The Flood Observatory facilitates use of space-based information for international flood detection, flood response, future risk assessment, and hydrological research. In 2013-2017, it is leading a NASA Applied Sciences project to assist World Food Program use of flood mapping information. Click on video below for visualization of WFP logistics.
