EXPANSÃO URBANA E SUSTENTABILIDADE: uma análise a partir das geotecnologias no município de São Lourenço – MG

Abstract

In Brazil, historically, the process of urban expansion is characterized in the majority of cases by the disorganization and intensity. The planning and management of cities according to sustainability criteria is a huge challenge, since it requires a clear vision of the urban system and the multiple interactions that take place within it. In this scenario, geotechnology can be an important instrument to obtain and analyze parameters of interest in municipal management in urban infrastructure planning and environmental preservation. The present work has as main objective to analyze the use and occupation of the soil of the urban area of the municipality of São Lourenço - MG, with the help of GIS and Google Earth PRO tools to cross sustainability indicators and evaluate the process of urban expansion. Through the software AutoCAD were produced thematic maps that compiled georeferenced data, satellite imagery of the software Google Earth PRO and qualitative data of field studies. The established maps specifically synthesized the attributes of compaction, connectivity and relation to nature. The investigation of the indicators of urban sustainability in the neighborhoods of Solar dos Lagos and Jardim das Estâncias showed the importance of establishing mechanisms for studies of land use and occupation for the correct urban planning. The study also showed that it is necessary to integrate and monitor different concepts of urban sustainability, and it is necessary to expand this study to other areas of the city.
