Uso do sensoriamento remoto para determinação do índice de áreas verdes do bairro centro, no município de Mocajuba – Pará

Abstract

Green area conceptualized as a place where there is a predominance of arboreal vegetation, and in this sense, afforestation plays an important role in the quality of life in the urban environment, as it provides a pleasant natural environment. In order to study and quantify the green areas of the central neighborhood of the city of Mocajuba - PA, a study was carried out based on orbital images from the CBERS4A satellite and knowledge of geographic information systems (GIS). After producing a map of land use and occupation for the area of interest, the Green Area Index (IAV) was calculated to demonstrate the amount of square meters of public and private green area per inhabitant in this neighborhood. From the generation of this map it was also possible to calculate another index, the Urban Vegetal Coverage Index (ICVAU) in addition to the Green Index per Inhabitant (IVH). It is noted that the green area of neighborhood Center is below the ideal, obtaining a low IAV. The neighborhood's vegetation cover index was also below ideal. The IVH was above the ideal, demonstrating that there are a lot of trees but not enough in the public space.
