“…The difference between the two zones of eucalyptus developed eucalyptus and eucalyptus in development, happens FCUP Remote sensing and GIS combination to evaluate the ecosystems' conditions in "Serras do Porto" because the NDVI presented higher values in zones with major densification and vegetative vigor. The here-obtained values of NDVI were slightly lower than the values obtained in previously published studies in zones with high presence of eucalyptus (Boratto & Gomide, 2013;Santos et al, 2015;Sartori et al, 2009). A possible explanation of the values obtained in this work is that the area used to be a forestry exploitation with i industrial aims.…”

“…The highest average value was 0.357 for the year 2016. Santos et al (2015), analyzing the parameters NDVI and SAVI in an irrigated area located near the city of Paranapanema -SP, found for the SAVI the mean values of 0.48 (01/30/2014) and 0,338 (09/09/2014), respectively.…”

“…Sendo o valor de 0,25 para regiões de vegetação densa; 0,5 para vegetação com densidades intermediárias ou superfícies heterogêneas e 1 para vegetações de baixa densidade. Em geral o valor de 0.5 é comumente utilizado para o fator L, mas deve-se levar em consideração o padrão de vegetação da região, que para esse fator corresponde a densidades intermediárias (Huete, 1988;Allen et al, 2002;Rêgo et al, 2012;Santos et al, 2015). Após o cálculo do SAVI realizou-se a classificação da região proposto por Cerqueira & Santos (2017) conforme a Tabela 2.…”
