What is a peg test used for in surveying?

Calculating area

Checking levelness and line of sight

A peg test is employed in surveying primarily to check levelness and line of sight. This technique involves placing pegs or markers at specific intervals in the field. By establishing a line of sight from one peg to another, surveyors can determine if the ground is level or if there are any variations in elevation along that line. This is particularly useful for ensuring that structures are built on level ground, as well as for creating accurate horizontal and vertical control in a survey.

The process of checking line of sight also enables surveyors to assess potential obstructions that may affect visibility or influence measurements. Hence, it is a crucial aspect in the preparation for more detailed surveying tasks.
