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

A map depicting Australia's maritime jurisdiction north of approximately 25°S, updated in December 2019 to reflect the 2018 Australia/Timor-Leste Maritime Boundaries Treaty. The map is part of a series by Geoscience Australia and includes areas around Cocos (Keeling) Islands, Christmas Island, and the northern continent, with background bathymetry and land imagery derived from multiple sources.

Use Cases

• Visualizing maritime boundaries for legal and diplomatic reference based on the described treaty updates.
• Analyzing continental shelf extents for resource management based on the proclamation cited in the description.
• Incorporating jurisdictional basemaps for marine spatial planning based on the included island and coastal areas.
• Studying bathymetric data integration for oceanographic research based on the described background grid sources.

Strengths

• Updated in December 2019 to incorporate a specific international treaty (the 2018 Australia/Timor-Leste Maritime Boundaries Treaty).
• Part of a standardized map series (one of 28 constituent maps) maintained by Geoscience Australia.
• Background imagery combines data from Geoscience Australia (2009) and Smith & Sandwell (1997), suggesting a multi-source approach.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The map is provided as a large-format PDF (3277mm x 1050mm), which may not be directly machine-readable for analysis.
