Australia's Maritime Zones and Continental Shelf Limits, 2013

Edition 4, published in 2013, supersedes the 2006 map. This digital map, derived from Geoscience Australia's Australian Maritime Boundaries version 2.0, shows Australia's territorial sea baseline, maritime limits, and confirmed continental shelf limits. It details maritime zones, boundary arrangements with neighboring nations, and covers an area from Heard and McDonald Islands to Norfolk Island and the Australian Antarctic Territory.

Use Cases

• Visualizing maritime legal jurisdictions based on the described territorial sea baseline and maritime limits.
• Analyzing continental shelf claims based on the limits confirmed by the UN Commission in 2008.
• Studying international maritime boundary agreements based on the listed arrangements with Indonesia, Papua New Guinea, and others.
• Mapping the extent of Australia's maritime zones from the Antarctic Territory to the Torres Strait as described.

Strengths

• Derived from the authoritative Australian Maritime Boundaries (AMB) version 2.0 dataset.
• Incorporates continental shelf limits confirmed by the UN Commission on the Limits of the Continental Shelf on 9 April 2008.
• Details specific maritime boundary arrangements with five neighboring countries or territories.

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.
• The underlying data currency is 2013, which may not reflect recent changes.
