There are many kinds of geographical atlases, such as Huanggang Geographic Filled Atlas and Beidou Geographic Atlas. There is not much difference between them. As long as the icon is not mislabeled, there is no big problem. Beidou geographical atlas is better, which I used in high school. I'm from Shandong. Although the examination questions in different provinces are different, the key points are the same. Atlas is universal, so don't think too much about regional issues. In addition, I suggest that you'd better remember the map in the textbook, don't let go of every detail, and then write it down in the reference book. After all, exams are based on textbooks.

Beidou map road guidance is intuitive and convenient, and the voice prompts are clear and clear. It supports road signs and actual road prompts of main and auxiliary roads, island roads and expressways, and can cope with complex road conditions calmly. In terms of positioning and navigation accuracy that everyone is most concerned about, Beidou map can be within 1 meter at present, accurate to specific lanes. At the same time, Beidou map will provide more accurate location services for future unmanned driving. Beidou Qixing (Chongqing) Internet of Things Technology Co., Ltd., a subsidiary of Beidou Technology Group, has developed the world's first Internet of Things module based on Beidou communication technology, which can provide location services to the centimeter level. It can be said that it is very awesome!
