Treaty with Timor-Leste: Australian Maritime Boundaries 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. This digital representation covers a geographical extent between approximately 9.5°S to 11.5°S latitude and 126°E to 128.5°E longitude. The data is supplied in the GDA94 datum and is published in ESRI Geodatabase and Shapefile formats.

Use Cases

• Visualizing the ratified maritime boundary between Australia and Timor-Leste based on the treaty coordinates.
• Conducting spatial analysis for marine jurisdiction and resource management within the defined treaty area.
• Integrating treaty boundaries into broader maritime spatial information systems for legal and administrative purposes.

Strengths

• Includes the specific treaty ratified on 30 August 2019.
• Covers a defined geographical extent between 9.5°S to 11.5°S and 126°E to 128.5°E.
• Coordinates are supplied in the standardized GDA94 datum.

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.
