China Daiwa University of Mining and Technology, which is better, a graduate student majoring in photogrammetry, remote sensing and GIS?

These two are similar, judging from the current domestic industry development. . . The 3S field is on the rise. . . GIS will be relatively easy, and photogrammetry and satellite remote sensing are the main forces of domestic measurement technology at present. The future development of science and technology must be more and more satellites NB, but the photogrammetry technology is still constantly updated. I'm sure I can achieve higher accuracy. . At least, if you learn photogrammetry, you don't have to worry about losing your job in your life. It depends on whether you are a boy or a girl. Now you graduated from GIS, majoring in software development.
