31. What is the purpose of using different scales on maps or plans?
a) To indicate the north direction
b) To calculate the area of the land
c) To show the elevation of the land
d) To represent features in their proportionate sizes
View Answer
Correct answer: d) To represent features in their proportionate sizes
Explanation: Different scales on maps or plans allow surveyors to represent features in their proportionate sizes. This ensures accurate measurement and visualization of objects or areas represented on the map or plan.
32. Which document shows the vertical representation of the land, including elevations and contours?
a) Scales
b) Plans
c) Maps
d) Profiles

a) Geodetic surveying
b) Cadastral surveying
c) Topographic surveying
d) Engineering Surveying
View Answer
Correct answer: b) Cadastral surveying
Explanation: Cadastral surveying focuses on the measurement and demarcation of land parcels and property boundaries. It plays a crucial role in land administration, property ownership, and land development projects.
35. What principle guides the selection of the most appropriate surveying method for a specific project?
a) Principle of accuracy
b) Principle of efficiency
c) Principle of suitability
d) Principle of cost-effectiveness
View Answer
Correct answer: c) Principle of suitability
Explanation: The principle of suitability guides surveyors in selecting the most appropriate surveying method for a specific project. The chosen method should match the project requirements, site conditions, and available resources.
36. Which document is used to represent the Earth’s surface on a small scale and includes various features such as rivers, mountains, and cities?
a) Scales
b) Plans
c) Maps
d) Profiles
View Answer
Correct answer: c) Maps
Explanation: Maps are used to represent the Earth’s surface on a small scale. They provide a comprehensive view of various features such as rivers, mountains, cities, and other landmarks. Maps are commonly used for navigation and spatial understanding.
37. What is the purpose of entry into survey field books and level books?
a) To record field observations and measurements
b) To create maps and plans
c) To calculate surveying costs
d) To select suitable surveying methods
View Answer
Correct answer: a) To record field observations and measurements
Explanation: Entry into survey field books and level books involves recording field observations and measurements made during a surveying project. These records serve as a reference for analysis, documentation, and future decision-making.
38. Which survey classification focuses on the measurement and mapping of the Earth’s surface on a large scale?
a) Geodetic surveying
b) Cadastral surveying
c) Topographic surveying
d) Engineering Surveying
View Answer
Correct answer: a) Geodetic surveying
Explanation: Geodetic surveying is a survey classification that focuses on the precise measurement and mapping of the Earth’s surface on a large scale. It considers the Earth’s curvature and shape for accurate positioning and mapping.
39. What is the fundamental principle of surveying?
a) Principle of accuracy
b) Principle of precision
c) Principle of reliability
d) Principle of consistency
View Answer
Correct answer: a) Principle of accuracy
Explanation: The fundamental principle of surveying is to achieve accurate measurements and observations. Accuracy is crucial to ensure reliable survey results, which are used for various engineering and construction purposes.
40. When selecting a suitable surveying method, what factor should be considered regarding the project site?
a) Topography
b) Soil composition
c) Accessibility
d) All of the above
View Answer
Correct answer: d) All of the above
Explanation: When selecting a suitable surveying method, surveyors should consider factors such as the topography of the project site, the soil composition, and the accessibility of the area. These factors impact the choice of surveying techniques and equipment.
