AIM OF THE EXPERIMENT – Determination of height of 3 object whose bases are accessible�

• Theory- In plane surveying when the distance between the two points is not large then the distance between the points measured on a surface of the earth is called as horinzontal distances and the amount of correction due to curvature of earth surface is ignored.In this case we have to determine the height of three different objects by measuring the horinzontal between the base of the objects and instruments station.
• INSTRUMENT REQUIRED-1-Tacheometer (Digital/transit theodolite)

2-staff (telescopic staff/wooden staff)

3-tape-30m
