Rehabilitation of urban areas of precarious settlements (favelas) using GIS

In order to maximize their effectiveness, the adoption of policies for urban planning must be supported by techniques that allow the seizure and analysis of data relating to the territory where they apply these policies. The article exposes the Vila Viva program, established by the City of Belo Horizonte, Brazil, proposing to integrate slums into the urban tissue and that had their environmental studies supported intensively by GIS techniques. These techniques enabled the diagnosis of the slums and also of the environments where they are located and which the policy seeks to integrate them into. The paper compares the scenarios obtained in the original environmental study and the current reality, evaluating the results achieved in the proposed integration of slums and their effects on environmental quality.
