Raised features on the Australian continental shelf and Lord Howe Island shelf derived and aggregated from Australian Hydrographic Service's (AHS) depth area features in the 1 degree S57 file series [for NESP D3]

Updated: 2025-08-14

Raised features were derived by aggregating and dissolving the boundaries of the 1 degree S57 file series for the Australian continental shelf and Lord Howe Island shelf (200 m) depicting depth area features. An algorithm was applied to the data that isolated these features from surrounding lower features or plains.
