Stadia rod surveying

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. Also called stadia survey. See also tachymetry, tacheometry. 2 In ancient Greece and Rome, a unit of linear. Transit or theodolite with stadia hairs and tripod Philadelphia leveling rod Field book No. 3 drafting pencil INTRODUCTION When distances between traverse stations are determined by the stadia method, the resulting survey is called a stadia traverse. The stadia method, referred to as tacheometry in Europe, is There are two common methods of surveying to determine slope distance. The traditional method involves stadia, where the difference in rod readings at the upper and lower stadia hairs are converted to a slope distance. The newer method uses a total-station instrument and prism pole to determine the slope distance electronically

horizontal hairs, called stadia hairs, and a survey rod. Self-leveling levels and transits have stadia hairs. One of the stadia hairs is above the center horizontal cross hair and the other is an equal distance below it. To take a stadia measurement, observe through the telescope the interval in meters or fee two short horizontal lines, one above and one below the horizontal crosshair. These lines are termed Stadia Lines or Stadia Hairs. When used with an Engineering Grade Rod, the distance from the instrument to the rod can be determined quickly by subtracting the bottom stadia reading from the top reading and multiplying the difference by 100 Person 2 (P2) aim level at stadia rod. A. Look through level and find stadia rod, focus view field until you can clearly read rod. B. Read elevation at which crosshairs in level cross the stadia rod. Crosshairs can be adjusted using knob on side of level C. Record this elevation as the starting backsite (B.S.) 3. P1 hold stadia rod on survey. Most surveying Instruments have a Stadia constant of 100. Therefore, if 6 feet is indicated on the rod, then the distance from the telescope to the rod is 600 ft. The calculation would look like this 100 * 6 ft = 600 ft. Stadia can give results accurate to about 1 foot under ideal conditions Surveying Rods (including grade rods, Lenker rods, and leveling rods) are useful accompaniments to construction and surveying tools for taking measurements and determining elevations. Leveling rods may also be called laser poles. For maximum efficiency and accuracy, grade rods are commonly used with other leveling instruments, such as laser.

Remember, grade rods are also known as leveling rods or builders rods , and are not only used by land surveyors. Most of the time, grade rods are used by contractors that build many different things but mostly including concrete work, paving asphalt, installing concrete floors, driveways and foundations, trenching and piping gravity utilities like sanitary sewer and storm drains, as well. Old time surveyor with stadia rod transit and tape. From colonial times, though the 1800's, surveying in this country was performed using a crude transit or a compass and a chain. The most common surveyor's chain was 66 feet long and made up of 100 links. 1 link is equal to 1/100 of a chain or 7.92 inches Stadiametric rangefinding, or the stadia method, is a technique of measuring distances with a telescopic instrument.The term stadia comes from a Greek unit of length Stadion (equal to 600 Greek feet, pous) which was the typical length of a sports stadium of the time.Stadiametric rangefinding is used for surveying and in the telescopic sights of firearms, artillery pieces, or tank guns, as well. Stadia rod definition is - a graduated rod used with an instrument having stadia hairs to measure the distance from the observation point to the place where the rod is positioned by observation of the length of rod subtended by the distance between the stadia hairs when these are fixed or of the space between the stadia hairs when they are adjusted to cover a certain definite interval on the rod Usage. Stadia marks on a crosshair while viewing a metric levelling rod. The top mark is at 1.500 m and the lower is at 1.345 m. The difference between the rod readings is 0.155 m, yielding a distance to the rod of 15.5 m. A typical surveyor's instrument reticle has two pairs of stadia marks. One pair are on the horizontal centreline and the.

