Wetlands are ecosystems very important for preserving water and life, since they provide diverse ecosystem services. These environments are often associated with spring areas, with particular species and other very particular characteristics. This study aimed to analyze a wetland in an urban region of Iguatemi (MS), in relation to the kind of springs and the changes caused by anthropic actions in a period from 1985 to 2017. For this purpose, watershed delimitation techniques were carried out using SRTM radar images, as well as a multitemporal analysis from the photointerpretation of the reflectance of the spectral bands. For the analysis, free images were used, as well as free software. It was possible to confirm that the springs present in the area are of the perennial type, that is, they never dry out. In addition, the multitemporal analysis allowed to identify changes in the use of the area and, consequently, in the preservation of the wetland, with changes mainly generated by the commercial planting of eucalyptus. Considering the economic, social and ecological importance of wetlands, it is suggested to conserve this area.
