Construction of digital twin scenic spot empowerment system

[Project Background]

In response to the "14th Five-Year Plan" digitalization strategy for cultural tourism, a 5A-level scenic spot has joined hands with Meixiang Information to create a "full-factor, full-cycle, full-scene" smart scenic spot hub. The project relies on the digital twin engine to achieve two-way mapping and real-time interaction between physical space and digital space.
