Australia's Maritime Jurisdiction Map for Macquarie Island

One of the 27 constituent maps of the Australia's Maritime Jurisdiction Map Series (GeoCat 71789). The map depicts Australia's extended continental shelf, approved by the Commission on the Limits of the Continental Shelf in April 2008, along with treaties and various maritime zones around Macquarie Island. Background bathymetric imagery is derived from a combination of the 2009 9 arc second grid by Geoscience Australia and a 1997 grid by Smith and Sandwell.

Use Cases

• Define maritime boundaries based on the depicted extended continental shelf and maritime zones.
• Analyze ocean floor topography using the background bathymetric imagery.

• Create derivative maps for regional environmental or economic planning.

Strengths

• Part of a standardized national map series comprising 27 constituent maps.
• Based on authoritative sources including a 2008 Commission approval and bathymetric grids from Geoscience Australia (2009) and Smith and Sandwell (1997).
• Available in a high-resolution, print-ready A0 portrait PDF format.
