Opis

Soil sealing in large urban centers and their effects on the environment and society is increasingly present in cities. This study aims to analyze the soil sealing process of Feira de Santana due to urban expansion. This Bahian municipality is the second largest population in the state, which was recently elevated to the rank of a regional metropolis and it has a relatively flat topography. Over the years, this area has lacked in studies that would guide urban planning, promote environmental education and implement urban sanitation. The collection of satellite images of the urban area of the city and vectors were utilized to delimit the neighborhoods, and thus an urban boundary was created. From this, georeferencing, segmentation and classification of images and a statistical analysis of data through spatial analysis were achieved in this study. Modeling and image processing were performed with GIS SPRING software. The results sought out to depict the areas most affected by soil sealing and others that are in the sealing process due to urban growth, which classified the types and occurrence of intensity and the presence of "green" or water bodies.
