Australia's Maritime Jurisdiction in the Tasman Sea with Bathymetric Background

One of 27 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. Background imagery combines a 2009 9 arc second bathymetric grid and a 1997 grid by Smith and Sandwell, with land imagery from NASA's Blue Marble.

Use Cases

• Visualizing maritime boundaries and zones based on depicted treaties and legal limits.
• Analyzing continental shelf extents based on the 2008 Commission-approved limits.
• Using bathymetric background for oceanographic or geological context in the Tasman Sea region.
• Referencing jurisdictional maps for marine spatial planning or legal research.

Strengths

• Part of a standardized series of 27 constituent maps providing systematic coverage.
• Background bathymetry is derived from specific, cited sources: a 2009 9 arc second grid and a 1997 grid by Smith and Sandwell.
• Maritime limits are based on an official 2008 approval by the Commission on the Limits of the Continental Shelf.

Limitations

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