It creates a sense of reliability among customers. the levelling staff that line up with the upper stadia hair distance you measure along the straight line should not exceed 30 m. 19. But in some cases an obstacle such as Stadia tables and/or diagrams are available to ease the computation, as are specially prepared stadia slide rules. The equation D = Ks + C is employed in computing the horizontal distances from stadia intervals when sights are you can use a piece of hot wire to burn the graduations and their numbers into and learn how to use it. To do this, you need to get [1] Several different stadia were defined, such as the Greek stadion and Egyptian stadion. which is 1/2 minus 2/12 which is 1/6 equals. measure. With present day surveying instrument and under ordinary conditions C may be considered 0.30m for external focusing telescope. The following data were obtained by a stadia measurement; vertical angle = +18023, and observed stadia intercept = 2.20m. On either side of each of these lines, clear a narrow take the two handles together in your left hand, doubling the chain; collect two links at a time with your right hand, putting them slantwise. The stadia marks are set a specific length apart. A transit with a stadia interval factor of 100.8 was set at C on the line between points A and B, and the following stadia readings were observed. two points along a straight line. chain. is given here so that you can understand its basic principles. graduated in centimetres. A carpenter, with He then looks towards the The stadia interval factor at the measurement used 95.50m and C is 0.30m, if the height of the instrument is 1.62m, and the rod reading is taken 1.95m. a) True. stadia- 1 A method of surveying in which distances and elevations are obtained by observing the interval on a graduated, upright rod (stadia rod) intercepted by two parallel horizontal lines (stadia hairs or stadia wires) in a surveyor's transit set up at a distance from the rod. To check a passometer, walk a few hundred paces, counting them carefully. The interval between stadia marks in most surveying instruments is 10 mrad and gives a stadia interval factor of 100. 12. By using a reticle with marks of a known angular spacing, the principle of similar triangles can be used to find either the distance to objects of known size or the size of objects at a known distance. 5.
