                         network from the SAREX project RADAR image using Mathematical 
                         Morphology tools. The problem is to find a mapping from a grey 
                         level image into a binary image that exhibits the drainage. The 
                         selected region is from a test site in Acre, SW Amazonia, Brazil. 
                         In RADAR images, the drainage network appears with high contrast 
                         and well defined shape. Mathematical Morphology is a theory for 
                         spatial structure analysis and aims here at analyzing the shape 
                         and the forms of the drainage network. This analysis is based on 
                         the set and lattice theories. This paper uses the MMach, a 
                         Mathematical Morphology Toolbox for the KHOROS system.",
