Australia's Maritime Jurisdiction Map with 2020 Treaty Updates

A March 2020 wall map from Geoscience Australia depicts Australia's maritime jurisdiction, including the extended continental shelf approved in 2008. The map uses a blue Etopo2 seabed background and NASA Blue Marble land imagery, updated to reflect the 2018 Australia-Timor-Leste Maritime Boundaries Treaty. It is described as indicative only and not a definitive source, with some limits subject to change.

Use Cases

• Visualizing maritime boundaries for educational or reference purposes based on the described map imagery.
• Referencing the 2018 Australia-Timor-Leste treaty line for geopolitical analysis based on the update mentioned.
• Studying the extent of Australia's approved continental shelf based on the 2008 Commission approval referenced.

Strengths

• Includes a major update from March 2020 reflecting the 2018 Australia-Timor-Leste treaty.
• Integrates multiple authoritative data sources: Etopo2 seabed data and NASA Blue Marble imagery.
• Based on the extended continental shelf limits approved by the UN Commission in April 2008.

Limitations

• The map is explicitly described as 'indicative only' and 'should NOT be used as a definitive source of information'.
• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
