Most of the activities a surveyor carries out in the context of his professional tasks needs measurement. Traditionally, the community looks at the surveyor as an expert skilled in land measurement. For this reason, they expect him to collect information about land. Therefore, such a requirement necessitates measurement and its application in mathematical formulas.
Measurement, in the real sense, is more than what it appears. Although, from the perspective of an operator, it is possible to restrict measuring entirely to field operations, a particular person needs to have a deeper look, and field measurements are only a small part of measurement work and steps to provide the information necessary for next steps. In addition, before field measuring, it is necessary to design measuring work according to the precision that is ultimately needed.
