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

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, along with treaties and various maritime zones. It is produced by Geoscience Australia and uses a background bathymetric image derived from a 2009 9 arc second grid and a 1997 grid by Smith and Sandwell.

Use Cases

• Visualizing maritime boundaries and zones based on the described treaties and legal approvals.
• Analyzing bathymetric data for the region based on the combined 2009 and 1997 background grids.
• Referencing the approved 2008 extended continental shelf limits for legal or research purposes.
• Incorporating the map as a base layer for regional marine spatial planning.

Strengths

• Part of a standardized series of 27 maps providing consistent jurisdictional coverage.
• Based on an officially approved continental shelf boundary from April 2008.
• Background bathymetry combines a detailed 2009 9 arc second grid with an earlier 1997 source.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
• The primary data format is a static A0-sized PDF, limiting direct machine-readability.
