[0002] The main purpose of architectural surveying is to measure and map existing buildings or their groups so as to study, protect and repair them. Generally speaking, architectural surveying is to measure the characteristic points and boundaries of buildings by hand and modern instruments, and draw the measurement results into graphics, which are used for the protection, repair and research of buildings. Architectural surveying plays an important role in architecture. It not only involves the measurement of the current status of buildings, but also includes the study of their history, structure and maintenance. Through architectural surveying, we can better understand the design and construction process of buildings, thus providing a basis for subsequent protection and repair.
