DFO is using automated MODIS-based data from the NASA Global Flood processor to monitor the flooding in NE India, July 15, 2017. Red shows current surface water; blue is typical winter conditions; light gray is all previously mapped flooding. Click on dots to retrieve microwave observation of changing river discharge.

Sentinal 1 SAR mapping of flooding in China, July 3, 2017 (red is new water compared to May 28, 2017). Mapping is in progress
(WMS: http://bit.ly/2smWx1G; all mapping is now online; final geocoding/correction will occur July 10)
Surface Water Watch and Record
In 2017, updating of all sheets is underway; 030E020N illustrates the new format
Since late 1999, satellite data have been obtained by the Dartmouth Flood Observatory, processed to detect water/land boundaries, and analyzed to produce flood inundation limits in vector GIS format. Surface Water Watch and Record compiles this information to produce a comprehensive record of terrestrial surface water variability, past and present. Daily updating of selected map sheets is now underway. This effort has been sustained through support from NASA, the European Commission, the World Bank, the Latin American Development Bank and others. In 2017, we are completing revision of all online map sheets to a new format. Each map sheet provides a record of past changes and also present water extent.
The Global Flood Partnership is a network of organizations that are developing an operational global flood observational and risk modelling infrastructure: for better predicting, monitoring and measuring large flood events and their impacts, worldwide.
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.
