Abstract: This study seeks to evaluate the capability of data generated by the Moderate Resolution Imaging Spectroradiometer (MODIS)/Terra in discriminating phytophysiognomies found in the Amanã and Mamirauá Sustainable Development Reserves. Product MOD13, derived from MODIS data processing, comprising the Vegetation Indices EVI (Enhanced Vegetation Index) and NDVI (Normalized Difference Vegetation Index), was used to evaluate the seasonal/temporal behavior of four existing phytophysiognomies in the field between 2004 and 2005. Results showed that the vegetation indices were sensitive to the structural characteristics of the approached ecosystem and phytophysiognomies, the EVI index best discerned among the phytophysiognomies, enabling the generation of important references to work involving the dynamics of the landscape.
