             abstract = "This study aims to estimate, by using the NDVI index and the 
                         unsupervised classification method CLUSTER, the areas covered by 
                         aquatic plants in Salto Grande dam, Americana - SP, comparing 2008 
                         and 2010. The NDVI is sensitive to capture the spectral response 
                         of vegetation, which has high reflectance in the near infrared 
                         band. The classification, supervised or unsupervised, of images 
                         obtained by the index of vegetation contributes to the elaboration 
                         of thematic maps. In the process of unsupervised classification, 
                         the algorithm CLUSTER was used, which is based on a composite 
                         image, to obtain satisfactory groupings. This classifier selects 
                         the pixels at the peak of the histogram. It was observed that the 
                         area mapped with aquatic plants in 2008 is more representative due 
                         to a higher volume of them, compared to 2010. With the use of 
                         images from the satellite CBERS-2B was possible to estimate the 
                         area covered by aquatic plants on the surface of Salto Grande Dam, 
                         in Americana (SP), supported by the unsupervised classification 
                         CLUSTER, obtained after NDVI process. The maps offer an 
                         opportunity to work with a better interpreting of the different 
                         targets in the study area images, supporting the monitoring of 
                         aquatic plants in the dams and other water bodies.",
