What contributions have high-precision maps made to the construction of a real three-dimensional China, and have they generated any valuable income?

NavInfo: Hello, our company has had applications for real-life three-dimensional road data on the vehicle side for a long time. For example, three-dimensional city data can support 3D navigation. The parts involving government and enterprise projects are mainly customized according to the needs of the owners. For example, the three-dimensional digitization of road surfaces and roadside facilities is based on high-precision maps. Thank you.
