ResumoRemote sensing techniques and related products are an efficient and low-cost alternative of great potential for monitoring Pine crops. However, there are no conclusive studies on the magnitude of directional effects caused by variations in the geometry of data acquisition by large field-of-view satellite instruments face to the well-defined canopy architecture of Pine. This paper investigates the viewing geometry influence on the data acquisition of reflectance and vegetation indices used to monitor Pine stands. Two multitemporal series of reflectance measurements of the MOD09GA and MCD43A4 products, without and with the application of nadir normalization, respectively, were acquired and sampled according to the view zenith angle for pairs of consecutive dates with observations made in opposite directions. The influence of directional effects on the response of the Enhanced Vegetation Index, Normalized Difference Vegetation Index, and Wide Dynamic Range Vegetation Index was verified from analysis of variance (ANOVA). The results showed that the reflectance measurements were substantially influenced by the directional effects, showing lower values when calculating from the forward scattering direction, and higher values when obtained from the backscattering direction. From the three studied vegetation indices, the EVI was the most sensitive metric to directional effects. However, when calculating using normalized reflectance measurements to nadir, the directional influence on the EVI was greatly reduced when compared to the other two vegetation indices.
