Australia's Maritime Jurisdiction Map for Tasmania and Macquarie Island

A geospatial map depicting Australia's maritime jurisdiction around the State of Tasmania, including Macquarie Island. The map is part of a 27-map series and shows the extended continental shelf approved in 2008, treaties, and maritime zones over a bathymetric background. The Australian Ocean Data Network provides the map in A0 portrait PDF format.

Use Cases

• Delimit maritime boundaries for legal or policy analysis based on depicted jurisdiction zones and treaties.
• Analyze seabed topography for marine research based on the combined bathymetric and topographic grid background.
• Visualize the extent of Australia's continental shelf claims for educational or reference purposes based on the approved 2008 limits.

Strengths

• Map is part of a standardized 27-map series (GeoCat 71789), suggesting consistent cartographic methodology.
• Background bathymetry is derived from a specific 2009 9 arc second grid and a 1997 grid by Smith and Sandwell, providing a defined data source.
• Jurisdictional boundaries are based on a defined legal event: the Commission on the Limits of the Continental Shelf approval in April 2008.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided as a static PDF map, limiting direct machine-readability and analysis compared to vector or raster formats.
• Freshness should be verified; the underlying bathymetric and treaty data may have updates beyond the map's creation.
