Marking Position of Station or Terminal Points in Survey

In surveying, it is essential to mark the position of station or terminal points accurately. To do so, surveyors use different types of instruments and tools. One of the commonly used tools to mark the position of station or terminal points is arrows. Let us discuss in detail:

Arrows

Arrows are used to mark the position of station or terminal points in surveying. They are made of wood or metal, and their length varies from 30 cm to 60 cm. Arrows are pointed at one end and have a flat head at the other end. They are usually painted with bright colors like red, yellow, or white to make them visible from a distance.

The following steps are involved in marking station or terminal points using arrows:

1. The surveyor selects the station or terminal point that needs to be marked.

2. The surveyor places the arrow vertically into the ground at the selected point.

3. The surveyor uses a plumb bob to ensure that the arrow is vertical.

4. The surveyor marks the position of the arrow on the ground using a peg or a wooden stake.

5. The surveyor records the position of the arrow in the field book.

Advantages of Using Arrows

The following are the advantages of using arrows to mark the position of station or terminal points in surveying:

1. Arrows are easy to use and handle.

2. They are visible from a distance.
