Australia's Maritime Jurisdiction in the Tasman Sea, A0 Map

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. Background imagery combines bathymetric data from 2009 and 1997 sources with land imagery from NASA's Blue Marble.

Use Cases

• Visualizing maritime boundaries and zones based on the depicted treaties and continental shelf limits.
• Analyzing bathymetric features of the Tasman Sea based on the combined 2009 and 1997 background grid.
• Referencing the officially approved extended continental shelf limits for legal or policy research.
• Incorporating base map layers for regional marine spatial planning based on the A0-scale geospatial data.

Strengths

• Part of a standardized series of 27 maps providing consistent jurisdictional coverage.
• Based on an extended continental shelf approval from a specific date (April 2008).
• Background bathymetry derived from two specific sources: a 2009 9 arc-second grid and a 1997 grid by Smith and Sandwell.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided as a static A0 PDF map, limiting direct machine-readability and analysis.
• Row count is unknown, which may limit suitability assessment for quantitative applications.
