Australia's Maritime Jurisdiction Map for Heard and McDonald Islands

One of 27 constituent maps in 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. It is an A0-sized PDF using a Mercator projection with a WGS84 datum and background imagery from Smith and Sandwell (1997) and NASA's Blue Marble.

Use Cases

• Analyze maritime zone boundaries based on the depicted treaties and approved continental shelf limits.
• Study bathymetric features using the background grid derived from Smith and Sandwell, 1997.
• Reference jurisdictional extents for environmental or resource management planning around Heard Island and McDonald Islands.
• Compare cartographic projections using the specified Mercator projection with a central meridian of 76°E and true scale at 58°S.

Strengths

• Part of a standardized series of 27 maps providing consistent jurisdictional mapping.
• Based on an officially approved continental shelf submission from April 2008.
• Incorporates established background data sources: a bathymetric grid from Smith and Sandwell (1997) and land imagery from NASA's Blue Marble.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data format is a static PDF, limiting direct computational analysis without conversion.
• Freshness should be verified; the last update timestamp is 2026-04-30 14:13:39.018734.
