| 摘 要： | 本文着重介绍了基于数码城市GIS的几种常用日照分析实现方法及特点，包括实现动态的3维阴影，对不同地区，不同季节的各种复杂建筑物单点进行日照时间计算。基于数码城市GIS进行日照环境分析，在3维场景中再现一天内日照阴影的变化，比2维中日照阴影分析更全面、生动、直观。由于建筑物的位置和高度以及屋顶的形状是真实的，因此计算出的日照时间等数据准确、可靠。可以为城建规划审批部门、处理日照纠纷部门、规划设计师及居民提供快捷可靠的科学分析手段和准确的日照数据。

| Abstract: | The paper introduces the realization and the characteristics of some common sunlight analysis methods base on CyberCity GIS, including 3D dynamic shadow and the sunlight time's calculation of every kind of single point complex building at different districts in different seasons. Compared with 2D sunlight analysis, imitating certain day's shadow changes in 3D scene is more lively and more visualized. For the building's real position, height and roof's shape, the calculating result is more precise and reliable. It can provide a quick and certain scientific analyzing method and accurate data for urban plan departments, urban plan designers and citizens. |
