Classificação Baseada em Objeto de Tipologias de Cobertura Vegetal em Área Úmida Integrando Imagens Ópticas e SAR

Abstract: Delinear com precisão os limites das Áreas Úmidas (AUs) e os padrões de cobertura vegetal é um passo essencial para a rápida avaliação e gestão destes ecossistemas. A Análise de Imagens Baseada em Objeto (Object-Based Image Analysis - OBIA) a partir de aprendizado de máquina e da integração de dados ópticos e de radar apresentam vantagens em relação a outras técnicas no mapeamento da cobertura vegetal nos ecossistemas de AUs. Este estudo tem como objetivo classificar tipologias de cobertura vegetal em áreas úm… Show more

“…Positive results were obtained by Belloli et al (2022) by integrating optical images and Sentinel-1 and 2A SAR, combined with OBIA and RF, to classify vegetation cover typologies in humid areas. The highest accuracies occurred in segmentations with lower similarity thresholds and with higher tree parameters and therefore more complex in RF.…”

“…45 In the vegetation cover of the experimental area, aquatic macrophytes predominate, comprising the emerging species Scirpus giganteus, with the most representative area and coverage in monodominance in the wetland. 46,47 It occurs in areas with a presence of active peat bogs, 48,49 extending for ∼1507 ha. 47 The study area is located in the geomorphological region of the Inner Coastal Plain, in a flat area with altimetry of up to 20 m. The lithology is predominantly sedimentary environments with heterogeneous peat, interconnected by floodplain deposits composed of silt-clay sand.…”
