If the benchmark is a long length with the get the job done station, fly leveling is applied. In this type of circumstance, A brief bench mark is ready up for the workstation determined by the first benchmark. Though It's not extremely specific, it is applied to determine approximate stages.

It is basically a technique that is certainly made use of to check a series of amounts or readings that have taken Earlier. At the conclusion of every single day do the job Alright a line of level starting from the point and returning to the starting point is checked.
