# Lab 4
The basic idea of this lab is to determine elevation at a specific station using a systematic method. We have 5 stations in total (4 stations and a benchmark). The elevation of the benchmark is already given to us. Try to work counter-clock wise as it makes it easier to determine the backlight and foresight. Place the level in the direction as if you’re movingg counter clock wise around the stations. When you turn the level towards the benchmark, you are calculating what’s called a backsight. It’s opposite to the direction you’re moving hence it’s called backsight.

Getting that backsight from the level will allow us to add that number to the elevation that was already given. When we add the backlight to the elevation, we get the height of the instrument from the deep ground. Then, we turn our level to our direction (counterclockwise) and get the foresight of the next station. In order to find the elevation of the next station, we simply subtract the foresight from the height of the instrument. We continue this process for all station until we get back to the becnchmark. When we subtract the foresight of the benchmark from the foresight in the final stop, we should get the given elevation that was already provided.
