Australia's Maritime Jurisdiction Map for Northern Australia, 2014

June 2014 map depicting Australia's maritime jurisdiction off its northern coast, updated to conform with the Australian Maritime Boundaries 2014 dataset. The map is one of 27 constituent maps in the Australia's Maritime Jurisdiction Map Series, produced by Geoscience Australia. It shows the continental shelf as proclaimed in 2012, with background imagery derived from bathymetry and NASA's Blue Marble.

Use Cases

• Analyze maritime boundary definitions based on the proclaimed continental shelf limits.
• Study bathymetric features off northern Australia based on the combined background grid data.
• Reference jurisdictional extents for marine spatial planning based on the map's depicted areas.
• Compare maritime zones around Christmas Island versus excluded Cocos (Keeling) Islands based on the described coverage.

Strengths

• Map is part of a standardized 27-map series (GeoCat 71789), suggesting systematic coverage.
• Background combines high-resolution data sources: a 2009 9 arc second bathymetry grid and a 1997 grid by Smith and Sandwell.
• Jurisdictional data is aligned with official 2014 maritime boundaries and a 2012 proclamation.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to data_gov_au, focusing on specific northern and western areas.
