      Block levelling is the indirect method of levelling of contours. This method is used for a small survey area. The area to be surveyed is divided into a number of squares or blocks and the size of each block varies from 5 m to 20 m depending upon the nature of the contour or contour interval. The Reduced Level (RL) of corners of a square block is determined by means of a level and a staff.

      Block levelling in surveying is a method of identifying elevation changes between two points. It involves the use of an optical level, which is used to establish an elevation baseline across a series of points. From this baseline, the level is then used to correct for any changes in the elevation over a given distance.

      This technique is particularly useful when doing topographic surveys or other precision measurements that are affected by minute changes in elevation.
