Is there a good prospect for GIS specialty?

Whether the professional prospect is good or not depends not only on whether you have worked hard, but also on the social demand for GIS.

But, most importantly, you must understand. Even while the iron is hot, you still have to get hard. If this major has a good employment prospect, but your grades are not good, others will not want you!

Therefore, if you choose this major and study hard, no one can say what will happen in the future. Learn first, and it is most important to have a skill.
