Timesat - Phenological Cycle Analysis (DEVELOPING)

Obtaining, processing and analysis of the NDVI derived from MODIS sensor for obtaining phenological metrics of vegetation (beginning, peak and end of vegetation growth cycle, its duration and maximal productivity of the phenological cycle) of the different phytophysiognomies of the biome Cerrado (Chapada das Mesas National Park - CMNP). Processing in TIMESAT software and package rTIMESAT.
