基于二、三维GIS的城市动态可视化
Urban dynamic visualization based on 2D and 3D GIS
摘要
Abstract
Urban dynamic visualization plays a crucial role in urban management,planning,and decision support.However,it still faces issues such as low visualization quality and relatively low efficiency.This paper proposed a method for urban dynamic visualization based on two-dimensional(2D)and three-dimensional(3D)geographic information system(GIS)to address these problems.The integration of 2D and 3D GIS data was achieved through a data model,ensuring seamless integration of both data types.Additionally,adaptive grid division and pre-calculated occlusion removal were employed to improve the real-time and accuracy of urban spatial grid visibility determination.To ensure optimal rendering performance and quality,dynamic scheduling optimization was also applied.Experimental results demonstrate that the proposed method for urban dynamic visualization based on 2D and 3D GIS performs well,with advantages in both urban scene rendering and system computational performance.关键词
