Paper Abstract

The aim of this study is to present a method for improving the geological interpretation of remotely sensed data in areas which are never entirely free of cloud cover (temperate or tropical climatic zones). The method is based on the production of ortho-images and pseudo- stereoscopic pairs by means of a digital elevation model (DEM). The interpretation is done under a mirror-stereoscope on geometrically corrected images. The images could be interpreted in terms of geomorphology (volcanoes, drainage patterns, etc.), petrography (volcanic differentiates), and structure (faults, annular anomalies). By using stereoscopy it is possible, on a TM 4 5 2 color-composite to distinguish three-dimensional geological features using their spectral responses. These features are not clearly visible without stereoscopy. ERS 1 radar stereoscopy improves the hierarchization of the lineament pattern. The combination of backscattering and stereoscopic view emphasizes geological structures characterized essentially by their texture.
