A literature review about the normalized difference vegetation index (NDVI) in the monitoring of degraded areas by mining projects

Abstract

Remote sensing – SR is a technique used in the study of processes on the earth's surface using sensors. One of its main applications is in the study of vegetation cover, with NDVI, thus assisting in environmental monitoring, through the education of the spatial distribution of vegetation and its probable transformations at different times. The aim of this study was to present works that used NDVI as an element of environmental monitoring in mining projects. A bibliographic review was carried out, taking into account works published between 2010 and 2018 using the following descriptors: "NDVI," "NDVI and environmental monitoring," "NDVI and the recovery of areas degraded by mining," "NDVI and its influence on mining." In all works, the importance of using NDVI was concluded, since the index provided essential data on the behavior of vegetation cover in mining processes, thus contributing to the planning and territorial management of the studied areas.
