Surveying and Its Uses
Generally, before start of any engineering works a topographical plan or map with horizontal and vertical measurements are required.
These maps are created using the concept termed as Surveying.
Surveying is the art of determining the relative positions of points on, above or beneath the surface of the earth.
It is generally done by the means of direct or indirect measurements of distance, direction and elevation.
Surveying also includes establishing points by predetermined linear and angular measurements.
Levelling is the branch of surveying, which is used in determining relative elevation of an object with respect to datum line and to establish the points at a given elevation or at different elevations with respect to a given or assumed datum.
Let us now discuss uses of surveying.
Surveying is used in preparing a topographical map which represents hills, valleys, villages, towns, forest etc.
It is also used in preparing an engineering maps which shows the details of engineering works, such as roads, railways, reservoirs, irrigation canals, etc.
It is used in preparing a cadastral map which shows the boundaries of fields, houses and other properties.
It is used in preparing the military map, which shows the roads, railways and communications with different parts of a country.
It is used in preparing a contour map to determine the capacity of a reservoir, which also helps to find best possible transportation routes.
It is used in preparing a geological map showing areas of natural resources.
It is also used in preparing an archaeological map showing ancient places.
