Treaties - Australian Maritime Boundaries 2014a: International Treaty Boundaries

A geospatial dataset provides a digital representation of Australia's international maritime boundaries determined by treaties with neighboring countries. It was published by Geoscience Australia in consultation with other Commonwealth agencies and updated in May 2014. The coverage spans the entire Australian marine jurisdiction, from approximately 8°S to 70°S latitude and 39°E to 174°E longitude.

Use Cases

• Analyze maritime claims and overlaps for legal or diplomatic purposes based on the treaty data.
• Integrate treaty boundaries with other marine spatial data for resource management planning.

Strengths

• Published by Geoscience Australia, the primary authority for Australia's maritime limits.
• Includes technical amendments based on user feedback, such as harmonization in block SC51.
• Coordinates are supplied in the GDA94 datum, which is 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.
