"The USGS/EROS Data Center (EDC) works with USAID, the National Aeronautics and Space Administration (NASA), the National Oceanic and Atmospheric Administration (NOAA), and Chemonics International (Chemonics) to provide the data, information, and analyses needed for the FEWS NET project. NASA and NOAA collect and process satellite data that are used to monitor the vegetation condition (Normalized Difference Vegetation Index, or NDVI) and rainfall (RainFall Estimate, or RFE) across the entire African continent. The NDVI and RFE data are but two tools used by FEWS NET to monitor agricultural conditions in Africa."
