A dumpy level is setup at one end of a line 120m long for the purpose of determining the instrument’s stadia interval factor. The line is marked by hubs at every 30m and a stadia rod were observed as follows: 0.308, 0.613, 0.918, and 1.222 meters respectively. The average value of the instruments stadia interval factor is?

Instruments for Surveying

Surveying is the practice that determines the relative three-dimensional positions of many different points on the earth’s surface. There are various instruments used in Surveying like Theodolites, Total station, Tripod stands, Plane table, etc. for measuring horizontal angle, vertical and sloping angle, which are very useful for giving accurate and precise measurement.
