Australia's Maritime Jurisdiction in the Timor Sea, A0 Map with Bathymetry

A geospatial map depicting Australia's maritime jurisdiction in the Timor Sea. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789), produced by Geoscience Australia. The map shows the extended continental shelf approved in 2008, treaty boundaries, and various maritime zones over a background of combined bathymetric and topographic imagery.

Use Cases

• Visualizing maritime boundaries and treaty zones based on the depicted jurisdiction and treaties.
• Analyzing continental shelf extents based on the 2008 Commission-approved limits.
• Incorporating bathymetric background for marine spatial planning based on the described derived grids.
• Referencing jurisdictional claims for legal or diplomatic research based on the treaty and zone information.

Strengths

• Part of a standardized series of 27 maps, suggesting consistent methodology.
• Background incorporates bathymetric data from two specific sources: a 2009 9 arc-second grid and a 1997 grid by Smith and Sandwell.
• Based on a formal continental shelf submission approved by the Commission on the Limits of the Continental Shelf in April 2008.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided as a static A0 PDF, limiting direct machine-readability and analysis.
• Freshness should be verified; the map's underlying legal and bathymetric data may be outdated despite the 2026 metadata update.
