Introduction of levelling Survey

 A leveling survey! In surveying, a leveling survey typically involves measuring the difference in height between points. The dimensions of a leveling survey usually include:

- *Horizontal distance*: measuring the distance between points

- *Vertical angle*: measuring the angle between points

- *Height difference*: calculating the difference in elevation

There are different types of leveling surveys, including:

- *Differential leveling*: measuring height differences between points

- *Trigonometric leveling*: using angles and distances to calculate heights
