Abstract: The digital surveying and mapping technology represented by PTK positioning technology, surface surveying and mapping technology and aerial surveying and mapping technology has realized the operation processes of data information collection, transmission and processing of artificial intelligence, and improved the construction quality and efficiency of various land survey projects. As for the technology is in the development stage of high and new technology, the management of relevant laws and regulations and quality inspection standards are more stringent, and more attention is paid to the quality of external real-time drawing and internal computer system processing. The current digital surveying and mapping technology makes the construction of land surveying engineering more intelligent and accurate through the satellite positioning function of GPS technology or the measurement function of total station, combined with digital photogrammetry technology, remote control technology and mapping software measurement technology.
