Australia's Maritime Jurisdiction Map for Macquarie Island, Mercator Projection

Geoscience Australia Data provides a map depicting Australia's maritime jurisdiction around Macquarie Island. The map is part of a 27-map series and shows the extended continental shelf approved in 2008, treaties, and various maritime zones. The background bathymetry combines data from a 2009 Geoscience Australia grid and a 1997 grid by Smith and Sandwell.

Use Cases

• Analyze maritime boundaries and territorial claims based on the depicted extended continental shelf and maritime zones.
• Study underwater topography based on the combined bathymetric background image.
• Reference treaty-defined zones for legal or diplomatic research based on the map's annotations.
• Produce thematic maps for educational or planning purposes based on the official jurisdiction data.

Strengths

• Part of a standardized 27-map series (GeoCat 71789) from an official source.
• Based on the extended continental shelf boundaries approved by the UN Commission in April 2008.
• Background bathymetry is derived from two specific, cited sources (GA 2009 and Smith and Sandwell 1997).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
