Surveying (CE-303) - Important Questions

Define surveying and explain the types/classification of surveying. Discuss the fundamental principles of surveying.

Explain the elements and notations of a simple circular curve with a neat sketch.

The following staff readings were observed successively with a level, the instrument having been moved after third, sixth and eighth readings. The first reading was taken on a B.M. of R.L. 100.00 m. Calculate the reduced levels of all points by Height of Instrument (Height of Collimation) method and apply checks.

What is meant by traversing? Explain the methods of traversing with a theodolite.

Derive the expressions for horizontal distance and vertical elevation (D and V formulae) for a tacheometer with inclined line of sight and vertically held staff.

Explain the need and characteristics of a transition curve and derive the equation for an ideal transition curve (clothoid).

Differentiate between prismatic compass and surveyor's compass.

Explain the temporary adjustments (setting up) of a theodolite, including its fundamental lines/axes.

Stadia readings were taken with a theodolite on a vertical staff with the telescope inclined at an angle of depression of 3630'. The staff readings were 2.990, 2.055 and 1.120. The R.L. of the staff station is 100.00 m and height of instrument is 1.40 m. Determine the R.L. of the instrument station ground and its horizontal distance from the staff.

Explain the two-point problem of plane table surveying with a neat sketch.

Define vertical curve. Explain the types of vertical curves and their uses/applications.

What is sounding in hydrographic surveying? Explain its uses and methods briefly.

Explain aerial photography and its uses in civil engineering. What are the different types of aerial photographs?
