Australia-Timor-Leste Maritime Boundary Treaty Data, 2019

Geoscience Australia developed this digital representation of the maritime boundary treaty ratified with Timor-Leste on 30 August 2019. The data covers a geographical extent between approximately 9.5°S to 11.5°S latitude and 126°E to 128.5°E longitude, supplied in the GDA94 datum. It is part of the 2019 epoch of the Australian Maritime Boundaries database, published in consultation with other Commonwealth agencies.

Use Cases

• Visualizing the ratified maritime boundary between Australia and Timor-Leste based on the treaty coordinates.
• Integrating treaty boundaries into maritime jurisdiction systems based on the described geospatial format.
• Conducting spatial analysis of the treaty area based on the specified latitude and longitude limits.

Strengths

• Data is tied to a specific ratified treaty with a known date of 30 August 2019.
• Geographical extent is explicitly defined with latitude and longitude limits.
• Coordinates are supplied in a standard datum (GDA94), operationally equivalent to WGS84.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description includes a disclaimer that the digital data may be overridden by the treaty text in case of inconsistency.
