Resumo: | The maintenance of riparian forests is considered one of the main vegetative practices for mitigating the degradation of water resources and is mandatory by law. However, in Brazil there is still a progressive and constant decharacterization of these areas. Facing this reality, it is necessary to broaden researches that identify the occurring changes and provide efficient solutions at a fast pace and low cost. Remote sensing techniques show great application potential in characterizing natural resources. The objective of this work was to map, to characterize the land use and occupation and to verify the best method of high spatial resolution image classification of the Permanent Preservation Areas of the Funil Hydroelectric Power Plant reservoir, located between the municipalities of Lavras, Perdões, Bom Sucesso, Ibituruna, Ijací and Itumirim, in the state of Minas Gerais. The methods used to classify the high spatial resolution image from the Quickbird satellite were visual, object-oriented and pixel-by-pixel. Results showed the best method for mapping land use and occupation of the study area was object-oriented classification using the K-nearest neighbor algorithm, with kappa coefficient of 0.88 and global accuracy of 91.40%. |

Contudo, no Brasil, ainda há uma progressiva e constante descaracterização dessas áreas. Diante de tal realidade, torna-se necessário ampliar pesquisas que identifiquem as mudanças ocorridas e forneçam soluções eficientes com rapidez e baixo custo. Técnicas de sensoriamento remoto demonstram grande potencial de aplicação na caracterização dos recursos naturais. O objetivo deste trabalho foi mapear, caracterizar o uso e a ocupação do solo e verificar o melhor método de classificação de imagem de alta resolução espacial das Áreas de Preservação Permanente do reservatório da Usina Hidrelétrica de Funil, localizada entre os municípios de Lavras, Perdões, Bom Sucesso, Ibituruna, Ijaci e Itumirim no Estado de Minas Gerais. Os métodos utilizados para classificação da imagem de alta resolução espacial do Satélite Quickbird foram: visual, orientada a objetos e pixel a pixel. Os resultados demonstraram que o melhor método para o mapeamento de uso e ocupação do solo da área de estudo foi a classificação orientada a objetos, utilizando o algoritmo K-nearest neighbor, com coeficiente kappa de 0,88 e exatidão global de 91,40%.Instituto Federal de Educação, Ciência e Tecnologia do Sul de Minas Gerais - IFSULDEMINAS2020-05-13T17:39:57Z2020-05-13T17:39:57Z2019-09info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfapplication/pdfSOARES, J.
