Australia's Maritime Jurisdiction Boundaries with Bathymetric Background

A geospatial map depicting Australia's continental shelf boundaries as proclaimed in the Seas and Submerged Lands Act 1973. The background bathymetric image combines data from Geoscience Australia's 2009 grid and Smith and Sandwell's 1997 grid, with land imagery from NASA's Blue Marble. It is one of 27 constituent maps in the Australia's Maritime Jurisdiction Map Series, updated in April 2021 to conform with Australian Maritime Boundaries 2020 data.

Use Cases

• Visualizing maritime legal boundaries based on the proclaimed continental shelf.
• Analyzing bathymetric data for oceanographic research based on the combined background grid.
• Creating jurisdictional reference maps for maritime policy and enforcement.
• Integrating legal boundaries with topographic data for coastal zone management.

Strengths

• Map is updated to conform with authoritative Australian Maritime Boundaries 2020 data.
• Background combines bathymetric data from two established sources (Geoscience Australia 2009 and Smith and Sandwell 1997).
• Part of a standardized series of 27 constituent maps.

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.
