geodetic leveling
Spirit leveling (device or level for determining a true horizontal or vertical reference point) of a high order of accuracy, usually extended over large areas, to furnish accurate vertical control in the vertical dimension for all surveying and mapping operations.

The leveling follows the geoid and its associated irregular level surfaces rather than any mathematically determined spheroid or ellipsoid and associated regular level surfaces.
