What is Surveying?
What is Surveying?
Surveying is the science and art of determining the relative positions of points on or near the surface of the earth, by measuring distances, angles, and elevations.
What is the Principle of Surveying?
What is the Principle of Surveying?
The principle of surveying is based on the concept of triangulation. This involves dividing a large area into smaller triangles and measuring the sides and angles of these triangles to determine the precise locations of points.
What is Levelling?
What is Levelling?
Levelling is a surveying technique used to determine the difference in elevation between points. It involves using a level instrument to create a horizontal plane and then measuring the vertical distance from that plane to the points of interest.
