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, treaties, and various maritime zones around Heard Island and McDonald Islands. Background bathymetry is derived from Smith and Sandwell (1997), and land imagery from NASA's Blue Marble.

Use Cases

• Study continental shelf extents based on the approved 2008 submission.
• Visualize bathymetric features based on the Smith and Sandwell 1997 grid.
• Reference jurisdictional claims in the Antarctic region based on the map's coverage.

Strengths

• Part of a standardized series of 27 maps for consistent jurisdictional reference.
• Based on an officially approved continental shelf submission from April 2008.
• Incorporates authoritative background data from Smith and Sandwell (1997) and NASA.

Limitations

• Metadata completeness is limited; column-level documentation is absent.
• The data format is a static PDF/A0 map, which may limit quantitative analysis.
