Biome-Scale Forest Properties in Amazonia Based on Field and Satellite Observations

Liana O. Anderson
2012 Remote Sensing  
However, the opposite pattern is observed in relation to forest productivity and dynamism, which is higher in western Amazonia than in central and eastern forests.  ...  The spatial patterns on leaf phenology across Amazonia are less marked.  ...  In addition to the NDVI, the MODIS vegetation indices product also has the Enhanced Vegetation Index (EVI).  ...

2014 IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing  
Time series of MODIS (Moderate Resolution Imaging Spectroradiometer) EVI (Enhanced Vegetation Index) images are used to map land cover types based their phenological differences.  ...  The results also show that land cover phenology is closely related to the time period of flood and solar intensity for this region, similarly to what is observed in the extensive floodplain of the Amazon  ...  of seasonal flooded forest (e.g., in várzea and igapó) is dependent on the maximum level of inundation.  ...
