| Abstract: | With ENVI image processing software,the ETM＋ remote sensing images of Luding County,Sichuan Province which has been stitched,rectified,cut and photographic stretched,are superimposed on the Grid DEM which is generated by ANUDEM method.The virtual terrain with three-dimensional（3D） effect and the visual flight animation are built.The whole process presents the details of the specific parameter settings and the control of the 3D terrain.It provides guidance for the construction of 3D virtual scene with ENVI software. |
