It was based on mapping of urban occupation, using a variety of cartographic sources and GIS techniques. Guarapuava city is midsize and it is located in the south-central region of Paraná State, a region that has low economic dynamics and the worst HDI (Human Development Index) in Paraná State. Data used to identification of urban occupation in different decades was analogue letters of registered urban blends, topographic maps, aerial photography and satellite imagery. Methodological procedures consisted in integration and processing of different cartographic data in a GIS (Geographic Information System).
