Abstract

The topographic effect and radiation effect are two key elements which affect the accuracy of classification of the remote sensing image. Topographical normalization is a valuable tool by use of DEM. Because the time when the image is acquired differs from that of DEM, a new error was induced in the procedure of topographical normalization. It is obvious that the image classification and DEM accuracies can be improved by use of the same spatial temporal and spatial resolution image and DEM. The DEM help radiation correction, on the other hand, the image provide some information on Earth objects to restore DEM. A new system was developed, which can provide highly accurate DEM and remote sensing image synchronously
