Australia-Timor-Leste Maritime Boundary Treaty: 2019 Geospatial Data

September 2019 data provides a digital representation of the maritime boundary treaty between Australia and Timor-Leste, ratified on 30 August 2019. The dataset is part of the Australian Maritime Boundaries (AMB) database, published by Geoscience Australia in consultation with other government agencies. It covers a geographical extent approximately between 9.5°S to 11.5°S latitude and 126°E to 128.5°E longitude, supplied in the GDA94 datum as ESRI Geodatabase and Shapefile formats.

Use Cases

• Delineating national maritime jurisdiction for legal and administrative purposes based on the ratified treaty.
• Conducting marine spatial planning and resource management within the defined boundary area.
• Supporting international law and diplomacy research with an official digital representation of the treaty.
• Integrating treaty boundaries into larger geospatial systems for maritime domain awareness.

Strengths

• Represents the official 2019 epoch of the Australian Maritime Boundaries database, incorporating a specific ratified treaty.
• Published by the authoritative national agency, Geoscience Australia, in consultation with other key government departments.
• Provides a precise geographical extent and coordinate datum (GDA94), allowing for accurate geospatial analysis.

Limitations

• Metadata completeness is low: specific column names, row counts, file size, license, and author information are not provided.
• A disclaimer notes the data is a digital representation and the treaty text prevails in case of inconsistency.
• The temporal coverage is a single snapshot (September 2019), lacking a historical time series of boundary changes.
