Australia's Maritime Jurisdiction Map North of 25°S

One map in a series of 28 depicting Australia's maritime jurisdiction north of approximately 25°S. The map was updated in December 2019 to incorporate the 2018 Australia/Timor-Leste Maritime Boundaries Treaty and is produced by Geoscience Australia. It includes areas around the Cocos (Keeling) Islands, Christmas Island, and the northern continental shelf.

Use Cases

• Analyze changes in maritime boundaries by comparing the 2019 update, which includes the Timor-Leste treaty, with the previous 2014 version.
• Visualize the extent of Australia's continental shelf as proclaimed in the 2012 proclamation using the provided geospatial boundaries.
• Study jurisdictional areas around specific territories like the Cocos (Keeling) Islands and Christmas Island from the map's geospatial features.
• Use the integrated bathymetry data from Geoscience Australia and Smith & Sandwell grids for oceanographic or seabed terrain analysis.

Strengths

• Updated in December 2019 to reflect a major international treaty, the 2018 Australia/Timor-Leste Maritime Boundaries Treaty.
• Part of a standardized series of 28 constituent maps, ensuring consistent cartographic methodology.
• Incorporates authoritative bathymetry data from Geoscience Australia's 2009 grid and the Smith & Sandwell 1997 global model.

Limitations

• The primary data is a static PDF map sized for a 42-inch plotter (3277mm x 1050mm), not a machine-readable geospatial vector dataset.
• Spatial coverage is limited to areas north of approximately 25°S, excluding southern Australian maritime zones.
• The underlying legal proclamations (e.g., 2012) may be older than the map's 2019 cartographic update.
