1. Geodesy and Survey Engineering

Entering the 21st Century, surveying and mapping technology has transited from the traditional analog era to the digital era, and is now entering the information era. Modern geodesy and surveying engineering, characterized by the combination of space positioning technology, computer technology, modern communication technology and traditional ground surveying technology, is undergoing profound changes. Geodesy and Surveying Engineering is developing from the traditional one-dimensional or two-dimensional, small scale, low precision and static measurement, to three-dimensional or four-dimensional, large scale, high precision and dynamic measurement. All these have made the subject more widely and deeply infiltrated into people’s daily life and various fields, such as city information platform, urban regional planning and dynamic monitoring, intelligent traffic management system, environmental changes and monitoring, natural disaster monitoring and defense, national public security emergency information platform, public emergency prevention and rapid response, marine ecological and environmental protection, agricultural accurate operation and informatization, etc..

3. Cartography and Geographic Information Engineering

Through space information collection, intelligent abstraction, storage, analysis, visualization, management and application, Cartography and Geographic Information Engineering is a subject using map graphics language and mathematical model language to describe the spatial distribution, interrelationship and dynamic evolution characteristics of various natural, humanistic and social phenomena in nature and human society. With the rapid development of information technology, knowledge engineering and computer technology, Cartography and Geographic Information Engineering has become an important tool for human beings to recognize the geographical environment, utilize geographical resources, promote the sustainable development of society, and support digital earth science research. As a comprehensive interdiscipline and technology formed by a combination of surveying and mapping science and geographical science, computer science, information science, intelligence and cognitive science, and many other subjects, Cartography and Geographic Information Engineering is the basis of the formation and development of earth information science and it has extensive application prospect in the national economy departments (such as agriculture and forestry, mining, metallurgy, water conservancy, transportation, environment, marine, navigation, administrative management, municipal administration, urban planning and management, national defense construction, operation command, etc.) and has greatly promoted the scientific and technological progress and development of related disciplines. The geographic information systems established for various departments have brought enormous social and economic benefits.
