One of 27 constituent maps in the Australia's Maritime Jurisdiction Map Series, depicting the extended continental shelf approved by the Commission on the Limits of the Continental Shelf in April 2008. The map shows areas contiguous to northern Australia, including west to Christmas Island, and excludes areas around Cocos (Keeling) Islands. Background bathymetry is derived from a 2009 Geoscience Australia grid and a 1997 grid by Smith and Sandwell.
Use Cases
- Analyze maritime boundaries and jurisdiction based on depicted treaties and maritime zones
- Study the extent of Australia's continental shelf based on the 2008 CLCS approval
- Visualize bathymetric features off northern Australia using the combined background grid data
- Reference jurisdictional limits for marine spatial planning in the specified region
Strengths
- Part of a standardized 27-map series (GeoCat 71789) providing consistent coverage
- Integrates authoritative legal boundaries (2008 CLCS approval) with scientific bathymetry data
- Background imagery combines high-resolution (2009 9 arc second) and established (1997 Smith & Sandwell) data sources
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
- Row count is unknown, which may limit suitability assessment
