摘要
三维可视化可以用来描述复杂的地形情况,实现对某种地学机理的深入认识,发现常规方法所不能揭示的地形规律和特征。本文在阐述三维可视化优越性的基础上,利用ERDAS IMAGINE软件对南京地区进行三维模拟和分析,为今后从整体上研究该区域提供依据。
Three-dimensional visualization can be used to describe the situation of complex geological structure,and reach a deeper awareness of mechanism and find the laws and characteristics of the terrain which can not be revealed by conventional methods.First this paper presents the advantages of three-dimensional visualization,then using ERDAS IMAGINE software to carry out three-dimensional simulation and analysis of Nanjing,and provide a basis for research from the whole of the region in the future.
