Abstract

The creation of Normalized Difference Vegetation Index (NDVI) maps in Geographic Information Systems (GIS) can be complex and time-consuming, due to the need for various tools and processes, such as clipping and statistical calculations. To simplify this process, the Ceres plugin was developed for QGIS, which automates the acquisition of spectral images (satellite), clipping the study area, generating the NDVI map, and calculating zonal statistics. The goal is to make the production of NDVI maps more efficient and accessible for environmental monitoring and natural resource management.
