Abstract

Spirit levelling is a complex geodetic measurement that combines several elementary steps, already defined in Sect. 4.6 (see also Fig. 4.6), each of them providing a step increment on a short baseline; such increments are then added along a levelling line, joining two stations \(\text {P}\) and \(\text {Q}\). In this way, recalling (4.56), we have a measurement related to the extremes \(\text {P}\) and \(\text {Q}\) and to the path connecting them.
