Estimativa do volume de Pinus taeda L. a partir de dados de sensoriamento remoto

Abstract: O objetivo desse trabalho foi estimar o volume de madeira de um plantio de Pinus taeda L. por meio da correlação entre dados espectrais e características dendrométricas do povoamento. Para o inventário florestal, foi utilizado processo de amostragem aleatória simples com método de área fixa utilizando-se parcelas circulares de 400 m 2. A partir de imagens obtidas pelos sensores Landsat-8 e Sentinel-2, os índices de vegetação médios por parcela foram obtidos e correlacionados com o volume por parcela obtido pel… Show more

“…SAVI also showed a positive correlation in a similar work developed by Pertille et al (2019). In that research, this VI (obtained from Sentinel-2 images) had a correlation of 0.4968 with the volume of a stand of Pinus taeda L. This means that SAVI was the most sensitive vegetation index to the vegetation conditions and, therefore, it was used to estimate the volume of wood in the stand.…”

“…Orbital images of different spatial resolution have already been used to determine the volume of a stand of Pinus taeda L. in the study by Pertille et al (2019). Landsat-8/OLI and Sentinel-2/MSI data were tested, and the best estimates were made with a regression model using GNDVI, with an adjusted coefficient of determination of 0.51 and standard error of the estimate of 14.74% for Landsat-8/OLI and 0.46 and standard error of the estimate of 15.20% using SAVI obtained via Sentinel-2/MSI.…”
