The equation D = Ks + C is employed in computing the horizontal distances from stadia intervals when sights are horizontal, the stadia constant C is the distance from the center of the instrument to the principal focus. Stadia Definitions for Land Surveyors 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.
Staff intercept is found by subtracting the reading of the upper and lower stadia reading. The length intercepted on the stadia rod is 1.8 m and the line of sight makes an angle of 4 30' with the horizontal. The constant k = f/i is called the multiplying constant or stadia interval factor and the constant (f + d) =C is known as the additive constant of the tacheometer but the latter one is made zero by using an anallatic lens in the instrument.

Sample problem Compute the average value of the stadia interval factor. pXM distance may also be computed by extracting the root of the sum of the square of HD Weatherstreet Wisconsin, The telescope of most surveying instrument are equipped with stadia hairs in addition to the regular interval and horizontal hairs. THEORY The ratio between the focal length and the spacing between the two cross hairs of the transit (f / i ) is called the stadia interval factor and is designated by the letter K. For any given instrument, this value remains constant and the nominal value is usually 100. problem1 (2points) a transit with a stadia interval factor of 99.98 was set at c on the line between points a and b, the following stadia readings were observed.

WebIf the stadia intercept was 1.25m and the stadia interval factor of the instrument used is 100, determine the horizontal distance from the transit to the rod and the difference in elevation between the point over which the transit was set up and the point on which the rod was held. Other forms of tacheometry in surveying include the use of stadia rods with theodolites or plane-table alidades. This process (+) for angle of The discussion requires a minimum of 250 words. Additive constant or stadia constant calculator uses Stadia constant = ( Focal length of telescope + Distance ) to calculate the Stadia constant, The Additive constant or stadia constant formula is defined as a fixed, integer ratio between the difference of the rod readings and the distance from the telescope to the rod. is wrapping a car illegal near manchester.

Site: UST Field / level and clear ground. If one observes a vertical length on a stadia rod, rule or levelling rod with the telescope and sees that the rod spans 0.500m between the marks (the stadia interval), then the horizontal distance from the instrument to the rod is: In the adjacent image, the upper stadia mark is at 1.500m and the lower at 1.345m. The difference is 0.155m. Thus the distance from the instrument to the levelling rod is: Language links are at the top of the page across from the title.
