Australia's Maritime Jurisdiction Map North of 25°S, Updated 2019

A geospatial map depicting Australia's maritime jurisdiction north of approximately 25°S, updated in December 2019. The update reflects the 2018 Australia/Timor-Leste Maritime Boundaries Treaty and incorporates Australia's continental shelf as proclaimed in 2012. Background imagery combines bathymetric data from Geoscience Australia and NASA's Blue Marble.

Use Cases

• Visualizing maritime treaty boundaries based on the 2018 Australia/Timor-Leste treaty mentioned in the description
• Analyzing continental shelf extents based on the 2012 proclamation referenced in the description
• Studying bathymetric features in northern Australian waters based on the combined grid data described
• Incorporating jurisdiction maps into a series based on the mention of 28 constituent maps

Strengths

• Updated in December 2019 to incorporate a specific international treaty (the 2018 Australia/Timor-Leste Maritime Boundaries Treaty)
• Includes jurisdiction areas for Cocos (Keeling) Islands and Christmas Island as stated in the description
• Background imagery is derived from specific, cited sources (Geoscience Australia 2009 grid and Smith & Sandwell 1997 grid)

Limitations

• Description metadata is limited; actual data quality and format require manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
