Australia's Maritime Jurisdiction Map of Tasmania with Bathymetry

A geospatial map depicting Australia's maritime jurisdiction around Tasmania, including the South Tasman Rise and Victoria. The map is part of a 27-map series and shows the extended continental shelf approved in 2008, along with various maritime zones. Background imagery combines bathymetric data from Geoscience Australia (2009) and Smith and Sandwell (1997) with land imagery from NASA's Blue Marble.

Use Cases

• Analyze maritime legal boundaries based on the depicted extended continental shelf and maritime zones.
• Study ocean floor topography based on the combined bathymetric grid background.
• Create reference maps for regional maritime planning based on the Lambert Conformal Conic Projection.
• Integrate jurisdictional data with other marine datasets based on the defined geographic scope around Tasmania.

Strengths

• Map is part of a standardized 27-map series (GeoCat 71789), suggesting consistent methodology.
• Background bathymetry is derived from two specific sources: a 2009 9 arc-second grid and a 1997 grid by Smith and Sandwell.
• Depicts legally significant features, including the continental shelf boundary approved by the UN 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 for quantitative analysis.
• Data may reflect geographic bias inherent to data_gov_au, focusing solely on Australian claims.
