Australia's Maritime Jurisdiction Map for Southwestern Western Australia

Southwestern Western Australia's maritime jurisdiction is depicted in this map, part of a 27-map series. It shows the extended continental shelf approved in April 2008 and various maritime zones, with a background bathymetric image derived from 2009 and 1997 grids. The map is provided as an A0-sized PDF by the Australian Ocean Data Network.

Use Cases

• Analyze maritime zone boundaries based on the depicted extended continental shelf and jurisdictional lines.
• Study seafloor topography based on the combined bathymetric background imagery from 2009 and 1997.
• Reference jurisdictional claims for legal or policy work based on the officially approved continental shelf limits.

Strengths

• Part of a standardized 27-map series (GeoCat 71789) for consistent coverage.
• Based on an extended continental shelf formally approved by the Commission on the Limits of the Continental Shelf in April 2008.
• Background bathymetry combines a 2009 9 arc-second grid with a 1997 grid by Smith and Sandwell.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au.
