Use of topographic information to improve a land cover classification image-preliminary results

In this paper, we propose a scheme for a land cover classification process from satellite images, with inclusion of topographic effects (elevation) available from a digital elevation model. First, we study and analyse errors provided from the relief on an available non-topographic classification image. We then present a classification process which takes into account, for each land cover type, the non-unicity of reflectance values according to the elevation. We build a new "topographic classification", whose results and their analysis are presented
