Australia's Maritime Jurisdiction Map with Continental Shelf and Bathymetry

One map from the 27-constituent 'Australia's Maritime Jurisdiction Map Series'. It depicts Australia's extended continental shelf as approved by the Commission on the Limits of the Continental Shelf in April 2008. The background combines bathymetric data from a 2009 9 arc second grid and a 1997 grid by Smith and Sandwell, with land imagery from NASA's Blue Marble.

Use Cases

• Visualizing maritime jurisdictional boundaries based on the approved continental shelf limits.
• Analyzing seabed topography based on the combined bathymetric grid data mentioned in the description.
• Referencing official maritime zones for legal or policy research based on the map series.
• Creating base maps for marine spatial planning based on the integrated bathymetric and topographic background.

Strengths

• Part of a defined 27-map series (GeoCat 71789), providing contextual structure.
• Integrates multiple authoritative data sources: a 2009 GA bathymetric grid, a 1997 Smith and Sandwell grid, and NASA Blue Marble imagery.
• Based on a formally approved continental shelf boundary from April 2008.

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.
• Excludes specific territories like Cocos Island, subantarctic territories, and the AAT.
