🌍 What is Surveying? | Introduction to Surveying
Surveying is one of the fundamental and most essential subjects in Civil Engineering. It is the art and science of measuring distances, angles, and elevations to determine the relative positions of points on the earth’s surface. Every construction project starts with surveying.
Without accurate surveying, no civil engineering structure like roads, bridges, buildings, tunnels, or dams can be successfully designed or executed.
🚀 Importance of Surveying in Civil Engineering
Surveying is not just about measurements; it is the foundation of every infrastructure project. Here’s why surveying is important:
✔️ Accurate location and mapping of project sites.
✔️ Helps in preparing site plans and topographical maps.
✔️ Determines land boundaries.
✔️ Essential for layout and alignment of civil engineering structures.
✔️ Reduces project errors, saving time and cost.
🔍 Classification of Surveying | Types of Surveying
Surveying can be classified based on different criteria:
1. Based on Nature of Surface:
Ground Surveying: Surveys conducted on land.
Aerial Surveying: Surveys conducted using drones or aircraft.
2. Based on Instruments:
Chain Surveying: Using chains and tapes for linear measurement.
Compass Surveying: Using compass for measuring bearings.
Plane Table Surveying: Using drawing boards for on-site plotting.
Theodolite Surveying: For measuring both horizontal and vertical angles.
Tacheometric Surveying: Rapid surveying using stadia methods.
Total Station Surveying: Modern digital surveying with distance and angle measurement.
3. Based on Purpose:
Topographical Surveying: Preparation of maps showing natural and man-made features.
Cadastral Surveying: Determination of property boundaries.
Engineering Surveying: Surveys specifically for engineering projects like highways, railways, and buildings.
