| Summary: | The accelerated process of urban development in Brazil sometimes generates so- cial and environmental vulnerability through spontaneous settlements, which are inhabited by low-income populations. Informal settlements are physical manifesta- tions of urban poverty and intra-urban inequality. This generalization in underde- veloped countries is related to the process of “poverty urbanization”. Remote sens- ing provides a spatial view of the city and the temporal processes that impact the environment and degrade the quality of urban life. This kind of information is es- sential for providinge base-line information for urban decision makers. The present work aims to establish a methodology based on object-oriented analysis, applied to high spatial resolution satellite images (QuickBird) in order to characterize informal settlements. The introduction includes a theoretical discussion on urbanization and informal settlements. The study was conducted in the Ipês neighborhood in the João Pessoa district of the Paraiba State, Brazil. The total area classified as substandard settlements was 29,342 m2, which represents 1.6% of the total area of this neigh- borhood. The methodology proved to be effective in identifying irregular areas, and is an important tool for cadastral information updating and urban planning. |
