Which is better, Wuhan University remote sensing science and technology specialty or Surveying and Mapping?

Remote sensing science and technology specialty of Wuhan University introduced.

Remote sensing science and technology is a new frontier subject developed on the basis of the cross-infiltration and mutual integration of space science, electronic science, earth science and computer science. It uses non-contact sensors to obtain the time and space information of the target. Because it involves a wide range of scientific and technological fields, its application has been deeply involved in economic construction, social development, national security and people's lives. To provide scientific basis and military intelligence services for major national decision-making and national defense construction, graduates have great social demand and broad employment prospects, and can engage in the production, design, planning and management of photogrammetry, remote sensing and surveying and mapping, and work in relevant teaching and scientific research units. Graduates' adaptive positions include remote sensing, surveying and mapping industry, information industry, aerospace, urban planning, earthquake monitoring, petroleum, electric power, geophysical exploration and other energy fields, with wide employment levels and high employment quality.

Remote sensing science and technology specialty mainly faces the needs of national spatial information infrastructure construction, and cultivates compound senior technical application talents who master the basic theories, methods and technologies of remote sensing science and have professional knowledge of spatial information acquisition, processing, analysis and application. Students in this major mainly study basic theories and knowledge such as remote sensing principle, photogrammetry, geographic information system, computer science and technology, digital image processing, etc. Master the theory and technical methods of image information acquisition and processing, target recognition and 3D reconstruction, and geographic information management and application, so that students can apply their majors to solve practical problems such as spatial information analysis, expression and application. In addition, students of this major should also engage in comprehensive practice and practice of surveying course, basic course design of photogrammetry, course design of remote sensing principle and application, comprehensive practice of GIS principle course, course design of GPS measurement and data processing, comprehensive practice of digital image processing course, database design, comprehensive practice of microwave remote sensing course, practice of remote sensing application model, and practice of network GIS program design.

The above words may make people feel obscure. In fact, remote sensing technology is around us. Meteorological cloud pictures of changing weather forecast, surveillance and shooting of spy satellites in European and American blockbusters, dam site selection and road route selection in engineering geological investigation, geological prediction in earthquake disasters, hydrological and geomorphological identification in water conservancy projects, etc. Both of them include remote sensing science and technology, which has been listed as a strategic goal of priority development in many developed countries. In China, remote sensing science and technology have also been widely used, providing information and technical support for national decision-making, resource investigation, environmental protection, disaster monitoring, major projects and national defense construction.

Domestic universities offering remote sensing science and technology specialty include Wuhan University, Shandong University of Science and Technology, Southwest Jiaotong University, Chang 'an University, Nanjing University of Information Science & Technology, Beihang University, Harbin Institute of Technology, Chengdu University of Information Engineering, PLA Information Engineering University, Henan Polytechnic University, Air Force University of Aeronautics and Astronautics, China Geo University, Xuzhou Normal University, Nanjing Institute of Meteorology, etc. Among them, Wuhan University is one of the schools with an earlier history and a larger student scale. Remote sensing science and technology specialty has a strong faculty and advanced teaching and research facilities. Academician Wang, the founder of the discipline, is the first aerial survey expert in China to receive a doctorate. He put forward the goal of "focusing on the needs of national economic construction and tracking the forefront of world scientific development" for the development of this discipline. Academician Li Deren, the academic leader, still holds the highest score in the doctoral thesis of Stuttgart University. He pioneered the iterative method of selecting weights from posterior variance estimation to locate gross errors, which was called "Li Deren method" by the international surveying community; He put forward an extended reliability theory based on two multidimensional alternative assumptions of error discoverability and resolvability to deal with measurement errors, which scientifically "solved the unsolved problems in surveying for a century". Today, the whole world is using Li Deren's theory to correct its own aerial survey adjustment system. Academician Zhang Zuxun, an academic leader, has achieved world-class research results in the automation of aerial (sky) mapping, and won a series of awards from countries and ministries such as the National Natural Science Award and the National Science and Technology Progress Award. He launched VirtuoZo, a digital photogrammetry system with independent intellectual property rights in Australia, which produced economic benefits exceeding 1 100 million yuan. The school has also established MODIS remote sensing satellite receiving station, all-digital photogrammetry laboratory, geographic information system (GIS) laboratory, remote sensing (RS) data comprehensive processing laboratory, digital watershed research center and other teaching facilities and scientific research institutions.
