A geospatial map depicting Australia's continental shelf jurisdiction off the Northwest Shelf, as proclaimed in 2012. The map is one of 27 constituent maps in a national series and was updated in June 2014 to conform with authoritative boundary data. The background combines bathymetric imagery from Geoscience Australia and NASA.
Use Cases
- Analyze maritime boundary definitions based on the proclaimed continental shelf limits.
- Study bathymetric features of the Northwest Shelf region based on the combined background grid.
- Reference jurisdictional boundaries for legal or policy research based on the official map series.
- Integrate with other maritime datasets based on the 2014 Australian Maritime Boundaries standard.
Strengths
- Map is part of a 27-map national series providing consistent coverage.
- Updated in June 2014 to align with authoritative 'Australian Maritime Boundaries 2014' data.
- Background bathymetry derived from specific sources: a 2009 9 arc second grid and a 1997 grid by Smith and Sandwell.
Limitations
- Data format is a static A0-sized PDF, limiting direct geospatial analysis.
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated metadata is 2026-05-05; the actual data content is from 2014.
