Digital image processing techniques are applied to a multispectral data set (Landsat 5-TM) in order to map Quaternary morpho-sedimentary units showing the geomorphological evolution during Quaternary times in the Huércal-Overa basin (SE Spain). The obtained result is compared with a conventional map of the area considered as ground-truth by means of GIS overlay operations. The final result shows a general quantitative poor accuracy related to the total areas representing the mapping units, especially if compared with the accuracy analysis procedures provided by the digital image processing software. Nevertheless, most of the mapping units boundaries can be distinguished, allowing a relatively good differentiation of the morphosedimentary units through remote sensing techniques.
