Economic development and progress have promoted various technologies to advance by leaps and bounds, especially information technology. The popularization and application of new scientific and technological achievements such as computer, microelectronics and space information technology have greatly improved the technical ability of engineering surveying and mapping in China. With the increasing demand for surveying and mapping information, the application of technology has improved the service quality more accurately, directly promoted the mutual development of surveying and mapping technology and information technology, and achieved comprehensive integration and integration. Under the background of informationization and science and technology, it is of great practical significance to comprehensively discuss the application of surveying and mapping technology to promote the development of information technology and surveying and mapping technology. Keywords: information technology; Surveying and mapping technology; With the development of social and economic life, the demand for surveying and mapping information is increasing, and the demand for surveying and mapping information in all walks of life is increasing rapidly. This increase in demand directly promotes the progress of surveying and mapping technology objectively, showing a trend of synchronous integration with information technology. With the improvement and development of modern information technology, the data service of geographic information has been fully realized, and the premise of the development of digital surveying and mapping technology is information technology. The organic combination of the two has greatly promoted the integration and progress of technology. When technology is applied to the civil industry to a certain extent, technology has completely affected the development direction of the industry and fundamentally promoted social development and economic promotion. This change in orientation shows us the future development of surveying and mapping technology. Information mapping technology is a brand-new technology, mainly based on the needs of production and life, combined with the concept of actual space, with scientific measurement methods, through different sensors, supplemented by corresponding instruments, from the whole to the part.
