Resumobstract: The use of images acquired by sensors at different view geometries (stereo-pairs) is consolidated considering the reconstruction of three-dimensional space by stereoscopic vision. On the other hand, the use of images acquired at different view and illumination angles is still unusual regarding the spectral information extraction, especially in Brazil. In this context, the work aims to make a spectral evaluation of a native forest fragment in northwestern Rio Grande do Sul State, in South of Brazil, using multi-angle images of the Multi-angle Imaging Spectroradiometer (MISR) sensor. The MISR sensor, onboard the Terra platform, acquires images in nine different view angles (almost simultaneously) and in four multispectral bands (blue, green, red and near infrared). The study area is the Parque Estadual do Turvo (PET), which has an area of approximately 17,500 ha. The PET is one of the largest native forest fragments of southern Brazil and has a great continuity in the province of Misiones (Argentina), extending to the Parque Nacional de Foz do Iguaçu forest Parana, Brazil. The MISR data were acquired from the Langley Atmospheric Sciences Data Center at NASA. For the evaluation, the MISR products MIL2ASLS (MISR Level 2 Land Surface Data - Bidirectional Reflectance Factor-BRF) and MIANCAGP (Anciallary Geographic Product) were used. We used the following softwares: MISR_viewer and ENVI. A total of up to 44 pixels (samples) were extracted from the PET area. To avoid spectral mixture, we defined a one kilometer buffer from the forest boundary. Bidirectional reflectance factor data (BRF) of the four MISR bands were analyzed as a function of the view direction and angle. Furthermore, we additionally analyzed the patterns of vegetation indices such as the Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI). In order to allow a comparative basis among all the bands and among the vegetation indexes, the data were normalized to nadir viewing. Results showed that the backscattering direction reflectance of all the bands was higher than in the forward scattering direction. As the view angle increased toward the backscattering direction, the reflectance value increased. The opposite pattern was observed in the forward scattering direction. When normalized to the nadir viewing, the bands of green and red showed higher anisotropy. This anisotropic pattern relates to the higher solar zenith angle in the winter combined to the litter-fall of the forest dominant species. NDVI showed higher isotropy throughout the year in all view directions, when compared to the EVI. Due to its strong correlation with the near-infrared band and the shadow fraction, the EVI showed strong anisotropy, especially in the winter. Results showed the importance of considering the spectral and angular response pattern of vegetation when biophysical (Leaf Area Index) and biochemical (chlorophyll, water content) parameters estimates are object of study using data acquired by pointing-capability or large field-of-view sensors are used.
