2.Explain the term levelling.
Answers
Answer:
Levelling is a process of determining the height of one level relative to another. It is used in surveying to establish the elevation of a point relative to a datum, or to establish a point at a given elevation relative to a datum.
Answer:
The term levelling is explained below.
Explanation:
Leveling (or leveling) is a division of surveying whose purpose is i) to find the height of a particular point with respect to an assumed or assumed datum, and b) the point is at an assumed or assumed datum. The first is the work needed to design the work and the second is the work needed to start any civil engineering work. Leveling deals with measurements on vertical surfaces. A horizontal plane is defined as a curved surface that is perpendicular to the direction of gravity at any point. A still water surface is a truly horizontal surface. Therefore, all planes parallel to the average spheroid of the Earth are horizontal planes. This plane is perpendicular to the direction of gravity at all points indicated by the plumb line.
The surface of a still lake can be considered as an example of a horizontal plane.
Since the Earth is an inclined spheroid, the flat surface is not a plane, but a curved surface. All points of this plane are far from the center of the earth.
