The index created to assess grass production for the year compared to preceding years, is based on using satellite image time series.
Maps representing the percentage of green vegetation cover (fCover) are derived from the satellite imagery. This data is used to generate the Grassland Production Index (GPI) per country which represents the accumulated biomass produced daily from February 1st to October 31st of each year. The correlation between this index and real growth was scientifically established over seven years of research. A committee of scientific experts, under the auspices of the Ministry of Agriculture, also approved using this index in an insurance product.
