Australia's Maritime Jurisdiction Map Off Northern Australia

One of 27 constituent maps in the Australia's Maritime Jurisdiction Map Series, depicting maritime zones and the extended continental shelf approved by the Commission on the Limits of the Continental Shelf in April 2008. The map covers areas north of the Australian continent and west to Christmas Island, excluding Cocos (Keeling) Islands. Background imagery combines bathymetry from Geoscience Australia (2009) and Smith & Sandwell (1997) with NASA's Blue Marble land imagery.

Use Cases

• Visualize maritime boundaries and jurisdiction based on the described treaty and zone information.
• Analyze bathymetric data for oceanographic research based on the combined 9 arc second and Smith & Sandwell grids.
• Reference the approved extended continental shelf limits for legal or diplomatic purposes.
• Study coastal and marine geography off Northern Australia using the high-resolution map imagery.

Strengths

• Part of a standardized series of 27 maps, suggesting consistent methodology.
• Integrates multiple authoritative data sources: Geoscience Australia bathymetry, Smith & Sandwell grid, and NASA Blue Marble.
• Based on an internationally recognized legal framework (Commission on the Limits of the Continental Shelf approval in April 2008).
• Provides a large-format (2800mm x 1050mm) PDF suitable for detailed plotting.

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 Australian regions.
