A theodolite is a precision instrument used to measure horizontal and vertical angles. It was made in 1752 and is commonly used in geographic mapping and engineering. Theodolite belongs to the early measuring instrument, which is very precise in design and technology, which laid the foundation for the later measuring instrument. In the 1752 theodolite, craftsmen used precision machining techniques to ensure the accuracy of the measurement. These early theodolites played an important role in geographic mapping, engineering construction and astronomical research, helping people to accurately determine position and angle.
