    23/01/2017· Levelling is the most widely used method of obtaining the elevations of ground points relative to a reference datum and is usually carried out as a separate procedure to those used in fixing planimetric position The basic concept of leveling involves the measurement of vertical distance relative to a horizontal line of sight Hence it requires a graduated staff for theLeveling Surveying Procedure The following three methods are mostly found for finding out the variations in elevation: 1 Barometric leveling 2 Trigonometric leveling and 3 Spirit leveling Barometric leveling: Barometric leveling is based on the perception that variation in elevation among two points is reciprocal to the variation inLeveling Surveying Procedure | Leveling Surveying Equipment31/08/2020· Levelling in surveying Designing Buildings Share your construction industry knowledge Levelling is a process of determining the height of one level relative to another It is used in surveying to establish the elevation of a point relative to a datum, or to establish a point at a given elevation relative to a datumLevelling in surveying Designing Buildings
