Our research takes place within the framework of an expert system for automatic remote sensing image interpretation where we have to computer pixel's topographic context $LB@DES 89$RB@. The aim of this paper is to present a new method to locate drainage network from a digital elevation model and to compute its topographical and topological attributes. The resulting drainage network is represented by a pixel width network, such as the gray level at each network pixel represents valley's topographical attributes.
