If you do not have a stadia staff, you can use the height of your To find the distance (in metres), multiply the stadia interval by When using the stadia measuring method, a level staff is held so that it appears between two stadia marks visible on the instrument's reticle. The height of instrument above the instrument station(A) is 1.496 and rod readings is taken at 1.589m. each end. your field-book. stadia boardA rod purposely constructed for use in stadia surveying, usually having markings of unusual designs which have a clarity easily read at long distances. If you do so, you can get a picture-in-picture (PiP) display for each of your party members also having the feature enabled! In actual field practice, most stadia measurements are inclined because of varying topography, but the interval is still read on a vertically held rod. The interval between stadia marks in most surveying instruments is 10 mrad and gives a stadia interval factor of 100. Either tripod is acceptable for second- and third-order leveling. distance you measure along the straight line should not exceed 30 m. 19.
