Mapping

Mapping is the process of representing the surface of the earth, objects on it, and the relative positions of the objects, to a suitable scale. In mapping, a large area of land is measured, surveyed, and plotted. The details of the objects present in the nearby surrounding area are located using conventional signs. All these processes are carried out on a flat paper known as a map.
