What is the primary function of compass surveying?
A Measure distances
B Measure height
C Establish directions
D Measure angles
Compass surveying is used to establish directions and bearings in a survey. It is commonly used for small-scale surveys, especially in boundary determination and road layout.
What is an alignment survey used for?
A Measure area
B Set out construction lines
C Calculate volume
D Measure distance
An alignment survey is used to establish and mark the alignment of roads, railways, pipelines, and other infrastructure. It ensures that construction follows the design specifications for proper placement.
Which tool is commonly used in construction layout surveys?
A Chain
B Clinometer
C Theodolite
D Total station
A total station is commonly used in construction layout surveys. It measures angles and distances simultaneously, providing high accuracy for laying out construction lines, points, and elevations.
What is hydrographic surveying used for?
A Measuring water depth
B Establishing boundaries
C Measuring height
D Measuring distance
Hydrographic surveying is used to measure water depth and seabed features. It is essential for navigation, dredging, and marine construction, providing detailed data on underwater conditions.
What is the purpose of survey software in modern surveying?
A Plot maps
B Measure distance
C Improve accuracy and speed
D Measure angles
Survey software is used to process data, perform calculations, and create accurate maps. It enhances the efficiency, accuracy, and speed of surveys, reducing human error and improving overall survey quality.
What does a boundary survey establish?
A Road locations
B Terrain features
C Water flow patterns
D Property boundaries
A boundary survey determines and defines the legal boundaries of a property. It is used to resolve disputes, establish ownership, and prepare legal documents like deeds.
What is the first step in fieldwork methods for surveying?
A Collecting data
B Setting up instruments
C Measuring distances
D Plotting maps
The first step in fieldwork is to set up the necessary instruments like theodolites, total stations, or GPS equipment. This ensures that measurements and data collection are accurate throughout the survey.
What is the purpose of using a theodolite in fieldwork?
A Measure horizontal and vertical angles
B Plot data
C Measure elevation
D Measure distances
A theodolite is used to measure both horizontal and vertical angles, which is essential for triangulation, boundary surveys, and determining precise locations during field surveys.
What does a boundary survey help to define?
A Elevation
B Roads
C Property boundaries
D Water levels
A boundary survey helps define and establish the exact limits of a property. It is often required for legal purposes, such as land transfers, dispute resolution, and construction projects.
What is the primary function of a clinometer in surveying?
A Measure angles
B Measure slope
C Measure elevation
D Measure distances
A clinometer is used to measure the slope or incline of land. It is commonly used in environmental studies, forestry, and construction to assess terrain steepness for various projects.
What is the key feature of a total station in surveying?
A Measures angles only
B Measures distance only
C Measures both angles and distances
D Only plots data
A total station combines the functions of a theodolite and an EDM (Electronic Distance Measurement) device, allowing it to measure both angles and distances simultaneously with high precision.
What is a primary use of compass surveying?
A Determining direction
B Plotting maps
C Measuring distances
D Measuring angles
Compass surveying is primarily used for determining directions and bearings. It is a simple and effective method for small-scale surveys, such as property boundary and road surveys.
What method is used to measure the height of objects in surveying?
A Remote sensing
B Leveling
C Triangulation
D Area calculation
Leveling is used to measure the vertical height or elevation difference between two points. It is essential for construction projects like roads, bridges, and drainage systems.
What is the function of electronic surveying tools?
A Measure elevation
B Plot terrain features
C Measure distance and angles
D Measure area
Electronic surveying tools, such as total stations and GPS, are designed to measure both angles and distances. These tools improve survey speed and accuracy, making them essential in modern surveying practices.
What is the purpose of curve setting in surveying?
A Layout curves for roads or railways
B Calculate area
C Plot boundaries
D Measure elevation
Curve setting involves determining the radius, deflection angles, and chord lengths for curves in road or railway construction. It ensures smooth transitions between straight and curved sections for safety and efficiency.
