AMB2014a: Australia's International Maritime Treaty Boundaries

Geoscience Australia's 2014a release provides a digital representation of Australia's international maritime boundaries determined by treaties. The dataset covers Australia's entire marine jurisdiction, including waters adjacent to the mainland, offshore islands, and External Territories. Coordinates are supplied in the GDA94 datum, and the data is available as an ESRI Geodatabase.

Use Cases

• Mapping maritime jurisdiction zones based on treaty-defined boundaries.
• Analyzing spatial relationships between Australia and neighboring countries based on treaty data.
• Supporting legal and policy research on international maritime agreements.
• Integrating treaty boundaries with other marine datasets for comprehensive jurisdictional analysis.

Strengths

• Developed by Geoscience Australia in consultation with other Commonwealth Government agencies.
• 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.
• Row count is unknown, which may limit suitability assessment.
