Abstract:Urban geological work serves as a crucial foundation for urban planning and construction. It will provide geological technical support for urban planning and construction, offer a geological data baseplate for smart city construction, and presenting relevant geoscience solutions for high-quality development of cities. By using augmented reality (AR), virtual reality (VR) and GIS, the visualization of integrated three-dimensional space and geological information above and below the ground have been achieved. It will provide highly realistic, flexible, and dynamic visualization management tools for geological management in various urban scenarios, realizing panoramic roaming and interactive operation functions. Thus, it can effectively assist in urban planning and construction, underground space development and utilization, and the selection and location of major projects.
