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.

In tacheometry survey, an intercept of 0.755m was recorded on a staff which was believed to vertical, and the vertical angle measured on the theodolite was +15º. Actually, the staff which was 4 metres long was 0.14m out of plumb bob and leaning backwards away from the instrument position. Assuming it was an anallatic instrument with a multiplying constant of 100, what would have been the error in the computed horizontal distance?
Imagine that you are the engineer responsible for the tacheometric survey of an area where a public park will be built. While surveying, you found a cliff that needs to be detailed mapped. Using a tacheometer, the following readings were obtained:Data:Zenith angle (z): 45°Reading on stadimetric wires:High wire: 1.485 mMedium yarn: 1,000 mLow wire:0.948 mInstrument height: 1.50mHeight of observed point: 0 m Calculate the horizontal distance from the observed point and the height of the cliff in relation to the instrument position. ∆d = 100. (A-B). cos²z∆h = Dx tan(z)+ (hm+hi-hv)- Give preference to make the resolution editable, handwriting hinders understanding.

10 A theodolite was set up near the middle of the points "P" and "Q". If the height of the instrument is 1.20 m. The rod is sighted at point "P", vertical angle = +24 degrees, rod reading = 1.3 m, and stadia interval = 1.4 m. Then the rod is sighted at point "Q", vertical angle = +23 degrees, rod reading = 1.6 m, and stadia interval = 1.1 m. Taking K = 100, and C = 0. a) Horizontal Length from Point "P" and "Q" 210.045 m 216.829 m 219.837 m 225.013 m 213.560 m None of the Choices 222.570 m

An EDM slope distance AB is determined to be 561.276 m. The EDM instrument is 1.820 m above station A, and the prism is 1.986 m above station B. The EDM in- strument is mounted on a theodolite whose optical center is 1.720 m above the sta- tion. The theodolite was used to measure the vertical angle (+6°21'38') to a target on the prism pole; the target is 1.810 m above station B. Compute both the horizon- tal distance AB and the elevation of station B if the elevation of station A = 186.275 m.
