摘要
提出了综合利用二维矢量数据、航空影像和激光测距与距离修正数据建立三维城市模型的技术路线,并在此基础上探索了城市噪音污染信息在现有三维城市模型中的建模和可视化方法。
This paper took out a technique route that set up 3D City Model using 2D vector data, aerial photography and laser detection and ranging. On the based ofthese, the paper explored the methods for building and visualizing urban noise pollution in existing 3D City Model.
