Australia's Maritime Jurisdiction Map with 2020 Treaty Update

A March 2020 wall map from the Australian Ocean Data Network depicts Australia's maritime zones, including the extended continental shelf approved in April 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. The map is described as indicative only and not a definitive source, with some limits subject to change.

Use Cases

• Visualizing maritime boundary changes based on the 2018 Australia-Timor-Leste treaty mentioned in the description
• Referencing indicative continental shelf limits based on the 2008 Commission approval described
• Creating educational or reference materials based on the combined seabed and land imagery from Etopo2 and NASA

Strengths

• Updated in March 2020 to incorporate a 2018 international treaty.
• Combines two authoritative data sources: Etopo2 for seabed and NASA Blue Marble for land.

Limitations

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