Ifanadiana MODIS EVI

This dataset contains Enhanced Vegetation Index (EVI) values from MODIS images, extracted directly at fokontany level. Data are available from 2000 to the present day, with an original spatial resolution of 250m and a temporal resolution of 16 days, updated at a frequency of 16 days. The processed data represents a monthly mean aggregated to the level of the fokontany using the spatial mean.

Columns :
- comm_fkt : name of fokontany using standardized ‘new_commune’_’fokontany’ nomenclature
- vill_evi_modis : evi values calculated from Modis images
- date : month in format YYYY-MM-DD
