APLICAÇÃO DO NDVI NA AVALIAÇÃO DA APA DO RIBEIRÃO ARARAS, MUNICÍPIO DE PARANAVAÍ, PR, BRASIL

Abstract

Water resources are essential for the development of human life and economic activities, and for their use water needs to be of good quality. In the municipality of Paranavaí, in the northwest of the state of Paraná, to guarantee the quality of water distributed to the population, the Environmental Protection Area (APA) of the Araras stream was created. In this sense, the present work aims to evaluate vegetation in the APA area, justified by the need to monitor the area. The assessment was carried out through the analysis of satellite images, using Digital Image Processing (PDI) techniques, using the Normalized Difference Vegetation Index (NDVI). The results obtained indicate that the vegetation in the studied area did not present variations related to vegetation suppression, with only variations in vegetation density being recorded, which may be related to variations in rainfall rates.
