Leveling is used to determine the height or elevation difference between two or more points. It is essential in construction and land development for ensuring correct foundation placement.
Which instrument is used to measure horizontal distances?
A Compass
B GPS
C Chain
D Theodolite
A chain is traditionally used in surveying to measure horizontal distances, especially for small-scale surveys. It is simple and effective for measuring relatively short distances on the ground.
What does a total station combine?
A Leveling and chain
B Theodolite and EDM
C GPS and theodolite
D EDM and compass
A total station combines the functionality of a theodolite (for measuring angles) and an EDM (for measuring distances), making it a versatile tool for modern surveying.
What type of survey is used to measure land boundaries?
A Cadastral survey
B Alignment survey
C Topographic survey
D Hydrographic survey
Cadastral surveys are used to determine and record land boundaries. They are essential for land ownership, resolving property disputes, and creating legal documents.
What is triangulation used for in surveying?
A Plotting boundaries
B Determining locations
C Measuring distances
D Mapping the terrain
Triangulation helps in determining the precise location of a point by measuring angles from known points, commonly used in geodetic and large-scale mapping surveys.
What do contour lines on a map represent?
A Coordinates
B Boundaries
C Elevation
D Distance
Contour lines connect points of equal elevation on a map. They help represent the shape and steepness of the terrain, which is useful in planning construction and navigation.
What is the purpose of a GPS in surveying?
A Measuring angles
B Measuring area
C Determining position
D Measuring height
GPS (Global Positioning System) is used in surveying to determine precise geographic locations, including latitude, longitude, and elevation, making it crucial for large-scale mapping and geodetic surveys.
What is the function of a theodolite in surveying?
A Measure horizontal and vertical angles
B Measure height
C Measure vertical angles
D Measure horizontal distances
A theodolite is used to measure both horizontal and vertical angles. It is essential for tasks such as triangulation, boundary surveys, and setting out during construction.
What is a plane table survey used for?
A Measuring angles
B Measuring distances
C Measuring elevation
D Drawing maps in the field
A plane table survey allows surveyors to draw maps directly in the field, making it a useful tool for rapid data collection and mapping in small areas.
What is the primary purpose of contouring in surveying?
A To show boundaries
B To map terrain elevation
C To measure distance
D To show water bodies
Contouring helps represent the elevation changes in the terrain. It is widely used to visualize slopes, hills, valleys, and other landforms, helping in construction and planning.
Which instrument is essential for measuring vertical angles?
A Tape measure
B Chain
C Compass
D Theodolite
Theodolites are used to measure both horizontal and vertical angles with high precision. They are critical for tasks that require precise elevation measurements and angle determination, such as leveling and building construction.
Which method is used for calculating the volume of earthwork?
A Volume calculation
B Simpson’s rule
C Area calculation
D Triangulation
Volume calculation determines the amount of earthwork needed for construction, such as excavation and filling. It uses measurements of area and depth to compute the total volume of material involved.
What is the purpose of a plumb bob in surveying?
A Measure distances
B Measure angles
C Establish vertical alignment
D Calculate volume
A plumb bob is a weight attached to a string, used to establish a vertical reference line. It helps in ensuring vertical alignment during tasks like leveling and setting up instruments.
What does a hydrographic survey measure?
A Soil composition
B Water depth and seabed
C Building alignment
D Land boundaries
Hydrographic surveys measure underwater features such as water depth, the shape of the seabed, and submerged objects. These surveys are essential for navigation, marine construction, and flood management.
What is the role of electronic surveying tools?
A Measure distances
B Increase survey speed and accuracy
C Measure angles
D Measure data
Electronic surveying tools, such as total stations and GPS, greatly enhance the efficiency and accuracy of surveys. They automate data collection, reducing human error and speeding up the survey process.
