城市三维景观构建是数字城市建设的一个关键.在阐述数字摄影测量方法构建三维景观优越性的基础上,利用ERDAS IMAGINE遥感图像处理软件的强大功能完成城市区域三维景观的构建,生成虚拟现实世界,为城市三维景观的建设提供了新的方法.
The construction of urban 3D landscape is one of the key factors in construction of digital city. Based on the advantages of photogrammetry in building 3D landscape ,the paper expounds meth- od of constructing urban 3D landscape and creating virtual reality by using ERDAS IMAGINE, a powerful software of remote sensing image manipulation. These provides a new method for the con- struction of digital city.
