24 Ιουλ 2015 · Levelling is the branch of surveying that deals with determining elevations and measuring vertical distances. It is important for engineering projects to establish accurate networks of heights. The key principle is obtaining a horizontal line of sight to measure vertical distances of points above or below this line.
This unit develops the understanding and skills required to perform surveying calculations. It is intended that the procedures outlined in the specification are performed using semi-manual methods and learners will also gain an understanding of the software available for site surveying.
Y level or Wye-level consists y-shaped frames which supports the telescope. Telescope cane be removed from the y-shaped supports by releasing clamp screws provided. These y-shaped frames are arranged to vertical spindle which helps to cause the rotation of telescope.
