摘要 利用ArcMap和ArcScene平台进行三维相关数据的转换和操作,首先需要构造三维地面数字模型,然后依次构造地物模型及三维效果符号,从而实现场景的三维可视化。在此基础上制作动画动态模拟生态环境演变的总体状况,就能实现基于GIS的环境演变三维动态可视化效果,直观逼真地描述公路沿线环境演变状况,最终为环境预测提供一个科学有效的可视化分析手段。 Conversion and operations of all the three-dimensional data are carried out on the ArcMap and AreScene platform in the paper. The 3D terrestrial digital model is established firstly, followed by tectonic feature modeling and 3D effects symbol to achieve the aD visualization of the scene. Then the dynamic simulation of ecological environment evolution is realized by making the three dimensional animation, which is based on 3D scene. It is intuitive and realistic description of highway environment evolution status owing to achieving the visual effect of the three-dimensional dynamic evolution with GIS technology, so as to provide a scientific and effective visual analysis tool for environmental prediction.
