What does cartography give us?

Surveying and mapping specialty is the abbreviation of surveying and mapping specialty. It is based on computer technology, photoelectric technology, network communication technology, space science and information science, with global navigation satellite positioning system (GNSS), remote sensing (RS) and geographic information system (GIS) as its technical core. It selects the existing characteristic points and boundaries on the ground, and obtains the graphics and position information reflecting the current situation of the ground through measurement, which can be used in engineering construction, planning and design and administrative management.

In the process of development, surveying and mapping has formed sub-disciplines such as geodesy, general surveying, photogrammetry, engineering surveying, marine surveying and mapping and cartography.

Among them 1, the popular understanding of geodesy is the science of measuring and describing the earth's surface. 2. General surveying is a subject that studies the basic theories, instruments and methods of surveying and mapping in local areas of the earth's surface, and is the basic part of surveying and mapping. 3. Photogrammetry is a science and technology to study and determine the shape, size, nature and relationship of the photographed object by using the images taken by optical cameras. 4. Engineering Surveying is a subject that studies all kinds of surveying work in the stages of survey, design, construction and operation management of all kinds of engineering construction. 5. Ocean mapping is the mapping of ocean water and seabed.

Graduates majoring in Surveying and Mapping Engineering are suitable to engage in engineering surveying and scientific research in the systems and scientific research units of Surveying and Mapping Bureau, and to engage in surveying, construction and operation in various engineering construction departments (electric power, water conservancy, urban construction, military, energy, transportation, etc.). ) and related industrial and mining enterprises (such as metal mines, petroleum, geology, coal, etc.). ). The positions available for measurement are: civil engineer, civil engineer, surveyor and surveyor.
