The present work aimed to analyze the main types of soil and the Normalized Difference Vegetation Index (NDVI) of the municipality of Poranga-CE for the years 2014, 2016, 2018 and 2020, using remote sensing techniques as a form of subsidy. for the knowledge, use and conservation of the soils present in the area. So that we could analyze the soils and vegetation, it was necessary to develop soil maps, slope and NDVI through Landsat8 satellite images, OLI sensor, Digital Elevation Models and Shapefiles. The maps creation processes were carried out within two GIS environments, Qgis version 3.16 and Global Mapper. Average annual rainfall data from 2014 to 2020 were also collected to help analyze the behavior of vegetation in the NDVI results, since it is a region with a climate and vegetation characteristic of the semiarid region. . The maps and rainfall data allowed us to analyze and reach the conclusion that the main soils that occur in the study area belong to the classes of NEOSSOLOS QUARTZARÊNICOS, NEOSSOLOS LITÓLICOS, LATOSSOLOS AMARELOS, ARGISSOLOS VERMELHOS and PLANOSSOLOS HÁPLICOS with a predominance of Plano, Suave Ondulado and Ondulado reliefs, and that the vegetation cover of the municipality has increased due to the increasing levels of precipitation since 2014.
