Leveling is used to determine the vertical height or elevation difference between two or more points. It is essential for construction, ensuring structures are built on level ground.
What instrument is used to measure horizontal angles?
A Theodolite
B Clinometer
C Total station
D Compass
A theodolite measures both horizontal and vertical angles. It is widely used in tasks such as triangulation, boundary surveys, and setting out for construction projects.
What is the primary purpose of a total station?
A Plot survey data
B Measure both angles and distances
C Measure angles only
D Measure distances only
A total station is an advanced instrument that combines a theodolite and Electronic Distance Measurement (EDM) capabilities, allowing surveyors to measure both angles and distances at the same time.
What is the main advantage of GPS in surveying?
A Measure height
B Measure angles
C Plot data
D Provide precise location data
GPS (Global Positioning System) allows surveyors to obtain highly accurate geographic coordinates (latitude, longitude, and elevation) for any point on Earth, making it essential for large-scale surveys.
What is triangulation used for in surveying?
A Determine distances and locations
B Measure angles
C Plot data
D Measure height
Triangulation is used to calculate the location of unknown points by measuring angles from known reference points. It is essential in large-scale surveys.
What is a contour line on a map?
A A line showing boundaries
B A line showing elevation
C A line showing roads
D A line showing distances
Contour lines connect points of equal elevation on a map, helping to visualize the topography of the land. They indicate slopes, hills, and valleys.
What instrument measures distances electronically?
A GPS
B Chain
C Compass
D EDM
EDM (Electronic Distance Measurement) devices are used to measure distances electronically using signals such as lasers. These devices provide highly accurate measurements over long distances.
What is the purpose of chain surveying?
A Measure vertical distances
B Measure contours
C Measure horizontal distances
D Measure angles
Chain surveying is used to measure horizontal distances on the ground, typically with a measuring chain or tape. It is most effective in small areas without complex terrain.
What type of survey is used to determine land ownership boundaries?
A Alignment survey
B Hydrographic survey
C Cadastral survey
D Topographic survey
A cadastral survey is specifically designed to determine property boundaries. It is essential for land registration, legal disputes, and urban planning.
Which survey method measures underwater features?
A Hydrographic survey
B Cadastral survey
C Topographic survey
D Chain surveying
Hydrographic surveys are conducted to measure underwater features like the depth of water bodies, the seabed, and submerged objects. It is crucial for navigation and marine construction.
What is the function of a leveling staff?
A Plot survey data
B Measure height difference
C Measure angles
D Measure distances
A leveling staff is a graduated rod used with leveling instruments to determine the difference in elevation between two points. It is essential for tasks such as road construction.
What is the purpose of triangulation in a survey?
A Measure distance
B Measure angles
C Measure elevation
D Determine location
Triangulation helps determine the location of a point by measuring angles from two known points. This method is especially useful for large surveys and geodetic measurements.
What is the primary function of a plumb bob?
A Plot boundaries
B Measure distances
C Establish vertical alignment
D Measure angles
A plumb bob is a weight on a string used to establish a vertical reference line, ensuring accurate vertical alignment for tasks like leveling and setting up surveying instruments.
What does a compass measure in surveying?
A Height
B Angles
C Distance
D Elevation
A compass is used in surveying to measure horizontal angles relative to magnetic north. It helps establish directions and bearings during compass surveying.
What is the purpose of remote sensing in surveying?
A Collect data from a distance
B Plot maps
C Measure angles
D Measure distances
Remote sensing collects data about Earth’s surface using satellites or aerial sensors. It helps in large-scale surveys, environmental monitoring, and geospatial analysis, providing valuable information for decision-making.