With the Stadia Surveying Instrument focused on the rod, read the measurement markings on the stadia rod shown between the two stadia markings. The formula to calculate distance is D=R*S (Distance = Rod Reading Multiplied by the Stadia Constant.) Most surveying Instruments have a Stadia constant of 100 Definition: A long, brightly colored rod with calibrations for obtaining elevations with a surveying instrument. Stadia is a surveying method for determination of distances and differences of elevation by means of this telescopic instrument having two horizontal lines through which the marks on a graduated rod are observed

The stadia hair system; The tangential system; 1) Stadia hair system . The stadia hair system may further be divided into two types: Fixed hair method; In this method, stadia hairs are kept at a fixed interval and the intercept on the leveling staff ( or stadia rod) varies, depending upon the horizontal distance between the instrument station. This video shows you how to measure distance using the Stadia Lines in an Automatic Level. The measurements are calculated in metres Features of Tacheometer. A transit theodolite fitted with special stadia diaphragm is known as tacheometer. It is the main instrument of tacheometric surveying. Its telescope contains two horizontal hairs called stadia hairs in addition to the regular crosshairs. The stadia hairs are equidistant from the central cross-hairs and they are.

called stadia hairs in addition to the regular crosshairs. The stadia hairs are equidistant from the central cross-hairs and they are specially termed as stadia lines or stadia webs. ii.

Stadia marks often have a scale of 100:1, meaning 0.5 meters between these stadia marks represents a distance of 50 meters to the target. Both a manual level and an automatic level allow the user to make rough adjustments by moving the level's components until the bubble level or circular level is in alignment Effectively used in hydrographic surveying. It is used in location surveys for roads, railways, reservoirs, etc. Also, used to test more accurate measurements. Principle of Tacheometry: The principle of tachometry is to enable horizontal and vertical distances to be computed from readings on a stadia rod and thus eliminate the chaining operation To determine the stadia interval factor, a theodolite is set up at a distance C back of the zero end of a level base line 240.0 m long, the base line being marked by stakes set every 30.00 m. A rod then is held at successive stations along the base line For long sights, special staff called stadia rod is generally used. The graduations are in bold type (face about 50 mm to 150 mm wide and 15 mm to 60 mm thick) and the stadia rod is 3 m to 5 m long. To keep the staff or stadia rod vertical, a small circular spirit level is fitted on its backside. It is hinged to fold up. 12

In tachometric surveying, instrument used is known as a tachometer. With the help of a tachometer observations (stadia readings and vertical angles) are taken and horizontal and vertical distances are determined by using formulae. Before doing calculations we should known the values of two constants for a tachometer to be used for survey work. Stadia lines The stadia lines on the reticle can be used for simple distance measurement. The distances intercepted on the vertically-held rod between two stadia hairs seen in the eyepiece gives the distance. Just multiply the difference on the rod between the top and bottom stadia lines by 100* as shown in the figure below Stadia rods generally are 10 to 15 feet long, 3 to 5 inches wide, and about 3/4 inch thick. They may be made in one piece or in sections for ease in carrying them. Some stadia rods are flexible and maybe rolled up when not in use. Flexible rods are merely graduated oilcloth ribbons, tacked to a board. Some examples of stadia rods are shown in.

The stadia method of measuring distance, a rapid system useful in surveying inaccessible terrain and in checking more precise measurements, consists in observing through a telescope equipped with two horizontal cross hairs or wires (stadia hairs) the interval delimited by the hairs on a calibrated stadia rod; the interval depends on the. Page 1 of 12 Plane Surveying - Stadia Civil Engineering 235 Department of Civil Engineering, UBC The distance on the rod AB = I is called rod intercept or stadia interval, while the distance ab = i is the spacing between stadia hairs Surveying: Theory and Practice: James Anderson To determine the stadia interval factor, a theodolite is set up at a distance C back of the zero end of a level base line 240.0 m long, the base line being marked by stakes set every 30.00 m. A rod then is held at successive stations along the base line Lower Stadia Reading = 5.20 ft . Rod Intercept = 0.10 ft. Using the stadia readings, you can estimate the distance between the instrument and the rod. First find the rod intercept by subtracting the lower stadia reading from the upper stadia reading. Then multiply the rod intercept by the stadia multiplier (usually 100) 4.5 inch Transit, David White. Description: For the mechanically-minded, non-powered types: not electronic -- no batteries -- completely opto-mechanical. Takes patience and practice, but you can get accuracy to minutes of horizontal and vertical angle. Use with stadia rod; read stadia for distance, or use survey tape for distance
