It requires an understanding of various survey and levelling instruments, carrying out surveys of land and preparation of survey plans. Surveying is the technique and science of accurately determining the terrestrial or three-dimensional space position of points and the distances and angles between them. In order to accomplish their objective, surveyors use elements of geometry (Greek: measuring the Earth), engineering, mathematics, physics, and law. This data forms the basis of plans used for civil engineering and construction projects, such as new transport infrastructure – roads, tunnels and bridges; land redevelopment, mining, quarrying and waste management operations; and installation of power, energy and water supply networks.

What do I have to do?

Surveyors measure distances, directions, and angles between points and elevations of points, lines, and contours on, above, and below the earth’s surface. In the field they select known survey reference points, and determine the precise location of important features in the survey area...
