Abstract

This article presents research findings on the development process of monitoring land degradation changes based on applying satellite images, GIS and the multi-criteria evaluation method MCE-AHP-GDM (Multi-criteria Evaluation-Analytic Hierarchy Process-Group Decision-Making). The map of the current state of land degradation in the two periods was established from investigation data, sample analysis data, topographical data, meteorological data, etc., and data extracted from VNRedSat-1 satellite images. (serves to create maps of soil eroded by rain.)
