Australia's Maritime Jurisdiction Map for South Australia with Bathymetry

A geospatial map depicting Australia's maritime jurisdiction off the coast of South Australia. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789), showing the extended continental shelf approved in April 2008 and various maritime zones. The background bathymetry combines 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

• Analyze maritime zone boundaries based on the depicted extended continental shelf and jurisdictional lines.
• Study seafloor topography for the region based on the combined bathymetric background image.
• Reference jurisdictional claims for legal or policy research based on the approved continental shelf limits.

Strengths

• Part of a standardized series of 27 maps providing consistent coverage.
• Integrates bathymetric data from multiple sources, including a 2009 9 arc-second grid.
• Based on the extended continental shelf formally approved by the CLCS in April 2008.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified; the last update timestamp is 2026-06-27 20:43:00.285867.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
