Australia's Maritime Jurisdiction Map for Cocos and Christmas Islands

Geoscience Australia Data provides a map depicting Australia's maritime jurisdiction around the Cocos (Keeling) Islands and Christmas Island. The map is part of a 27-map series and shows the extended continental shelf approved in 2008, treaties, and maritime zones over a bathymetric background. It is available as an A0-sized PDF downloadable from the web.

Use Cases

• Analyze maritime boundary claims based on the depicted extended continental shelf and treaty lines.
• Study ocean floor topography for the region based on the combined bathymetric background image.
• Reference jurisdictional zones for legal or environmental planning based on the map's maritime zone delineations.

Strengths

• Part of a standardized 27-map series (GeoCat 71789), suggesting consistent methodology.
• Background bathymetry is derived from two specific, cited sources: a 2009 9 arc-second grid and Smith and Sandwell, 1997.
• Depicts multiple legal and geographic features including the 2008-approved continental shelf, treaties, and maritime zones.

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.
• Data is provided as a static PDF and HTML, limiting direct machine-readability and analysis.
