This map illustrates satellite-detected water over the flood-affected provinces of Hanoi, Red River Delta Region, Vietnam. Probable flood waters were detected with DMC multispectral data acquired on 9 November 2008 at a spatial resolution of 32m. Pre-flood DMC multispectral data from 24 November 2005 was also used in this analysis. This flood assessment is a preliminary analysis & has not yet been validated in the field.
