Maritime Jurisdiction Map of Tasmania and Macquarie Island

2026-03-07 updated map depicts Australia's maritime jurisdiction around Tasmania and Macquarie Island. It is one of 27 constituent maps in the national series, showing the extended continental shelf approved in April 2008, treaties, and maritime zones. The background bathymetry combines 2009 9 arc-second and 1997 Smith and Sandwell grids.

Use Cases

• Analyze the spatial extent of the extended continental shelf feature around Tasmania for maritime boundary studies.
• Use the bathymetric background layer for coastal and marine spatial planning in the AU-TAS region.
• Reference the depicted maritime zones and treaty boundaries for legal or administrative boundary analysis.
• Integrate this map with other series constituents using the GeoCat 71789 series identifier for a national jurisdictional overview.

Strengths

• Part of a standardized national series of 27 maritime jurisdiction maps.
• Includes bathymetric data derived from 2009 9 arc-second and 1997 authoritative grids.
• Depicts legally significant features like the continental shelf approved by the CLCS in April 2008.

Limitations

• Data is provided only as a static A0 portrait PDF map, not as machine-readable geospatial vectors or tabular data.
• The underlying bathymetric grid has components from 1997 and 2009, which may not reflect latest seafloor measurements.
• Sample data and column definitions are unavailable, limiting direct analytical use.
