Australia's Maritime Jurisdiction Map North of 25°S, Including Extended Continental Shelf

A geospatial map depicting Australia's maritime jurisdiction north of approximately 25°S. It is one of 28 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789) and shows areas including the Cocos (Keeling) Islands, west of Christmas Island, and the northern continental region. The map incorporates the extended continental shelf approved in April 2008, treaty boundaries, and various maritime zones over a background of combined bathymetric and topographic imagery.

Use Cases

• Analyze maritime boundaries and jurisdiction based on depicted treaties and zones.
• Study the extent of Australia's continental shelf based on the 2008 Commission approval.
• Incorporate bathymetric reference data based on the combined Geoscience Australia and Smith/Sandwell grid.

Strengths

• Map is part of a standardized series of 28 constituent maps, suggesting systematic coverage.
• Background bathymetry is derived from specific, cited sources: the 2009 9 arc second grid and the 1997 Smith and Sandwell grid.
• The map depicts legally significant boundaries, including the extended continental shelf approved by the Commission on the Limits of the Continental Shelf in April 2008.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided as a static PDF/HTML map; underlying vector/raster data for analysis is not specified.
• Row count is unknown, which may limit suitability assessment for quantitative geospatial analysis.
