Surveying and Levelling are fundamental subjects in Civil Engineering that involve determining the relative positions of points on the earth's surface. They are crucial for planning and executing civil engineering projects.
Surveying:
- The process of measuring distances, angles, and elevations to map the surface of the earth. It helps in understanding the topography of the land and creating maps or plans for construction projects.
- A specialized part of surveying that focuses on measuring the height differences between points to determine their relative elevations. It is used to establish a horizontal plane for construction activities.
Land Mapping and Planning:
- Used to create detailed maps and layouts for urban planning, roadways, and infrastructure.
- Essential for laying out foundations, roads, bridges, dams, and buildings.
- Levelling ensures proper drainage and slope alignment for roads and canals.
- Helps in establishing legal property boundaries and dispute resolution.
- Facilitates the study of terrain for environmental assessments and agricultural planning.
