NASA Near Real Time Experimental Flood Maps

100W050N

Automated mapping of surface water changes using the LANCE MODIS rapid response processor.

Updated Daily. See also the Surface Water Record

MODIS data (four scenes, Terra and Aqua, over two days) are used to classify water pixels using an algorithm developed at the Dartmouth Flood Observatory. Use of four images (two sequential days) for each daily update allows most cloud shadow noise to be removed, and decreases obscuration from changing cloud cover. Data are processed at NASA Goddard Space Flight Center, and transmitted to the Flood Observatory for display.
