Use of Remote-Sensing to the Study of Landuse Change in the Lower-Cheliff Plain (Algeria)

The remote sensing application and land-use mapping are among the current challenges. The lower Chellif plain was the subject of our study. It is located at 220 km far from the west of Algiers, and has suffered from serious problems of its environment degradation, climate aridity. In addition to the salinization of soils which accelerated over the last two decades.This work constitutes a contribution in the study of land use changes using remote sensing combined with field data and soil salinity, The supervised classifications of the two satellite images allowed the determination and the follow-up of different land use classes. The changes were obtained by comparing two obtained classifications maps of the Landsat images between the two periods of summer 2006 and summer 2014 in terms of surface area and spectral behavior.
