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

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. It was produced by the Australian Ocean Data Network, with a background bathymetric image derived from a 2009 9 arc-second grid and a 1997 grid by Smith and Sandwell.

Use Cases

• Analyze maritime boundaries and treaties based on depicted jurisdictional zones.
• Study seafloor topography based on the combined bathymetric background imagery.
• Reference the extent of Australia's continental shelf in the Tasman Sea for legal or environmental research.

Strengths

• Part of a defined 27-map series (GeoCat 71789), providing contextual structure.
• Background bathymetry combines data from two specific sources (2009 GA grid and 1997 Smith and Sandwell grid).
• Depicts a legally defined feature (continental shelf) approved by an international commission in April 2008.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing solely on Australian jurisdiction.
