Question

Levelling used in hilly areas which type?

Answer 1

Answer:

Explanation:

Tacheometer principle is used to determine the elevation of points. Line of sight is inclined and it is more suitable for surveying in hilly terrains.

Answer 2

Answer:

Stadia Leveling is used in hilly areas.

Explanation:

Many types of levelling are used in surveying for the measurement of the level difference of different points with a fixed point. This is useful in various civil engineering construction works where it maintains the levels of different structures.

There are many types of levelling in which Stadia Leveling is one of them.

Stadia Leveling is a modified form of trigonometric levelling. Tacheometer principle is used to determine the elevation of points in this levelling. In this case, the line of sight is inclined from the horizontal. For surveying in hilly terrains, this levelling is more accurate and suitable.

Hence, the correct answer is Stadia Leveling.
