Australia-Timor-Leste Maritime Boundary Treaty Coordinates, 2019

Geoscience Australia developed the Australian Maritime Boundaries (AMB) database, which includes a digital representation of the maritime boundary treaty ratified with Timor-Leste on 30 August 2019. The data product contains treaty coordinates in the GDA94 datum, covering an approximate geographical extent between 9.5°S to 11.5°S latitude and 126°E to 128.5°E longitude. It is published in consultation with other Commonwealth agencies and is accessible via the Australian Maritime Spatial Information System (AMSIS).

Use Cases

• Visualizing maritime treaty boundaries based on the described geographical extent coordinates.
• Integrating treaty data into maritime jurisdiction mapping systems based on the AMB database framework.
• Analyzing the spatial implications of international agreements based on the treaty's digital representation.
• Conducting legal or policy research on Australia-Timor-Leste relations based on the ratified treaty information.

Strengths

• Includes the specific treaty ratified on 30 August 2019.
• Coordinates are supplied in the GDA94 datum, which is operationally equivalent to WGS84.
• Geographical extent is explicitly defined as approximately between 9.5°S to 11.5°S and 126°E to 128.5°E.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is a digital representation; the description notes that treaty limits prevail in case of inconsistency.
