This map illustrates satellite detected flood water over the affected State of Assam, India. Those areas likely covered with flood water as of 2-5 August 2007 are shown in red and are distinguished from pre-flood water levels (in blue) as measured for 1-10 May 2007. This is a preliminary analysis and has not yet been validated in the field.
