Match the type of levelling with its application.

Type of levelling Process

1. Simple levelling A. When the differential levelling is done in order to connect a benchmark to the starting point of the alignment of project

2. Differential levelling B. When the difference of level between two points is determined by setting the level instrument midway between two points

3. Fly levelling C. The process of taking levels transverse to the direction of longitudinal levelling

4. Cross-sectional levelling D. When the difference of elevation between the points is large and there are obstacles between the points

Answer 1

Explanation:

Simple levelling:

When the difference of level between two points is determined by setting the level instrument midway between two points.

Differential levelling:

When the difference of elevation between the points is large and there are obstacles between the points.

Fly levelling:

When the differential levelling is done in order to connect a benchmark to the starting point of the alignment of project.

Cross-sectional levelling:

The process of taking levels transverse to the direction of longitudinal levelling.
