Australia's Maritime Jurisdiction Map Series: Tasmania Region

One of 27 constituent maps in 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 Tasmania and Macquarie Island. Background bathymetry combines the 2009 9 arc second grid by Geoscience Australia with a 1997 grid by Smith and Sandwell.

Use Cases

• Analyze maritime boundary definitions based on the depicted extended continental shelf and maritime zones.
• Study bathymetric features around Tasmania based on the combined GA and Smith & Sandwell background grid.
• Reference treaty-defined zones for legal or jurisdictional research based on the map's annotations.

Strengths

• Part of a standardized series of 27 maps providing consistent coverage.
• Based on an officially approved continental shelf definition from April 2008.
• Integrates bathymetric data from two authoritative sources: Geoscience Australia (2009) and Smith & Sandwell (1997).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic or source bias inherent to data_gov_au.
