Flood Observatory Mission Statement
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 your organization uses these data and maps, consider helping sustain this effort

Mapping of Hurricane Maria
(Below, satellite synthetic aperture radar mapping of Hurricane Maria-induced flooding, September 21, 2017, north shore of Puerto Rico, from Copernicus/European Space Agency data. Red is new water compared to a pre-flood image.)

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 compiles this information in near real time to produce a comprehensive record of terrestrial surface water variability, present and past. In 2017, we are revising the processing algorithms and displays. Draft new format samples: 030E020N, 090E030N, 100W040N
Mapping of Hurricane Irma
Below: flood mapping for the Irma storm, September 10-16, using a combination of Copernicus/European Space Agency Sentinel 1 (processed by Drs. Son Nghiem, JPL, and Robert Brakenridge, DFO) and NASA MODIS (from NASA LANCE and Goddard Spaceflight Center).
