#### Types of Measurements in Surveying

Surveying is the art of making suitable measurements in horizontal or vertical planes. This is one of the important subjects of civil engineering. Without taking a survey of the plot where the construction is to be carried out, the work cannot begin.

#### From the above definition, we conclude on two types of measurements in surveying. They are as follows:

- Linear measurements
- Angular measurements

Now we will go on with the discussion of each of these types of measurements along with their subtypes.

#### Linear measurements are further classified as follows:

Horizontal Distance

Vertical Distance

#### Horizontal Distance

A horizontal distance is measured in horizontal plane if a distance is measured along a slope, it is reduced to its horizontal equivalent.

#### Vertical Distance

A vertical distance is measured along the direction of gravity at that point. The vertical distance are measured to determine difference in elevations in various points.
