The phenological metrics could be extracted from the time series MODIS NDVI datasets with the help of TIMESAT software by using algorithms like Savitzky-Golay, asymmetric Gaussians and double logistic.

Hi,

Another good toolbox is SPIRITS

Thank you for sharing your knowledge

Cédric Aurelien Nguimdo Matsaguim Thank you. Will this software work on ArcGIS?

Hi Kiran

SPIRITS doesn't work directly with arcgis. It's very usefull for time series analysis. However you can use it to preprocess your modis data, then export your results in a format compatible with arcgis.

That's how i integrate these two softwares
