What is engineering survey technology?

Engineering investigation usually refers to various investigation theories, methods and technologies adopted in the investigation, design, construction and management stages of engineering construction.

The service fields of traditional engineering survey technology include construction, water conservancy, transportation, mining and other departments, and its basic contents include surveying and mapping and lofting. Modern engineering survey has gone far beyond the concept of only serving engineering construction. It not only involves the measurement of static and dynamic geometric and physical quantities of engineering, but also includes the analysis of measurement results and even the trend prediction of object development and change.

Study the landform characteristics of the construction site and the monitoring technology for construction and safe use, and provide necessary basic maps, surveying and mapping data and surveying and mapping support for the planning, design, construction and operation management stages.

Professor mathis of Zurich University of Technology pointed out: "All land surveys that do not belong to geodesy, national atlases that do not belong to statutory surveys and applied surveys belong to engineering surveys". With the transformation from traditional surveying and mapping technology to digital surveying and mapping technology, the development of engineering surveying in China can be summarized as "four modernizations" and "sixteen characters". The so-called "four modernizations" are: the integration of engineering survey indoor and outdoor work, the automation of data acquisition and processing, the intelligent control of measurement process and system behavior, and the digitalization of measurement results and products. "Sixteen characters" are: continuous, dynamic, telemetry, real-time, accurate, reliable, fast and simple.

Cultivate advanced technical application-oriented professionals who master the basic theoretical knowledge and basic surveying and mapping skills necessary for surveying engineering specialty and engage in engineering construction surveying. Focusing on the goal of talent training in higher vocational colleges, the major of engineering surveying technology is based in Sichuan and facing the whole country, and cultivates high-skilled talents with all-round development in morality, intelligence, physique and aesthetics, who can master the basic theory and skills of surveying and be engaged in various engineering surveying, cadastral surveying production, management and service. When students graduate, in addition to obtaining academic certificates, they must also obtain vocational skill appraisal certificates issued by at least one country.
