Análise espacial de vazios urbanos na zona norte da cidade de Teresina

Abstract

Urban voids are a reality in large cities, persisting for long periods even in planned areas. Despite existing guidelines for land use and occupation, these voids persist, resulting in high urbanization costs. Real estate speculation often arouses interest in the financial potential of these voids. This research aims to identify, classify and quantify urban voids with infrastructure in the northern area of the city of Teresina, using technologies such as Geoprocessing and Remote Sensing. Through the analysis of these data, the location of urban voids was mapped and suggestions for the use of these spaces were offered, as well as identifying areas available for occupation within the existing infrastructure in the municipality. This is an analytical, descriptive and exploratory research that employs qualitative and quantitative approaches. To achieve the proposed objectives, several procedures were used, such as bibliographic review, survey and analysis of georeferenced data using QGIS software, analysis of satellite images and preparation of thematic maps. The result of this research is a detailed diagnosis, containing precise information on the location, extent, quantity and characteristics of the identified urban voids. This information will be essential for strategic planning and for proposing the occupation of these spaces, taking into account the potential of each area studied. In addition, this research contributes to the understanding of the problems related to urban voids and their specific causes in the urban territory. Through the analysis of the data obtained through geoprocessing, it will be possible to identify the factors that contributed to the existence of these voids, such as the expansion of the urban perimeter, real estate speculation and the housing deficit.
