Surveying and mapping requires deep mathematical knowledge. Advanced mathematics, linear algebra, probability theory and mathematical statistics, especially linear algebra and probability theory, are very important. Error theory is supported by probability theory, and you will learn many formulas to deduce and push around. Even with advanced mathematics and linear algebra, it is quite difficult to learn the theory of surveying and mapping.

Surveying and mapping specialty is the abbreviation of surveying and mapping specialty. This major mainly studies the basic theories and technologies of space, electronics, information, laser, inertia and other sciences, and studies the basic theories and methods of using these technologies to determine the shape of the earth and other stars, the three-dimensional characteristics of buildings (structures) and their relationship with the designated reference system, the gravity field of the earth and its internal physical characteristics, the characteristics of moving objects and its multi-dimensional parameters, and the application of these technologies in engineering, industry and human life.
