Control Survey and Geodetic reductions

Control surveys or survey controls are used to establish reference points as a basis for various construction activities. Vertical and horizontal control points are to be established in a control survey to increase accuracy. After establishing the control points, all other types of surveys such as topographic, right-of-way, aerial mapping, construction layout, boundary surveys, and utility mapping can be worked upon so that control networks can be formed. The place from which the observations are made is called a survey station.

Read the question carefully and give me complete right solution according to the question. Thank you. A stadia reading is recorded to have an upper cross hair reading of 1.655 m and a lower cross hair reading of 1.510 m. The zenith angle is 82º 45’ 10” and the height of instrument is recorded as 1.450 m. Calculate the horizontal distance between the instrument and the staff position and the RL of the ground surface at the staff position, if the RL at the instrument location is 50.345 m at ground level.
Engineer’s Transit was set at a horizontal distance of 175.24 meters from the base of a tower. The angle reads 280 45’ at the top of the tower. If the backsight reading from a reference benchmark of elevation 30.00 meters above mean sea level is 1.68 meters, find the elevation of the top of tower.
A level was set up in the middle of two pegs A and B and the staff readings were 2.015 and 1.895 respectively. The instrument was then set up at B and the readings on A and B were 2.195 and 2.005 respectively. What is the error in the line of collimation and reading on peg A which makes the line of collimation horizontal?
Please calculate the Angle (deg-min-sec) of STUDENT 1 and 2. Thank you!
Show complete solution and answer in the nearest 4 decimal places. An engineer's transit is setup at point B which has an elevation of 145.65m above MSL. Point B issituated between points A and C. Point B is the lowest among the three points. The horizontal distance BA and BC are 180m and 200m respectively. The rod reading at A is 1.50m with the line of sight inclined 15 degrees with the horizontal. The rod reading at C is 1.95m with the line of sight inclined 35 degrees with the horizontal. The height of the instrument/transit is 1.10m from the ground. a) What is the difference in elevation of point A and C? b) What is the elevation of point €?
Locate the centroid y̅ of the shaded area.
The following staff readings were observed successively with a level. The instrument has been shifted after the second and fifth reading: 0.675, 1.230, 0.750, 2.565, 2.225, 1.935, 1.835, 3.220. The first reading was with staff held on benchmark of RL 100.000 m. Enter the readings in a page of level book and calculate the RL of all points. Apply arithmetic checks. Use plane of collimation method.
A backsight is taken on a benchmark of elevation 500 m, rod reading of 1.50 meters,vertical angle of – 30° 25’, and horizontal distance from instrument of 75.6 m. A foresightis taken on a point A with rod reading of 0.80 m., vertical angle of + 20° 15’, and a slopedistance of 40.50 m from the instrument. If the height of instrument is 1.20 m. and theinstrument is situated along the line between BM and point A, determine the elevation ofpoint A and the grade from BM to point A disregarding the effect of curvature andrefraction.
In the two-peg of a dummy level, the following observation are taken. Rod Reading on A Rod Reading on B INSTRUMENT SET UP NEAR A 3.463 0.821 INSTRUMENT SET UP NEAR B 4.125 1.307 What is the difference in elevation between A and B? If the line of sight is not in adjustment, determine the correct rod reading on A with the instrument still set up at B. If the line of sight is not in adjustment, determine the correct rod reading on B with the instrument still set up at A.
The staff readings 9.01, 6.62, 5.15, 2.12, 0.98, 10.68, 12.45, 9.75 were observed with a dumpy level. The level was shifted after the second, fourth, and sixth readings. The first reading was taken on a bench mark of R.L. of 355.50 ft. Calculate the reduced level of change points, and the difference of level between the first and last point by the height of plane of collimation method. Apply the usual checks.
