I would like to ask what is the current employment situation of doctoral students in environmental remote sensing and photogrammetry?

At present, doctoral degrees in remote sensing and photogrammetry are also difficult to obtain. For example, some institutions, although rich, do not like doctoral students, or do not want doctoral students at all. If you go to a better university or enterprise, you need doctoral students to have excellent professional knowledge, and the money you get may not be as much as that of master students who go to institutions. Many doctoral students study PhD not because they are excellent in this field, but because of employment pressure or parents' desire to study PhD. So, if you are not very good, go for a master's degree.
