📌 WHAT IS SURVEYING?
- Process of measuring distances, angles, and elevations
- Determines relative positions of points on, above, or beneath the earth’s surface
📌 TYPES OF SURVEYING
- Plane Surveying – assumes earth is flat for small areas
- Geodetic Surveying – accounts for earth’s curvature, used for large areas
- Topographic Surveying – maps natural & man-made features
- Construction Surveying – guides building layout and infrastructure works
📌 SURVEYING INSTRUMENTS
- Total Station – electronic/optical instrument for angles & distances
- Level – measures elevation differences
- GPS – satellite-based positioning system
📌 SURVEY METHODS
- Triangulation – uses triangles to determine positions
- Traversing – series of connected survey lines
- Levelling – determines height differences
- GPS Survey – uses satellite signals for accuracy
- Training – practical field learning for surveyors
Surveying is one of the most important processes in civil engineering. It helps engineers measure distances, angles, and elevations to determine the exact position of points on the earth’s surface.
Accurate surveying is essential for planning, designing, and constructing roads, buildings, bridges, and other infrastructure.
Different types of surveying such as Plane Surveying, Geodetic Surveying, Topographic Surveying, and Construction Surveying are used depending on the project requirements. Modern instruments like Total Station, Level, and GPS make surveying faster and more precise.
Common survey methods include Triangulation, Traversing, Levelling, and GPS Survey, which help engineers collect accurate data for successful construction projects.
