Australia's Maritime Jurisdiction Map for Tasmania and South Tasman Rise

One of 27 constituent maps from the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789). The map depicts Australia's extended continental shelf approved by the UN Commission in April 2008, along with various maritime zones around Tasmania. Background bathymetry is derived from a 2009 9 arc second grid by Geoscience Australia and a 1997 grid by Smith and Sandwell.

Use Cases

• Visualize maritime boundaries and the extended continental shelf based on the 2008 UN Commission approval.
• Analyze bathymetric features around Tasmania using the combined 2009 and 1997 background grids.
• Reference jurisdictional extents for marine spatial planning in the South Tasman Rise region.

Strengths

• Part of a standardized series of 27 maps providing consistent jurisdictional coverage.
• Based on authoritative legal and scientific data, including a 2008 UN Commission decision.
• Integrates bathymetric data from two specific sources: Geoscience Australia (2009) and Smith and Sandwell (1997).

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.
• The map excludes the Macquarie Ridge, limiting geographic completeness for the region.
