                         a large amount of remote sensing data with different temporal and 
                         spatial resolutions has increasingly made Earth observation more 
                         accessible and detailed. In this context, the use of efficient 
                         remote sensing image segmenters in remote sensing applications 
                         plays an important role in this scenario when searching for 
                         homogeneous regions in space-time domain and, consequently, 
                         reducing the dataset. In addition, multitemporal segmentation can 
                         bring a new way of interpreting data, producing contiguous regions 
                         in time. Therefore, this thesis has the objective the development 
                         of a multitemporal segmentation algorithm based on time series 
                         from remote sensing optical images. The Dynamic Time Warping 
                         distance was used as the homogeneity criterion and four case 
                         studies were performed to evaluate the proposed method. In this 
                         evaluation, time series of vegetation indices NDVI and EVI were 
                         used, generated from MODIS, Landsat-8 and Landsat- 7 images. NDVI 
                         and EVI vegetation indices from these sensors were used to create 
                         the time series. Other homogeneity criteria were evaluated. The 
                         qualitative and quantitative evaluations demonstrated the 
                         potential of the proposed segmentation method.",
