摘要
遥感影像能客观地反映景物的形态、结构和空间关系等特征,使人们对地物有一个宏观整体的认识,但遥感影像所反映的二维平面不能真实地再现现实中的三维空间[1]。本文以赛利普地区为例,应用遥感图像作为纹理数据,将数字高程模型(DEM)数据与二维遥感图像叠合生成三维影像,真实再现了赛利普地区的景观特征,有效地反映该区的地形、地貌特征。
The remote sensing image can objectively reflect the characteristics of shape, structure and spatial relationship of the ground objects and enable us to get a macroscopic view of them. But the three-dimensional space cannot be reflected by two-dimensional plane. Sailipu will be taken as an example. The three- dimensional model of Sailipu is created by integrating image with Digital Elevation Model （DEM）. The model describes the topographic characteristics of Sailipu truly and effectively.
