a) Availability of surveyors
b) Budget constraints
c) Physical characteristics of the site
d) Previous surveying experience
View Answer
Correct answer: c) Physical characteristics of the site
Explanation: The physical characteristics of the project site, such as topography, soil composition, and accessibility, should be considered when selecting a suitable surveying method.
63. What is the purpose of using scales on plans and maps?
a) To determine surveying costs
b) To represent features in proportionate sizes
c) To determine land boundaries
d) To calculate area and volume measurements
View Answer
Correct answer: b) To represent features in proportionate sizes
Explanation: Scales on plans and maps are used to accurately represent features, distances, and areas in proportionate sizes, enabling accurate measurement and visualization.
64. Which document is used to record field observations and measurements during a surveying project?
a) Specifications
b) Field notes
c) Blueprints
d) Profiles
View Answer
Correct answer: b) Field notes
Explanation: Field notes, also known as field records or field books, are used to record field observations, measurements, sketches, and other relevant data during a surveying project.

a) Geodetic surveying
b) Cadastral surveying
c) Topographic surveying
d) Engineering surveying
View Answer
Correct answer: d) Engineering surveying
Explanation: Engineering surveying involves precise measurements and mapping of land features for engineering design, construction, and infrastructure projects.
66. What is the primary consideration when selecting a suitable surveying method?
a) Surveyor’s experience
b) Availability of equipment
c) Accuracy requirements
d) Project timeline
View Answer
Correct answer: c) Accuracy requirements

67. Which type of scale uses words or descriptions to represent map distances?
a) Representative fraction (RF) scale
b) Verbal scale
c) Graphical scale
d) Linear scale
View Answer
Correct answer: b) Verbal scale
Explanation: A verbal scale uses words or descriptions to represent map distances, such as “1 inch equals 1 mile” or “1 centimeter equals 1 kilometer.”

a) Geodetic surveying
b) Cadastral surveying
c) Topographic surveying
d) Hydrographic surveying
View Answer
Correct answer: c) Topographic surveying
Explanation: Topographic surveying involves mapping the natural and man-made features of a specific area, including contours, vegetation, buildings, and water bodies.
69. What is the primary purpose of entry into survey field books and level books?
a) To maintain a log of surveying equipment
b) To document surveying calculations and measurements
c) To record weather conditions during the survey
d) To track surveyor’s work hours
View Answer
Correct answer: b) To document surveying calculations and measurements
Explanation: Entry into survey field books and level books involves documenting surveying calculations, measurements, and other important data for reference and analysis.
70. Which survey classification focuses on precise measurements of large areas to establish a coordinate system?
a) Geodetic surveying
b) Cadastral surveying
c) Topographic surveying
d) Control surveying
View Answer
Correct answer: a) Geodetic surveying
