Generally speaking, this is a promising new industry. As the earth is closely related to human life, its changes will have a great impact on us, whether it is man-made or natural. Geographic information system provides us with technical methods to monitor, extract and analyze such problems. As a subject closely related to computer, it has a bright future. As the tertiary industry, it received strong support from the state during the Twelfth Five-Year Plan period. As a new industry, it will provide many opportunities to produce new technologies.

Personally, it is very important to choose a school for this major. If the school is good, you will have more practical opportunities. If the school is not good, you don't even know what you are studying. At present, there are several good ones: the GIS major of the School of Remote Sensing of Wuhan University is mainly photogrammetry and remote sensing, the School of Resources and Environment is mainly cartography and GIS engineering, and the key laboratory is mainly based on 3S; Tongji university's GIS is mainly surveying and mapping; The GIS of Peking University focuses on engineering projects; The geographic information system of Beijing Normal University focuses on remote sensing application and quantitative remote sensing. The School of Geographical Sciences and Planning of Sun Yat-sen University pays attention to the application of urban planning.

I hope it helps you ~ ~
