Australia's Maritime Jurisdiction Map for Heard and McDonald Islands

One of 27 constituent maps from the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789). This 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 Heard Island and McDonald Islands. The background uses bathymetric data from Smith and Sandwell (1997) and land imagery from NASA's Blue Marble.

Use Cases

• Analyze maritime boundaries and treaties based on the depicted jurisdictional zones.
• Study the extent of the continental shelf based on the approved 2008 submission to the CLCS.
• Create composite maps for the Antarctic region based on this map being part of a 27-map series.
• Visualize bathymetry around sub-Antarctic islands based on the Smith and Sandwell (1997) grid background.

Strengths

• Part of a standardized series of 27 maps, suggesting consistent methodology.
• Based on an official continental shelf submission approved by the CLCS in April 2008.
• Uses established background data sources: Smith and Sandwell (1997) bathymetry and NASA Blue Marble imagery.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
