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

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, and various maritime zones around Tasmania. Background bathymetry is derived from a 2009 9 arc second grid and a 1997 grid by Smith and Sandwell, with land imagery from NASA's Blue Marble.

Use Cases

• Visualizing maritime legal boundaries based on the depicted extended continental shelf and maritime zones.
• Analyzing seafloor topography for the region based on the combined bathymetric background imagery.
• Producing reference maps for the South Tasman Rise area based on the Lambert Conformal Conic Projection.
• Studying the spatial relationship between Tasmania, Victoria, and Australia's maritime claims.

Strengths

• Part of a defined 27-map series (GeoCat 71789) providing structured coverage.
• Based on a specific legal framework, with the continental shelf limits approved in April 2008.
• Background bathymetry combines a 2009 9 arc second grid with a 1997 grid by Smith and Sandwell.

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 primary downloadable format is a static A0-sized PDF, which may limit direct machine-readability.
