Técnicas de mineração de dados para identificação de áreas com cana-de-açúcar em imagens Landsat 5

Abstract: Neste trabalho, verificou-se a aderência de técnicas de mineração de dados voltadas para problemas de classificação de dados na identificação automatizada de áreas cultivadas com cana-de-açúcar, em imagens do satélite Landsat 5/TM. Para essa verificação, foram estudadas imagens de áreas cultivadas com cana-de-açúcar em três fases fenológicas diferentes. Os pixels foram convertidos em valores de refletância de superfície, nas vizinhanças das cidades de Araras, São Carlos e Araraquara, no Estado de São Paulo. Fo… Show more

“…The automatic identification of cultivated areas is one of the most important steps in the crop forecasting process (Nonato & Oliveira, 2013). The improvement in the estimate of cultivated area of each crop directly influences the agricultural production estimates of the respective crop year (Assad et al, 2007) making decisions regarding the commodity harder to do.…”

“…Delgado et al (2012) carried out the spectral classification of sugarcane by decision tree and obtained good results. Nonato & Oliveira (2013) achieved good performances (accuracy rate of approximately 97% of the cases and a lower Kappa Index of 0.86) using DM techniques in Landsat-5 images to identify areas with sugarcane in the State of São Paulo.…”
