Australia's Maritime Jurisdiction North of 25°S, Updated for 2018 Treaty

December 2019 map updates Australia's maritime jurisdiction to reflect the 2018 Australia/Timor-Leste Maritime Boundaries Treaty. This geospatial dataset is one of 28 constituent maps in the official series by Geoscience Australia, depicting the continental shelf as proclaimed in 2012. Background imagery combines bathymetric and topographic data from Geoscience Australia and NASA's Blue Marble.

Use Cases

• Analyze changes in maritime boundaries based on the 2018 Australia/Timor-Leste treaty mentioned in the description.
• Map Australia's continental shelf limits as defined in the 2012 proclamation referenced in the description.
• Integrate bathymetric and topographic background layers for oceanographic or geological studies.
• Study jurisdictional areas around Cocos (Keeling) Islands and Christmas Island as specified in the description.

Strengths

• Updated in December 2019 to incorporate a major international treaty (2018 Australia/Timor-Leste).
• Part of a standardized series of 28 constituent maps, suggesting systematic coverage.
• Background layers derived from authoritative sources like Geoscience Australia and NASA.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analysis.
• The map is sized for a 42-inch plotter (3277mm x 1050mm), which may require specific handling for digital analysis.
