List of top Surveying Questions asked in GATE Civil Engineering

A surveyor measured the distance between two points on the plan drawn to a scale of 1 cm = 40 m and the result was 468 m. Later, it was discovered that the scale used was 1 cm = 20 m.
The true distance between the points (in m) is __________ (round off to the nearest integer).
 

A delivery agent travels from $R$ to $P$ along straight-line paths $RC$, $CA$, $AB$, and $BP$, each of length $5\,$km. The whole circle bearings (clockwise from North) are: $RC=120^\circ$, $CA=0^\circ$, $AB=90^\circ$, $BP=240^\circ$. If the latitude $(L)$ and departure $(D)$ of $R$ are $(0,0)$ km, find the latitude and departure of $P$ (rounded to one decimal place). \includegraphics[width=0.75\linewidth]{image666.png}
If the size of the ground area is $6 \,\text{km \times 3 \,\text{km}$ and the corresponding photo size in the aerial photograph is $30 \,\text{cm} \times 15 \,\text{cm}$, then the scale of the photograph is $1 : \underline{\hspace{3cm}}$ (in integer).}
The magnetic bearing of the sun for a location at noon is $183^\circ 30'$. If the sun is exactly on the geographic meridian at noon, the magnetic declination of the location is \underline{\hspace{1.5cm}.}
Trigonometric levelling was carried out from two stations P and Q to find the reduced level (R.L.) of the top of hillock, as shown in the table. The distance between Stations P and Q is 55 m. Assume Stations P and Q, and the hillock are in the same vertical plane. The R.L. of the top of the hillock is \underline{\hspace{2cm} (round off to three decimal places).} \includegraphics[width=1.0\linewidth]{image143.png}
The direct and reversed zenith angles observed by a theodolite are $56^\circ 00' 00''$ and $303^\circ 00' 00''$, respectively. What is the vertical collimation correction?
