Australia's Maritime Zones and Boundaries Map, Edition 4 (2013)

Edition 4 of Australia's Maritime Zones map supersedes the 2006 edition and is derived from Geoscience Australia's Australian Maritime Boundaries version 2.0 data. The map shows Australia's territorial sea baseline, maritime limits, and the continental shelf limits confirmed in April 2008, including unresolved areas and the area off the Australian Antarctic Territory. It describes maritime zones, explains boundary definitions, and lists arrangements with Indonesia, Papua New Guinea, Solomon Islands, France, and New Zealand.

Use Cases

• Visualizing the extent of Australia's maritime jurisdiction based on the described zones and boundaries.
• Analyzing international maritime boundary agreements based on the listed arrangements with neighboring countries.
• Studying continental shelf limits and unresolved areas as confirmed by the Commission on the Limits of the Continental Shelf.
• Mapping Australia's territorial sea baseline derived from the Australian Maritime Boundaries data.

Strengths

• Derived from the authoritative Australian Maritime Boundaries (AMB) version 2.0 data from Geoscience Australia.
• Incorporates the continental shelf limits confirmed by an international commission on 9 April 2008.
• Explicitly lists 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 map's currency is noted as 2013, which may not reflect recent changes.
