CERES: um plugin QGIS para automatização do cálculo do NDVI

Abstract

To producing an NDVI map using a Geographic Information System (GIS), like QGIS software, the user may encounter many difficulties in the process, such as corrected data download and adequated tools that must be used in producing the map, such as cut and NDVI raster calculators and also statistics analisis. Using these many tools applied to the development of a single map can be laborious and frustrating, especially when you have to produce and analyze months, or even years, of information. Having made these observations, the present work proposes the development of QGIS plugin software, called Ceres, which brings together all the actions necessary to produce NDVI maps and their statistical data, to pratical use from users. The process automated by the application consists of obtaining data (spectral images) from a remote sensing system, made available by the Copernicus system; automatic cut of the study area in the images; production of the NDVI map, as well as its coloring for better visual interpretation; finally calculation of the statistics of the map produced, using statistical algorithms by zones. The system aims to simplify the NDVI map production process, making it more efficient and accessible to users, providing a comprehensive solution for environmental monitoring and natural resource management through remote sensing.
