%X The aim of this work is to estimate morphological parameters of dune systems in West African Sahel from remote sensing images that will be utilized in paleolandform studies. The sample is taken from a MSS Landsat view of the northern part of the Faguibine lake in Mali. In order to extract the very structure, sequences of morphological transformations are applied to this image and an estimation of its anisotropy is obtained by a Rose of directions method.
