Definition of Surveying

Surveying has to do with the determination of the relative spatial location of points on or near the surface of the earth.
• It is the art of measuring horizontal and vertical distances between objects, of measuring angles between lines, of determining the direction of lines, and of establishing points by predetermined angular and linear measurements.
• Along with the actual survey measurements are the mathematical calculations.
• Distances, angles, directions, locations, elevations, areas, and volumes are thus determined from the data of the survey.
• Survey data is portrayed graphically by the construction of maps, profiles, cross sections, and diagrams.

Importance of Surveying:

Land surveying is basically an art and science of mapping and measuring land. The entire scope of profession is wide; it actually boils down to calculate where the land boundaries are situated. This is very important as without this service, there would not have been railroads, skyscrapers could not have been erected and neither any individual could have put fences around their yards for not intruding others land.
