CONSTRUCTION OF THIRD DIMENSION SKETCH-UP OF KALYAN-DOMBIVLI, MUMBAI DISTRICT, INDIA USING GIS TECHNIQUE

Three D-modeling has been the privilege of architects and engineers. But, the usage of 3-D
modeling is no longer limited to design and engineering details. It is being used by urban planners in
decision making and visual representation. The usage of 3-D model is primarily for the purpose of visual
analysis like shadow analysis, line-of sight, building density, etc. The rapid urbanization process is
brining such indicators a new importance, where the city is not only expanding horizontally but vertically
too

三维建模（3-D modeling）曾是建筑师与工程师的专属技术手段。但如今，三维建模的应用范畴已不再局限于设计与工程细节，城市规划师也已将其应用于决策制定与可视化呈现工作中。三维模型的核心应用方向为视觉分析，涵盖阴影分析、视域分析、建筑密度测算等场景。快速城市化进程为这类指标赋予了全新的重要性——当前城市不仅在平面维度向外拓展，同时也在垂直维度向上延伸。
