Australia's Maritime Jurisdiction Map North of 25 Degrees South

One of 28 constituent maps in the Australia's Maritime Jurisdiction Map Series, this geospatial dataset depicts maritime zones north of approximately 25°S. It includes Australia's extended continental shelf approved by the Commission on the Limits of the Continental Shelf in April 2008, along with treaty boundaries and background bathymetry from Geoscience Australia and NASA. The map is produced by the Australian Ocean Data Network and is available as a 3277mm x 1050mm PDF sized for a 42-inch plotter.

Use Cases

• Analyze maritime boundaries and exclusive economic zones based on depicted treaty lines and jurisdictional areas.
• Study the extent of Australia's continental shelf for geological and resource assessment based on the 2008 CLCS approval.
• Create thematic maps for marine spatial planning using the combined bathymetry and land imagery background.
• Compare jurisdictional claims in the Indian Ocean region around Cocos (Keeling) Islands and Christmas Island.

Strengths

• Part of a standardized series of 28 constituent maps, suggesting systematic coverage.
• Background bathymetry is derived from authoritative sources including Geoscience Australia's 2009 9 arc second grid.
• Includes legally defined maritime zones based on a 2008 Commission on the Limits of the Continental Shelf approval.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to data_gov_au, focusing solely on Australian claims.
• Freshness should be verified; the underlying treaty and continental shelf data may have evolved since the map's creation.
