So, to get the measurement over the ground, you have to multiply the difference in the stadia hair readings by 100 if the reading difference is 1cm, that represents 1m. In the auto level machine, the difference in the stadia hair reading is set at the 1: 100 ratio. So, we can say The horizontal distance is 33 meter. In Autolevel machine, the scale of the difference of Upper Stadia and Lower Stadia is designed in such a manner i.e, Now convert the 0.33 meter into cm i.e, 0.33 x 100 = 33 cm. Now Difference between Upper Stadia and Lower Stadia = 1.56 – 1.23 = 0.33 meter Take the 2 readings of the staff at the upper & lower stadia hair level as shown below. Focus the telescope over the leveling staff, positioned over point B.ħ. As you can observe in the above drawing, the telescope consists of two stadia hairs i.e. Adjust the telescope lens until you observe the cross-hair & stadia hair clearly. Transfer the auto-level position over the ground by plumb bob & let us name it point A.ĥ. Level the auto level machine by centering the bubble in a vial.ģ. Set up the tripod legs & fix the auto level to the tripod.Ģ. The horizontal line and vertical line cross perpendicular to each other provide on the auto level is called crosshair. You can see in the figure below: Crosshair: Calculate Horizontal Distance using Auto Level Stadia’s hair is two lines one above and one below from the center crosshair. It is the horizontal cross-hair in the Auto Level in equal distance from the center crosshair of the Auto level. Followings are the terminology used in the auto-level survey. So let’s do it:īefore Calculate Horizontal Distance using Auto Level and staff, you need to know some terminology used in the auto level survey. I am also happy to share this knowledge with you. I hope you are much excited to see this topic today. But today I will provide you the details of calculating the horizontal distance between auto-level machines to staff. It is made of wooden and aluminum rods use to determine vertical distance and horizontal distance with the help of an Auto level machine. Staff is the leveling rod used in surveying. It is additionally used to quantify even distances nearby. The distance is measure with the help of staff.Īn auto-level machine is an expert device ordinarily utilized for an exact evening out. It is the automatic level machine used to measure distance, finding accurate points and elevation of the land, buildings, and any structures. How to Calculate Horizontal Distance using Auto Level in 2021 What is Auto level machine ? | Level Focus the auto level machine on the level staff, read the measurements of both cross and stadia hair markings. To measure horizontal distance with the Stadia measuring method, hold the staff rod so that it can be seen between the two stadia marks on the instrument’s reticle. The discovery of the Stadia range is good for finding topographical details such as rivers, fields, bridges, roads and buildings. The tool must be used on a level surface to make this method work correctly.
