Maritime Jurisdiction Map of Heard and McDonald Islands

Australia's maritime jurisdiction around the Heard Island and McDonald Islands region, including a portion of the Australian Antarctic Territory. This map is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789), published by the Australian Ocean Data Network. It depicts maritime zones and the extended continental shelf approved in April 2008.

Use Cases

• Analyze the extent of Australia's extended continental shelf boundaries approved by the CLCS in 2008.
• Study maritime zone delineations, including Exclusive Economic Zones, around Heard and McDonald Islands.
• Use the background bathymetric grid from Smith and Sandwell (1997) for seafloor topography analysis.
• Reference the Blue Marble land imagery from NASA for contextual land features.

Strengths

• Part of a standardized series of 27 constituent maps for consistent national coverage.
• Based on authoritative sources including CLCS approvals and treaties.
• Integrates bathymetric data from a published grid (Smith and Sandwell, 1997).

Limitations

• Data is static, representing a single approved snapshot from 2008.
• Available only as an A0-sized PDF, limiting direct geospatial analysis.
• No underlying tabular or vector data provided for individual maritime zone features.
