Which of the following is NOT a type of leveling instrument?
A Dumpy level
B Automatic level
C Prismatic compass
D Tilting level
A prismatic compass is used to measure bearings and directions, not for leveling. Leveling instruments like the dumpy level, automatic level, and tilting level are specifically designed to determine elevation differences between points.
In chain surveying, what is the purpose of an offset?
A To measure horizontal distances
B To measure vertical angles
C To measure perpendicular distances from a chain line
D To measure slopes
Offsets are used in chain surveying to measure perpendicular distances from the main chain line to the details of the survey, such as boundaries or buildings. This helps in accurately plotting the features on the map.
Which of the following is a disadvantage of chain surveying?
A High accuracy
B Suitable for large areas
C Affected by obstacles like rivers and hills
D Requires advanced instruments
Chain surveying is not suitable for areas with obstacles like rivers, hills, or dense vegetation, as it requires a clear line of sight and flat terrain. It is also less accurate compared to modern surveying methods.
What is the term for the process of transferring points from a map to the ground?
A Plotting
B Setting out
C Triangulation
D Traversing
Setting out is the process of transferring points, lines, and levels from a map or design plan to the ground. It is commonly used in construction projects to ensure that structures are built according to the design.
Which of the following instruments is used for measuring both horizontal and vertical distances?
A Theodolite
B Total station
C Dumpy level
D Prismatic compass
A total station is an electronic instrument that can measure both horizontal and vertical distances, as well as angles. It combines the functions of a theodolite and an Electronic Distance Measurement (EDM) device.
What is the term for the process of measuring the alignment of a pipeline?
A Alignment survey
B Triangulation
C Traversing
D Leveling
An alignment survey is conducted to measure and establish the alignment of pipelines, roads, or railways. It involves setting out straight lines, curves, and gradients to ensure that the infrastructure is constructed according to the design specifications.
Which of the following is a type of error in surveying?
A Systematic error
B Random error
C Gross error
D All of the above
Errors in surveying can be classified into three types: systematic errors (due to instrument calibration or environmental factors), random errors (due to human or environmental variability), and gross errors (due to mistakes or blunders).
What is the term for the process of measuring the area of a plot using a planimeter?
A Planimetry
B Graphical method
C Triangulation
D Traversing
Planimetry is the process of measuring the area of a plot using a planimeter, a mechanical or digital instrument. The planimeter traces the boundary of the plot on a map, and the area is calculated based on the movement of the tracing arm.
Which of the following is a type of traverse in surveying?
A Open traverse
B Closed traverse
C Both a and b
D None of the above
A traverse can be either open (starting and ending at different points) or closed (starting and ending at the same point). Both types are used in surveying, depending on the requirements of the project.
What is the term for the process of measuring the alignment of a railway track?
A Alignment survey
B Triangulation
C Traversing
D Leveling
An alignment survey is conducted to measure and establish the alignment of railway tracks, roads, or pipelines. It involves setting out straight lines, curves, and gradients to ensure that the infrastructure is constructed according to the design specifications.
Which of the following is a type of leveling staff?
A Self-reading staff
B Target staff
C Both a and b
D None of the above
A leveling staff can be either self-reading (read directly by the surveyor through the telescope) or target (read using a target that is moved up and down the staff). Both types are used in leveling surveys.
What is the term for the process of measuring the alignment of a canal?
A Alignment survey
B Triangulation
C Traversing
D Leveling
An alignment survey is conducted to measure and establish the alignment of canals, roads, or pipelines. It involves setting out straight lines, curves, and gradients to ensure that the infrastructure is constructed according to the design specifications.
Which of the following is a type of error in leveling?
A Collimation error
B Parallax error
C Both a and b
D None of the above
Errors in leveling can include collimation error (due to misalignment of the instrument) and parallax error (due to improper focusing of the telescope). Both errors can affect the accuracy of leveling measurements.
What is the term for the process of measuring the alignment of a transmission line?
A Alignment survey
B Triangulation
C Traversing
D Leveling
An alignment survey is conducted to measure and establish the alignment of transmission lines, roads, or pipelines. It involves setting out straight lines, curves, and gradients to ensure that the infrastructure is constructed according to the design specifications.
Which of the following is a type of leveling instrument?
A Dumpy level
B Automatic level
C Tilting level
D All of the above
Leveling instruments include the dumpy level, automatic level, and tilting level. These instruments are used to determine elevation differences between points and are essential for construction and topographic surveys.
