levelling
Levelling or leveling (American English; see spelling differences) is a branch of surveying, the object of which is to establish or verify or measure the height of specified points relative to a datum. It is widely used in geodesy and cartography to measure geodetic height, and in construction to measure height differences of construction artifacts.
It is also known as spirit levelling and differential levelling.

UK SC Render and levelling with Cement-based Adhesive
