Report Content:

Virtual geographic environments refer to digital representations of real-world geographic environments. Digital twins, through the mapping and bidirectional interaction between the real and virtual worlds, replicate the attributes, structures, states, performances, and behaviors of physical entities in the virtual world, creating high-fidelity virtual geographic environments. These environments are key to the interconnection of humans, machines, and objects, and have become essential tools for new-generation scientific experimentation and analysis. They offer new means for understanding, controlling, and interacting with the physical world. This report will primarily introduce the achievements in enhanced visualization of digital twin scenes in geographic environments, including key technologies such as rapid geographic scene perception and fusion modeling, geographic process simulation, and multi-level enhanced visualization. These techniques have been applied in major engineering projects.
