Geographic information science is an undergraduate major in Chinese universities.
1. Professional definition.
Geographic information science mainly studies the basic knowledge of geography, geographic information systems, database principles, remote sensing principles and technologies, etc. It uses 3S technology to informatize the materials inside the earth system, for example, based on urban landforms. Electronic maps for mobile phone query, remote control drones, real-time positioning and navigation, etc.
2. Employment direction and postgraduate entrance examination direction.
Mining and engineering enterprises, geological exploration, photogrammetry, production management, and technology development. IT enterprises: project planning and design, project implementation and development, GIS design and development, remote sensing technology, and drones. Construction enterprises, digital city construction, urban planning and construction. Cartography and geographic information systems, surveying and mapping engineering, geography, cartography and geographic information engineering.
3. Characteristics and learning content.
Geographic data collection and processing, learn how to use modern surveying tools, remote sensing images and other geographical data sources to collect and process geographical data. This will involve technologies such as data acquisition, data cleaning, data integration and data storage. Spatial analysis and modeling, learn how to analyze and model the spatial characteristics, correlations and changing trends of geographical phenomena.
The following are some related expansion areas:
1. Geographic big data.
With the rapid development of various sensors and technologies, a large amount of geographical data is continuously generated. The major of geographical information science can be expanded into the field of geographical big data, involving large-scale data processing, storage and analysis technology, as well as the combination with artificial intelligence, machine learning and deep learning, used to solve complex geographical problems and provide intelligent decision support .
2. Regional spatial analysis.
The major of geographic information science can be expanded into the field of regional spatial analysis, and provide scientific space for urban planning, transportation planning, regional development, etc. through in-depth research on issues such as urbanization, land use, transportation networks, and population mobility. Analysis support.
