The specialty of geographic information science was formerly the specialty of geographic information system, which was put forward by goodrich in 1992. Compared with geographic information system, it pays more attention to geographic information as a science, not just a technical realization, and mainly studies a series of basic problems raised in the process of processing, storing, extracting, managing and analyzing geographic information with computer technology.
Di Xin is the abbreviation of geographic information science. Geographic information science is an undergraduate major in Chinese universities.
1, Introduction to the Scientific Meaning of Geographic Information
Geographic information science is a four-year undergraduate major in Chinese universities. After graduation, the bachelor of science degree will be awarded.
This major mainly studies the basic knowledge of geography, geographic information system, database principle, remote sensing principle and technology. Using 3S (GPS, GIS, RS) technology, the materials in the earth system will be informationized, such as making electronic maps according to urban landforms for mobile phone inquiry, remote control of unmanned aerial vehicles, real-time positioning and navigation, etc.
2. What does geographic information science study?
The courses of geographic information science study include photogrammetry, GIS spatial analysis, GIS design and development, introduction to remote sensing, physical geography, metrological geography, remote sensing digital image processing, satellite navigation and positioning principle and application. The professional direction of some colleges and universities is: digital city construction, smart city construction, drone remote sensing.
3. The employment prospect and direction of geographic information science.
With the process of informatization in various departments of the country and the increase and development of high-tech enterprises engaged in the development of geographic information system engineering in China, the demand for this professional talent will increase and the gap will expand.
After graduation, students majoring in this major can engage in geological exploration, photogrammetry, production management, technology development, project planning and design, project implementation and development, GIS design and development, remote sensing technology, unmanned aerial vehicle and other work in mineral, engineering, IT and construction enterprises.
