In recent years, activities related to socio-economic development have led to land cover (LC) changes in the upper part of the Dong Nai river basin. The use of remote sensing applications to analyse the impacts of these changes plays an important role in the managing the sustainability of theriver basin. This paper introduces a solution for analysi...
