Do you want to know about levelling staff & to learn the procedure of taking staff reading
If yes, then you are at right place Here you'll know it all. All divisions are marked with black on a white background The purpose of a level is to establish a horizontal line of sight the purpose of the leveling staff is to determine the amount by which the station is above or below the line of sight leveling staves may be divided into two classes
This is obtained by adding the bs reading to the rl of the bm or cp on which the staff reading was taken The operation of setting the eyepiece & the object glass a proper distance apart for clear vision of the object is known as focusing This is done by turning the focusing screw clockwise or anticlockwise. The smallest division on the staff determines its least count.
The lower end of the rod is shod with metal to protect it from wear and usually point of zero measurements from which the graduations are numbered
The least count of a leveling staff is 5. Surveying of an area by chain and compass survey (closed traverse) & plotting aim To survey an open field by chain survey in order to calculate the area of the given field
