The aim of this study was to test a method for identification of areas of severe erosion (badlands) and areas of erosion risk by means of remote sensing classification techniques. The method involved several steps : application of a supervised classification algorithm to areas with active erosion features to obtain a map of the spectral distance; selection of a classification threshold based on the ROC curve and error statistics; and assessment of the uncertainty associated with the predictions. The sudy area corresponded to the corridor of Eocene marls in the middle section of the Ésera River basin, in the central Spanish Pyrenees
