Characterization of the state of soil degradation by erosion using the hue and coloration indices

This study focused on the characterization of the state of soil degradation by erosion using the hue and coloration indices and on the integration of the SWIR. The results obtained show that the hue and the coloration indices using ETM5 and ETM7 channels of Landsat-7 allow for a better discrimination of the different states of soil degradation. The integration of these indices with the NDVI and a priori knowledge of the study area within an unsupervised classification allowed an excellent characterization of degraded soils and those subject to degradation.
