Australia's Maritime Jurisdiction Map for Northern Australia

A geospatial map depicting Australia's maritime jurisdiction off Northern Australia. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789). The map shows the extended continental shelf approved in 2008, treaties, and various maritime zones, with background bathymetry and land imagery derived from Geoscience Australia and NASA sources.

Use Cases

• Analyze maritime zone boundaries based on treaties and continental shelf limits mentioned in the description
• Study bathymetric features in Northern Australian waters based on the combined 2009 and 1997 grids referenced
• Visualize jurisdictional areas contiguous to the continent and Christmas Island as described in the map scope
• Reference legal maritime boundaries for policy or regulatory work based on the depicted zones and treaties

Strengths

• Part of a standardized series of 27 maps (GeoCat 71789), suggesting systematic coverage
• Background imagery derived from authoritative sources: Geoscience Australia (2009) and Smith & Sandwell (1997) bathymetry, plus NASA Blue Marble
• Map dimensions are specified (2800mm x 1050mm) for a 42-inch plotter, indicating production for high-resolution output

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 only on Northern Australia and excluding Cocos (Keeling) Islands
