A land surveyor is a professional who uses geometrical techniques to measure surface areas and bearings of land. This used to be done with chains having links of known length, and a compass to fix bearings. Using modern technology the surveying profession has evolved and is now applied in many fields.
Today, the surveyor can be called for in the planning and execution of many types of construction. Surveying in Europe was introduced by Napoleon who brought in the concept of land plots.
