VegDRI, short for Vegetation Drought Response Index, is a drought-monitoring tool developed by scientists at EROS in collaboration with the National Drought Mitigation Center and the High Plains Regional Climate Center, with sponsorship from the U.S. Department of Agriculture's Risk Management Agency. VegDRI maps, produced every two weeks, combine satellite-based observations of vegetation conditions with climate and environmental data to provide drought information for the conterminous United States.

The strength of VegDRI is its ability to integrate various drought indicators from satellite, climate, and environmental observations and identify patterns and relationships among different variables. VegDRI provides Federal and state agencies, as well as individuals, with timely and accessible local drought maps to assist in management decisions.
