Use of remote sensing in soil degradation
2013
Data processing and satellite images are a useful tool for the study of land degradation. We have selected images from different sensors to analyze some cases of erosion and loss of soil quality: pollution, loss of organic matter (fire, deforestation), salinization, sealing, erosion and hydromorphic process. The sensors used for this type of study are the average spectral and spatial resolution (embarked in Landsat, Spot, Aster, EO, etc. satellites), high temporal resolution (embarked in MODIS, NOAA, etc. satellites) and radar satellites (embarked in Envisat, ERS, etc. satellites). Some areas have been selected, located in Spain, Hungary and Brazil, to study the main degradation processes.
