Powerpoint record of this display
GIS data for this display are located at: http://floodobservatory.colorado.edu/GISdata/. See http://rapidfire.sci.gsfc.nasa.gov/subsets/ for geographic location of the MODIS 250 m 721 image subsets used to create the surface water extent files. The GISdata directory is organized to match these subsets. MODIS data are from NASA/GSFC, MODIS Rapid Response. See this link for brief technical description of our water mapping procedure.
