Australia's Maritime Jurisdiction Map with Continental Shelf and Bathymetry

Geoscience Australia Data provides a map depicting Australia's maritime jurisdiction and extended continental shelf approved in April 2008. The A0-sized PDF combines bathymetric data from a 2009 grid and a 1997 source with NASA's Blue Marble land imagery. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series'.

Use Cases

• Visualizing maritime boundaries based on the depicted jurisdiction and continental shelf.
• Analyzing seabed topography based on the combined bathymetric background imagery.
• Referencing official continental shelf limits based on the 2008 Commission approval.
• Creating base maps for marine spatial planning based on the integrated land and sea imagery.

Strengths

• Depicts the extended continental shelf officially approved by the Commission on the Limits of the Continental Shelf in April 2008.
• Background bathymetry is derived from a combination of the 2009 9 arc second grid and a 1997 grid by Smith and Sandwell.
• One of 27 maps in a formal series (GeoCat 71789), suggesting a structured collection.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
