Levelling in Engineering Survey - Types, Methods, …
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 the vertical measurements & an …
What is levelling? - Surveying & Levelling
Levelling deals with measurements in a vertical plane. Level surface: A level surface is defined as a curved surface which at each point is perpendicular to the direction of gravity at the point. The surface of a still water is a truly level surface. Any surface parallel to the mean spheroidal surface of the earth is, therefore, a level surface. Level line: A level line is a line lying in a ...

Equipment for Differential Leveling Philadelphia Rod. Firstly, surveyors need a Philadelphia rod to conduct a survey. A Philadelphia rod is a level staff surveyors use in the field. It consists of two sliding sections with 1/100-foot increments. Surveyors can extend the rod from 7 ft to 13 ft when they need to take measurements that are higher. The tenths of a foot are indicated by black ...

Barometer is an instrument used to measure atmosphere at any altitude. So, in this method of leveling, atmospheric pressure at two different points is observed, based on which the vertical difference between two points is determined. It is a rough estimation and used rarely.
5 Main Sources of Error in Levelling | Surveying
If levelling is necessarily to be performed during wind , adequate arrangements should be made to shelter the instrument and larger readings should be avoided due to difficulty in holding the staff vertical. (iii) Sun: On hot sunny days, during the mid-day hours, the staff appears trembling near the ground and taking the correct readings becomes impossible. The work should therefore be ...

24.07.2015 · Simple leveling When the difference in the elevation of two nearby points is required then simple levelling is performed. Assume the elevation of BM Rock is known to be 820.00 ft. The BS at BM Rock is 8.42ft. So HI = (820 + 8.42)ft. Now the FS on “X” is 1.2ft. So the RL at “X” = HI – FS = 828.42ft Note that the RL of the instrument station will never comes in the calculation.
