Arrows in Surveying

Arrows in Surveying | Uses, Advantages & Materials Used in Arrows | 6 Differences Between Arrows and Pegs


Arrows in surveying are the marking pins that are mostly used in the chain surveying. They are used to mark the end of the chain length; if the length of the line to be measured is more than a chain length. After the end of each chain length, the arrow is inserted in the ground, but if the ground is hard and difficult, a scratch may be made with the pointed end of the arrow.

They are 4 mm in diameter and have a minimum tensile strength of 700 N/mm². Length of arrows varies between 250-500mm. As per IS 1842, the overall length of arrows is 400mm with 50 mm diameter loop.

The white or red tape is tied to the ring of the arrows to increase the visibility of arrows.




  1.1. Materials used for making arrows in surveying:  

Arrows are made up of good quality hardened and tempered steel wire and these wires are enamelled ( mostly with black enamel).


  1.2. Uses of arrows in surveying:  

i. It is used in many surveying sectors to mark the boundaries and points.

ii. It is generally used in chain surveying to mark the end of the chain length.


  1.3. Advantages of arrows in surveying:  

i. It helps to locate the point in the ground while surveying in a large field.

ii. It is lightweight and easy to handle.

iii. It is suitable to use in any weather conditions.


  1.4. Difference between arrows and pegs  

Pegs are generally made up of wood. They are also used to locate points in the ground.  Some differences between pegs and arrows are:

1They are made up of steel.They are mostly made up of wood.
2They have one end pointed and another end bent into a loop.They have one end tapered.
3The standard length of arrows is 250 mm to 400mm.The standard length of pegs is 150mm.
4They are 4mm in diameter.They have sides of 25 mm to 30 mm.
5They are mostly used in chain surveying.They are used in all type of surveying.
6They used to mark the end of the chain length.They used to mark the endpoint of the survey line.
