Maritime Jurisdiction Map of Heard and McDonald Islands with Bathymetry

Australia's Maritime Jurisdiction around Heard Island and McDonald Islands is depicted in a geospatial map using a Mercator projection. The map is part of the 27-constituent 'Australia's Maritime Jurisdiction Map Series' and shows the extended continental shelf approved in April 2008, treaties, and various maritime zones. Background imagery includes bathymetric data from Smith and Sandwell (1997) and land imagery from NASA's Blue Marble.

Use Cases

• Analyze maritime boundary definitions based on depicted treaties and zones.
• Study bathymetric features of the seabed based on the Smith and Sandwell grid background.
• Reference continental shelf limits based on the 2008 Commission approval.
• Produce derivative maps for regional governance based on the A0-sized PDF source.

Strengths

• Includes bathymetric background derived from a specific 1997 grid by Smith and Sandwell.
• Part of a standardized 27-map series (GeoCat 71789) ensuring consistent thematic coverage.
• Based on authoritative maritime limits approved by the Commission on the Limits of the Continental Shelf in April 2008.

Limitations

• Data format is primarily PDF and HTML, which may limit direct machine-readability for analysis.
• Row count and column-level documentation are absent; data structure must be inferred from the visual map.
• Freshness should be verified; the last metadata update is 2026-04-10, but the underlying bathymetric data is from 1997.
