             abstract = "The city of Alegre has an area of 772,000 kmē, being the third 
                         largest of the mesoregion of the Esp{\'{\i}}rito Santo Southern. 
                         Its urban structure has undergone great changes: the green areas 
                         have been replaced by buildings, houses, roads and other 
                         infrastructures that provide the development of the region. The 
                         objective of this work is to analyze the temporal evolution of the 
                         urbanized area of Alegre city, between the years of 1821 and 2016. 
                         The study relied on the use of maps, aerial photos and satellite 
                         images of Landsat TM 5 and Landsat OLI 8 from different epochs. 
                         The methodology was developed in three stages: Preprocessing, 
                         image information acquisition through visual interpretation and 
                         unsupervised classification using the Isoseg algorithm performed 
                         in the SPRING 5.4.1 and ArcGis 10.3 software, and, finally the 
                         spatio-temporal delimitation of the urban evolution of the area, 
                         creating polygons to calculate the urbanized area in each year of 
                         study. The results of the visual interpretation showed that there 
                         was an expansion of 191.35 ha of the urbanized area in the period 
                         from 1821 to 2016, occurring in a diffuse way, without following a 
                         preferential direction. The unsupervised classification was 
                         carried out on satellite images between 1988 and 2016, indicating 
                         an increase of 57.54 ha of urbanized area, different from that 
                         obtained through visual interpretation, which was 82.07 ha. If 
                         compared, both techniques demonstrated a growth of the urban 
                         {\'a}rea, however, the unsupervised classification method using 
                         Isoseg proved to be inaccurate.",
