The super-all electronic map is now available in 150 cities across the country.

At the first China Digital Publishing Expo held this morning, an electronic map that provides remote navigation and navigation of 150 cities across 19 provinces, autonomous regions, and municipalities was officially unveiled.
According to reports, this digital map can be installed in a car, or in a mobile phone or handheld computer. In the next decade, all county-level cities and major towns in China will be covered. All map data is obtained by professional surveying and mapping units through on-site surveying and mapping. As long as the user speaks the destination, the system can use audio and map for guidance, and automatically analyze and select the best route. The electronic map error of cities such as Shanghai, Shenzhen, Wuhan, and Dalian in the satellite navigation system is no more than twice the length of the car.
