Australia's Maritime Boundaries North of 25°S

Australia's Maritime Jurisdiction North of 25°S 2019 is a high-resolution map depicting Australia's maritime boundaries, including its continental shelf and exclusive economic zone. The map was updated in December 2019 to incorporate the 2018 Australia/Timor-Leste Maritime Boundaries Treaty and is part of a 28-map series by Geoscience Australia. It includes areas around Cocos (Keeling) Islands and Christmas Island, with background imagery derived from bathymetric and topographic data.

Use Cases

• [Verifying treaty compliance] based on [the 2018 Australia/Timor-Leste Maritime Boundaries Treaty incorporation]
• [Delineating resource exploration zones] based on [the proclaimed continental shelf limits from 2012]
• [Creating thematic marine maps] based on [the bathymetry and land imagery background layers]
• [Analyzing jurisdictional changes] based on [the documented updates from 2014 and 2019]

Strengths

• [Official source] based on [data from Geoscience Australia and the Seas and Submerged Lands Act 1973]
• [Specific treaty incorporation] based on [update to reflect the 2018 Australia/Timor-Leste Maritime Boundaries Treaty]
• [High-resolution output] based on [a 3277mm x 1050mm PDF designed for a 42-inch plotter]
• [Part of a comprehensive series] based on [being one of 28 constituent maps in the Australia's Maritime Jurisdiction Map Series]

Limitations

• [Incomplete metadata] based on [missing column definitions, row counts, license, and author information across all platform entries]
• [Potential format limitation] based on [primary downloadable file being a static PDF map, which may limit direct geospatial analysis]
• [Spatial incompleteness] based on [coverage limited to areas north of approximately 25°S, excluding southern maritime zones]
