They can meet the various conditions required for measurement work, such as orientation, distance measurement, and height measurement. There are various types of surveying and mapping instruments. Among them, the total station surveying and mapping device is composed of an electronic theodolite, an electromagnetic wave rangefinder, a microcomputer, a program module, a memory, and an automatic recording device. It is a multifunctional electronic measuring instrument that can quickly measure distance, angle, calculate, and record. It was developed in the process of automating angle measurement and is widely used in precision engineering measurement or deformation monitoring such as large-scale above-ground buildings and underground tunnel construction. In the existing technology, the total station can calculate the distance between the instrument and the target, can be leveled by observing the position of the bubble, and can be adjusted in height by telescoping the tripod.
