Q1. A topographic survey of a rectangular plot measures the following elevations at four corners (in meters): A=120, B=125, C=123, D=118. Calculate the average elevation of the plot.
- 121.5 m
- 121.0 m
- 121.5 m
- 121.0 m
Q2. A survey line has a fore bearing of 70°. What is the back bearing of this line?
- 250°
- 110°
- 70°
- 290°
Q3. During compass surveying, a surveyor notices that the magnetic needle does not point exactly to the magnetic north but is deflected by a certain angle. What is this phenomenon called?
- Magnetic declination
- Local attraction
- Magnetic dip
- Variation
Q4. Conceptually, how does a topographic survey differ from a cadastral survey in terms of data collected and purpose?
- Topographic surveys focus on elevation and natural features; cadastral surveys focus on legal boundaries.
- Topographic surveys measure soil composition; cadastral surveys measure water depth.
- Topographic surveys are used only in urban areas; cadastral surveys are used only in rural areas.
- Topographic surveys are less accurate than cadastral surveys in all cases.
Q5. Which of the following instruments is essential for establishing the true north direction during a surveying operation?
- Prismatic Compass
- Plane Table
- Dumpy Level
- Chain
Q6. Which of the following statements correctly compares the objectives of surveying and levelling?
- Surveying determines horizontal positions only, while levelling determines vertical positions only
- Surveying and levelling both measure soil properties for conservation
- Levelling is a subset of surveying focused on determining elevations
- Levelling is unrelated to surveying and used only in construction
Q7. A surveyor measures a baseline of 150 m using a chain. If the chain length is 20 m but the chain is found to be 0.2 m too long, what is the corrected length of the baseline?
- 149.25 m
- 150.75 m
- 149.50 m
- 150.00 m
Q8. In a scenario where you need to establish a horizontal plane for construction, which surveying instrument would you select and why?
- Theodolite, because it measures angles precisely
- Leveling Instrument, because it helps determine elevation differences
- Tachometer, because it measures distances quickly
- Compass, because it shows direction
Q9. If a surveyor measures the horizontal distance between two points as 150 meters and the vertical difference in elevation as 10 meters, what is the slope between these points? (Slope = vertical difference / horizontal distance)
- 0.067
- 15
- 140
- 1.5
Q10. In compass surveying, what is the difference between fore bearing and back bearing of a survey line?
- Fore bearing is the angle measured clockwise from magnetic north to the line; back bearing is the angle measured counterclockwise
- Fore bearing is the bearing of a line in the forward direction; back bearing is the bearing of the same line in the opposite direction
- Fore bearing is always less than 90°, back bearing is always greater than 90°
- Fore bearing is the true north bearing; back bearing is the magnetic north bearing
Q11. Which type of survey is primarily used to establish the boundaries and ownership of land parcels?
- Topographic Survey
- Cadastral Survey
- Geological Survey
- Hydrographic Survey
Q12. Compare the uses of a chain and a tape in surveying. Which of the following statements is most accurate?
- Chains are more accurate than tapes for measuring long distances
- Tapes are generally preferred over chains due to ease of handling and accuracy
- Chains are used only for leveling, tapes only for angle measurement
- Both chains and tapes are obsolete and never used in modern surveying
Q13. What is the primary objective of surveying in soil conservation engineering?
- To measure soil moisture content accurately
- To determine the relative positions of points on or near the earth's surface
- To analyze chemical properties of soil samples
- To design irrigation systems for agricultural fields
Q14. In chain surveying, why is it important to select well-defined and intervisible stations?
- To ensure accurate measurement of vertical angles
- To facilitate easy chaining and correct plotting of the survey
- To reduce the need for levelling instruments
- To avoid the use of offsets during the survey
Q15. An assistant engineer is tasked with planning a survey to map the contours and elevation changes of a hilly terrain for soil conservation planning. Which survey type should be selected and why?
- Cadastral Survey, to define land ownership for conservation zones.
- Topographic Survey, to capture elevation and terrain features.
- Hydrographic Survey, to measure water bodies affecting the terrain.
- Geological Survey, to analyze soil types and rock formations.
