USGS FEWS NET Data Portal
The USGS FEWS NET Data Portal provides access to geo-spatial data, satellite image products, and derived data products in support of FEWS NET drought monitoring efforts throughout the world. This portal is provided by the USGS FEWS NET Project, part of the Early Warning Focus Area at the USGS Earth Resources Observation and Science (EROS) Center.

FEWS NET Software Tools
Interactive map viewers allow users to visualize administrative and crop zone time series of normalized difference vegetation index, dekadal (10-day) rainfall, and seasonal cumulative rainfall, including options for data download.
The Early Warning eXplorer (EWX) software is an interactive web-based mapping tool that allows users to visualize continental-scale rainfall estimate (RFE), land surface temperature (LST) and total precipitable water (TPW) data and anomalies at varied time steps and review time series analyses.
The water point map viewer, which monitors 234 water points from Mali to Somalia, will help a range of government and non-government actors understand the current availability of water for livestock and human consumption. This will inform food security analysis, humanitarian assistance planning, an...
DSM (Drought Status Monitor) is an experimental decision support tool based on weather and crop conditions. It incorporates drought monitoring rules that distinguish severity and provide a generalized drought indicator at national and sub-national scales.
The GeoWRSI is a geo-spatial, stand-alone implementation of the Water Requirements Satisfaction Index (GeoWRSI), as it is implemented by the USGS for the FEWSNET Activity. The program runs a crop-specific water balance model for a selected region in the world, using raster data inputs. The program ...
The Geospatial Stream Flow Model (GeoSFM) provides a common visual environment for monitoring wide-area hydrologic events. The model can be run operationally to identify and map the status of stream flow and soil water conditions.
