Australia's Maritime Jurisdiction Map of Tasmania with Bathymetric Background

A geospatial map depicting Australia's maritime jurisdiction around Tasmania, including the South Tasman Rise and Victoria. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789) and shows the extended continental shelf approved in April 2008. The background combines bathymetric data from Geoscience Australia (2009) and Smith and Sandwell (1997) with land imagery from NASA's Blue Marble.

Use Cases

• Visualizing maritime legal boundaries based on the depicted extended continental shelf and maritime zones.
• Analyzing seafloor topography for the region based on the combined bathymetric background data.
• Producing reference maps for marine spatial planning using the A0 portrait format and Lambert projection.
• Studying the geographic extent of Australia's jurisdiction as part of the larger 27-map series.

Strengths

• Based on the extended continental shelf formally approved by the Commission on the Limits of the Continental Shelf in April 2008.
• Integrates multiple authoritative data sources, including a 2009 9 arc-second grid from Geoscience Australia and a 1997 grid by Smith and Sandwell.
• Part of a structured series of 27 maps providing consistent coverage of Australia's maritime jurisdiction.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided only in PDF and HTML formats, which may limit computational analysis.
• The description does not specify the exact spatial resolution or scale of the source bathymetric grids.
