Maritime Jurisdiction Map of Tasmania with Bathymetric Background

Australia's Maritime Jurisdiction around Tasmania is a geospatial map depicting the extended continental shelf and maritime zones. It is one of 27 maps in the national Maritime Jurisdiction Map Series, produced by the Australian Ocean Data Network. The map is based on a Mercator projection and uses bathymetric data from 2009 and 1997.

Use Cases

• Delineating the approved extended continental shelf boundary for legal and regulatory analysis.
• Analyzing bathymetric features from the combined GA and Smith/Sandwell grid for oceanographic modeling.
• Integrating maritime zone boundaries (e.g., Exclusive Economic Zone) with other marine spatial datasets.
• Studying the spatial relationship between jurisdictional claims and underwater topography like the South Tasman Rise.

Strengths

• Part of a standardized national map series comprising 27 constituent maps.
• Incorporates bathymetric data from two authoritative sources (GA 2009, Smith and Sandwell 1997).
• Based on a continental shelf submission approved by the UN Commission in April 2008.

Limitations

• Data is provided only as a static PDF/A0 map image, limiting machine-readability and analysis.
• The map excludes the Macquarie Ridge region, limiting complete geographic coverage around Tasmania.
• Underlying vector boundary data or attribute tables are not provided with the map file.

Provenance

Source

Australian Ocean Data Network, part of the Australia's Maritime Jurisdiction Map Series (GeoCat 71789).

Collection Method

Cartographic compilation based on legal submissions and processed bathymetric grids.

Time Range

Jurisdictional data reflects the 2008 Commission approval; bathymetry from 1997 and 2009.

Freshness

Map metadata was last updated in April 2026, but the underlying jurisdictional data is from 2008.

Geography

Maritime zones and continental shelf around Tasmania, including the South Tasman Rise and Victoria.
