%X The Sentinel-2 mission, MSI sensor, developed under the Copernicus program by the European Space Agency - ESA, has a policy of free access, these optical satellites offer high-spatial resolution in the spectral range of 443-2190 nm, allowing the use in several Environmental applications. This study analyzed the application of the Dark Object Subtraction method - DOS, using the Semi-automatic Classification Plugin, of the QGIS software, using a scene of the sentinel-2A, visible bands (2,3 and 4) With 10 meters of spatial resolution and near infrared (5), Red Edge (6, 7, 8 and 8A), and medium infrared (11 and 12), with 20 meters of spatial resolution, having as study area the hydrographic basin Of rio Mateus Nunes, in the municipality of Paraty / RJ. It also tried to test the SNAP software Sen2Cor plug-in. Understanding the potential of Sentinel products, this work sought to understand the stage of atmospheric correction, as an essential preprocessing step for the generation of products to be used in research and mapping. Significant differences were observed in the visible bands, consistent with the literature, whereas there was no significant difference in the spectral response of the other bands in relation to the original image, in contrast, it was not possible to obtain results of the atmospheric correction using the Sen2Cor, due to conflicts in the installation of the same one in the software SNAP, being generated a supposedly corrected image identical to original.
