2009 and 1997 grids and NASA land imagery.
• Part of a standardized series of 27 maps, suggesting consistent methodology.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2026-04-30 14:01:10.582952; freshness should be verified as the underlying legal data is from 2014.
• Spatial coverage excludes areas around Cocos (Keeling) Islands and areas west of Christmas Island.
