Australia's Maritime Jurisdiction Map for Macquarie Island

One of the 27 constituent maps of the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789). The map depicts Australia's extended continental shelf, approved by the Commission on the Limits of the Continental Shelf in April 2008, along with treaties and various maritime zones around Macquarie Island. The background bathymetric image is derived from a combination of the 2009 9 arc second grid by Geoscience Australia and a 1997 grid by Smith and Sandwell.

Use Cases

• Analyze maritime boundary claims and treaties based on the depicted jurisdiction zones.
• Study the extent of the continental shelf based on the approved 2008 limits.
• Incorporate bathymetric data for oceanographic modeling based on the combined GA and Smith & Sandwell grid.
• Produce reference maps for legal or educational purposes based on the A0 portrait format PDF.

Strengths

• Part of a standardized series of 27 maps providing consistent coverage.
• Based on an extended continental shelf approval from a recognized international commission in April 2008.
• Incorporates bathymetric data from two specific sources: a 2009 Geoscience Australia grid and a 1997 Smith and Sandwell grid.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
• Data may reflect geographic bias inherent to data_gov_au, focusing solely on Australian jurisdiction.
