Australia-Timor-Leste Maritime Boundary Treaty Data, 2019

Geoscience Australia developed the 2019 epoch of the Australian Maritime Boundaries database, which includes the treaty ratified with Timor-Leste on 30 August 2019. The data product is a digital representation of the maritime boundary treaty between the two nations, covering an area approximately between 9.5°S to 11.5°S latitude and 126°E to 128.5°E longitude. Data coordinates are supplied in the GDA94 datum and are published in ESRI Geodatabase and Shapefile formats.

Use Cases

• Visualizing the maritime boundary between Australia and Timor-Leste based on the 2019 treaty coordinates.
• Conducting spatial analysis of maritime zones for legal or resource management purposes.
• Integrating treaty boundaries with other marine spatial datasets for jurisdictional mapping.
• Validating maritime claims and limits against the official treaty representation.

Strengths

• Includes the specific treaty information ratified on 30 August 2019.
• Published by Geoscience Australia in consultation with other relevant Commonwealth Government agencies.
• Geographical extent is explicitly defined between 9.5°S to 11.5°S and 126°E to 128.5°E.
• Coordinates are supplied in the GDA94 datum, which is operationally 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.
• The dataset includes a disclaimer that the treaty text prevails over the digital data in case of inconsistency.
