Geodesy: Research and determine the Earth's shape, size, and the Earth's gravity field, as well as the geometric location of the ground point of the theory and methods. Geodesy, surveying and mapping the various branches of learning the theoretical basis, the basic task is to establish ground control network, gravity network, accurately determine the three-dimensional position of control points for topographic maps to provide control of the basis for all types of construction to provide a basis for the study of the Earth's shape , size, gravity field and changes in crustal deformation and earthquake prediction information.

General Surveying: To study the Earth's surface, measure and control the local area topographic mapping of the theory and methods. Local area refers to the mapping in the region, we can disregard the curvature of the earth, treat it as a graphic processing, without affecting the mapping accuracy.

Photogrammetry: To study the use of cameras or other sensors capture image information of the detected objects, after processing and analysis to determine the measured object's shape, size and location, and determine the nature of the theory and methods. By distance minutes can be divided into: space photogrammetry, air video measurement, ground shadow measurement, close-range measurements and micro-cephalometric film: According to the different technical approaches can be divided into: simulation video measurement, analytic method and digital cephalometric cephalometric .

Engineering Geodesy: research in the construction design, construction and management of all stages of survey work of the theories, technologies and methods. For project construction to provide accurate measurements and large-scale maps, to protect construction sites is reasonable, according to the design and construction and conduct of effective management. The operational phase of the project works are observed deformation and subsidence monitoring to ensure the project is functioning correctly. According to the object of study can be divided into: construction surveying, hydraulic engineering surveying, mining engineering, surveying, railroad engineering surveying, highway engineering measurement, measurement of transmission lines and pipelines, bridges, engineering surveying, tunnel surveying, tunnel surveying, military engineering survey and so on.

Ocean Mapping: The ocean water and seabed for the object, the study of marine status, determination of the marine geoid and mean sea surface, seabed and sea surface topography, marine gravity, and marine magnetic, marine environment, natural and social confidence in the geographical distribution and preparation of the various charts the theory hungry technology subjects. For ship safety of navigation, marine engineering construction protection.

Cartography: To study the maps and the preparation of the theory and methods.
