How to Distribute Error In Levelling Computation

NB: It is important to note that every instrument set up has equal amount of correction. Determination of Levelling Misclosure || Levelling Computation    • Determination of Levelling Misclosure | Le...   Levelling is the process of determining the change in elevation between points. It is a 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 datum. Height of Collimation Method It consists of determining the elevation of the plane of collimation (H.I.) for every set up of the instrument and to obtain the reduced level of point to with reference to the respective plane of collimation. In other words, we determine the reduced level of points by making reference to the height of instrument set up. Rise and Fall Method It consists of determining the difference of elevation between consecutive points by comparing each point after the first that immediately preceding it in the direction of travel. How to Distribute Error In Levelling Computation On this video we explained how to distribute the misclosure gotten from the levelling computation.
