TRIGONOMETRIC LEVELING. A vertical angle of -12°25’ is measured to the top of a water tank from an instrument set up on a hill 585.00 meters away from it. The telescope of the instrument is 1.45 m above the ground whose elevation is 462.73 m. Making due allowance for the earth’s curvature and atmospheric refraction, determine the elevation of the base of the water tank is the tank is 32.0 m high. with complete solution adn figure of the said problem
The following data were obtained by stadia observation: vertical angle, +12⁰30’; upper stadia hair reading and lower stadia hair readings, 4.500 and 3.250 m, respectively. The rod reading was taken at 3.875 m above the stadia point at A and the height of instrument above the instrument station, B, is 1.620 m. The stadia interval factor is 99.5 and the instrument constant is 0.381 m. Compute the difference in elevation between the two ground points. (Type your answer using 3 decimal places, numerical value only, no need to include the units)
The upper and lower stadia hair readings on a stadia rod held at station B were observed as 3.50 and 1.00 m, respectively, with the use of a transit with an internal focusing telescope and having a stadia interval factor of 99.5. The height of the instrument above station A is 1.45 m, and the rod reading is taken at 2.25 m.
