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 as 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 is derived from a 2009 9 arc second grid by Geoscience Australia and a 1997 grid by Smith and Sandwell.

Use Cases

• Analyze maritime boundary claims based on depicted extended continental shelf and maritime zones.
• Study bathymetric features for oceanographic research using the combined background grid.
• Reference treaty-defined zones for legal or diplomatic purposes based on the map's depiction.
• Plan marine resource management activities within Australia's jurisdiction around Tasmania.

Strengths

• Part of a standardized series of 27 maps providing consistent jurisdictional coverage.
• Based on an authoritative continental shelf boundary approved by the UN Commission in April 2008.
• Integrates bathymetric data from two specific sources: a 2009 GA 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.
• Freshness should be verified; the underlying bathymetric data sources are from 2009 and 1997.
