Aerial photography can be used to collect terrain data, which can be imported into digital twin technology. Through digital twin technology, highly realistic three-dimensional models can be constructed. These models can not only accurately reflect the topography and building layout of the actual environment, but also simulate the impact of different planning schemes on urban space. This helps planners to intuitively foresee and evaluate planning effects in the early stages of design, thereby improving the accuracy and effectiveness of planning.
