The intense urbanization of the city of São Paulo took a rapid and disorderly way. As a result of this process, there was an increase of occupancy of flood plains, channeling streams and soil sealing, causing several changes in urban microclimate, including the occurrence of heat islands, thermal anomalies and changes in precipitation. In the case of precipitation, in recent decades, it has intensified the occurrence of heavy rains causing flooding and flooding, especially in the downtown area. Thus, this study aims to present the analyzes, resulting from the urbanization process, resulting in a high degree of vulnerability of Subprefecture Sé, jeopardizing the quality of life for residents. The overall objective was to evaluate, through the use of geotecnology, use and occupation of land and vulnerability to flooding in central urban areas. For this, we used the analysis of use and ococupation of land by satellite images of IKONOS and QuickBird and mapping of risk areas. Extreme weather events, with changing patterns of precipitation, heat waves and prolonged drought cause serious problems for the people, especially those most vulnerable and needy. With the results of analyzes were generated thematic maps and graphics, which can contribute to propose strategies to support public policies
