Australia's Maritime Jurisdiction Map of Tasmania with Bathymetric Background

One of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789). This map depicts Australia's extended continental shelf around Tasmania, as approved by the Commission on the Limits of the Continental Shelf in April 2008, and includes various maritime zones. The background bathymetric image is derived from a 2009 9 arc second grid and a 1997 grid by Smith and Sandwell.

Use Cases

• Analyze maritime zone boundaries based on the depicted extended continental shelf and jurisdictional lines.
• Study seabed topography for the South Tasman Rise region based on the combined bathymetric background.
• Reference legal and administrative maritime claims around Tasmania for policy or educational purposes.
• Integrate as a base layer for regional marine spatial planning based on the defined jurisdiction areas.

Strengths

• Part of a defined 27-map series (GeoCat 71789), providing structured context.
• Based on a specific legal decision (Commission approval in April 2008) for the continental shelf limits.
• Background bathymetry combines data from two specific sources (2009 GA grid and 1997 Smith and Sandwell grid).
• Available in a standardized, high-resolution A0 portrait PDF format for professional printing.

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.
• Data may reflect geographic bias inherent to data_gov_au, focusing solely on Australian claims.
