AMB2014a: Australia's International Maritime Treaty Boundaries

Geoscience Australia's Treaties - Australian Maritime Boundaries Dataset 2014a is a digital representation of Australia's international maritime boundaries determined by treaties with neighbouring countries. The dataset covers the entire Australian marine jurisdiction, including waters adjacent to the mainland, offshore islands, and External Territories, with a geographical extent from approximately 8°S to 70°S and 39°E to 174°E. It was published in May 2014, with coordinates supplied in the GDA94 datum.

Use Cases

• Mapping maritime jurisdiction zones based on treaty-defined boundaries.
• Analyzing spatial relationships between Australia and neighbouring countries based on treaty coordinates.
• Integrating treaty boundaries with other maritime datasets like scheduled areas or graticular blocks.
• Visualizing Australia's marine jurisdiction for legal or policy purposes.

Strengths

• Developed by Geoscience Australia in consultation with Commonwealth agencies including the Attorney-General's Department.
• Contains technical amendments based on user feedback, including harmonization in block SC51.
• Coordinates are supplied in the GDA94 datum, functionally equivalent to WGS84.

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.
• In the event of an inconsistency between this data and treaty limits, the treaty prevails.
