Flood Water Evolution Over Town Diffa and Surrounding Areas, Niger (as of 5 Dec 2012)
This map illustrates satellite-detected probable extent of flood water evolution in the City of Diffa and surrounding areas in Niger as of 02 December, 2012. For extracting the initial flood water extent a MODIS Terra image of 11 November 2012 was used and for extracting the recent flood water extent a MODIS Aqua Image of 02 December, 2012 was used. Please note that the exact limit of the flood waters is uncertain because of the relatively low spatial resolution of the satellite sensors used for this analysis, Detected water bodies likely reflect an underestimation of all flood-affected areas within the map extent. This analysis has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.
