Abstract: With the continuous development of society and economy, the quality of life of Chinese residents has been greatly improved. At present, no matter in cities or towns, the demand for power is increasing, but there are many problems in the construction process of power engineering to be solved. In order to improve the construction quality of power engineering, many advanced technologies have been continuously developed. Among them, the surveying and mapping technology of electric power engineering is to measure and describe the construction environment of electric power engineering by using measuring equipment, so as to provide basis for the construction of electric power engineering and improve the construction quality.
