S1 and S2 are definitely the employees readings on B.M. from instrument positions at O1 and O2, respectively, and θ1 and θ2 will be the angles of elevation from O1 and O2, respectively.

It's the most often applied technique of leveling. In this technique, measurements are noticed directly from leveling instrument. Dependant on the observation details and instrument positions immediate leveling is divided into differing types as follows: Simple leveling

If the staff members is held within the reduced stage then the personnel looking at will be greater as well as reduced stage is a lot less. In the event the staff point is on the upper position then the staff members reading through is going to be smaller sized and the diminished amount is more.
