Abstract
The paper brings forward a new method—3D visualization of geological interpretation of remote sensing images and image dynamical analysis for the regional geological survey, which integrates the roles of advanced technologies including “3S” (RS, GIS and GPS) techniques, remote sensing image digital processing, virtual reality and digital photographic measuration technique and so on. Based on this method, 3D virtual images are created according to certain scales and fight routes. The method commendably solves practical problems for digital regional geological survey in altiplano and makes up for some deficiency in the traditional regional geo-survey by a series of working procedures such as RS orthophoto processing, data fusion of multi-types RS images, high precision DEM building and image synthesizing.
