I know that apart from general non-geographical majors such as Google Earth and Maps, the geographical professional software that can be used to learn geography is mainly map processing, such as SuperMap, Map GIS, ENVI, Arc GIS and so on. The first one is the software developed by domestic SuperMap company, and the genuine one is more expensive. You can apply for a trial version and download the application license. The period seems to be three months. The second operation and interface are relatively simple. Functions can be spatial analysis, path analysis and simple graphics processing, as well as rendering of three-dimensional views. You don't need to apply for permission, just download and install the software directly. The third is mainly aimed at map correction, classification, adding geographical coordinates, cutting, vegetation analysis, band calculation and so on. You don't need to apply for a license to install the software, but many versions are in English. If necessary, you can install Chinese patches. The last one is said to be more powerful than the previous ones. It is learning, and it has higher requirements for computer systems. It has more powerful and accurate map image processing function. Authentic ones are more expensive. You can apply for a trial version, and there are installation tutorials online.
That's all I know so far. I didn't pretend to use anything else. I hope the information is helpful to you.
