 In this blog, we discuss . what is levelling in the survey, the types of leveling, and the purpose of leveling. Leveling in survey Leveling:-                        ·         Leveling is the process of determining the horizontal and vertical positions of points on a plane.                            ·          Leveling is measuring the slope or height of a surface, whether in horizontal or vertical directions. Horizontal leveling is accomplished mainly by means of levels, while vertical leveling uses a total station Types of leveling:-  There are two types of leveling:-        Horizontal leveling, which measures the slope of a surface, and Vertical leveling, which measures the height of an object. The most common kind of leveling is horizontal leveling, which can be done with either transit or a total electronic station. Purpose of leveling:- ·         It is used in surveying to establish a high degree of accuracy in map-making and construction projects. ·         Leveling is u

 In this blog, we will discuss what is theodolite , the types of theodolite, fundamental lines  of theodolite, uses of theodolite in detail.             Basic information about theodolite 1.         What is   theodolite?                Theodolite is a precision optical   instrument that is used to measure horizontal and vertical angles. Its accuracy depends upon its least count. 2.         What are the types of theodolite? There are two types of theodolite ·          Transit Theodolite. ·          Non-transit Theodolite.     3.         Differentiate between transit and non-transit theodolite? Transit:-           That type of theodolite whose telescope can rotate 180 degrees in the vertical a plane is called transit theodolite. Non-transit:-                      That type of theodolite whose telescope can rotate 360 degrees in the vertical plane is called a  non-transit theodolite. 4.        State the type of theodolite . According to observing reading?
