Scope: Hydrography, drilling.
Remarks: Approximate because not specific to any location or epoch. Users are advised to not use this generic CRS but instead use one with a specific datum origin (e.g. "Mean Sea Level at xxx during yyyy-yyyy") or defined through a specified geoid/hydroid model.
Area of use: World.
Coordinate system: Vertical CS. Axis: height (H). Orientation: up. UoM: m.
