基于Cesium的城市内涝模拟三维可视化方法

Study on Urban Waterlogging Simulation and Visualization Method Based on Cesium

针对城市内涝研究中存在的问题,通过分析水文模型数据中的关系模式及结构特征,研究水文模型与三维可视化结合的集成方法,探索城市内涝演化过程及机理与三维可视化的结合.基于SWMM模型,利用开源的Java Script地图引擎Cesium,将内涝模拟结果展示在三维场景中,设计实现了模拟参数可调的城市内涝三维可交互式可视化系统.

This paper attempts to analyze the relationship patterns and structural features in hydrological model data,study the interactive method of hydrological model and 3D visualization,and explore the method of combining waterlogging evolutionary processes and mechanisms with 3D visualization.This paper uses the open source JavaScript map engine Cesium to display the waterlogging simulation results in a 3D scene based on SWMM,and implements a three-dimensional interactive visualization system for urban waterlogging with adjustable simulation parameters.
