The Dartmouth Flood Observatory was founded in 1993 at Dartmouth College, Hanover, NH USA and moved to the University of Colorado, INSTAAR in 2010. Its sustained operation depends on grant and project support. Gift contributions are accepted. Especially if you or your organization uses these data and maps, consider helping sustain this effort.
Since late 1999, satellite data have been obtained by the Flood Observatory, processed to detect water/land boundaries, and analyzed to produce flood inundation limits in vector GIS format. DFO's Current Conditions updates this information each day into displays showing current surface water compared to the record of flooding. In 2017, we are revising the displays for global coverage. New format sample: 090E030N.

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.
This work is made possible by data acquired by NASA,
the Japanese Space Agency, and the European Space Agency, and funding support from NASA and the European Commission,
through the Global Disaster Alert and Coordination System (GDACS) project, Joint Research Centre, Ispra, Italy. The Observatory was founded in 1993 at Dartmouth College, Hanover, NH USA and moved to the University of Colorado, INSTAAR, CSDMS in 2010. The institutional support of both universities is gratefully acknowledged.
