                         expans{\~a}o da cidade de Altamira entre os anos de 2000 e 2010 
                         foi avaliada com base na integra{\c{c}}{\~a}o de dados de

                         caracterizar as transforma{\c{c}}{\~o}es dos bairros, indicando 
                         que a expans{\~a}o urbana associou-se ao crescimento de 40\% de 
                         {\'a}reas de solo ou impermeabilizadas em detrimento de 
                         {\'a}reas de vegeta{\c{c}}{\~a}o. A integra{\c{c}}{\~a}o de

                         The city of Altamira (PA) underwent major territorial changes 
                         starting in the 1970s, with the acceleration of the agricultural 
                         frontier expansion in the Brazilian Amazon. New forms of urban 
                         occupation were juxtaposed to urban structures inherited from 
                         previous periods at the same time as the city area expanded. 
                         During the 1970s, urban population grew at a rate of 16\% per 
                         year. In subsequent decades, the growth rate decreased, reaching 
                         an average of 3\% per year between 2000 and 2010. In recent 
                         years, the construction of the Belo Monte hydroelectric power 
                         plant can be associated with new transformations in the city. In 
                         this study, urban expansion in Altamira between 2000 and 2010 is 
                         analyzed based on the integration of data from different sources, 
                         including TM imagery, orthophotos and field data. A methodology 
                         was developed for land cover classification of 2000 and 2010 
                         images of TM sensor, using Linear Spectral Mixture Model and 
                         Vegetation-Impervious surface-Soil Model (V-I-S) techniques. 
                         Triaxial diagrams of V-I-S model were used to characterize change 
                         at the district level, showing that urban expansion in the period 
                         of study was associated with a 40\% increase in areas of soil or 
                         imperviousness at the expense of vegetation cover. Data 
                         integration was performed for the identification and analysis of 
                         city structure and expansion. It was inferred that the urban 
                         structure included one central district and one additional center 
                         sheltering popular commerce and services, along with specific 
                         settlement for industrial plants and high-income housing; urban 
                         expansion took place mostly along regional roads and access 
                         corridors, as the main center appeared to expand itself towards 
                         the city southwest sector. Urban occupation along Amb{\'e}, 
                         Altamira, and Panelas creeks were subjected to flooding after Belo 
                         Monte plant construction and resulted in the creation of new 
                         neighborhoods for displaced dwellers, while new parks are planned 
                         to be created in those areas.",
