The present map shows flood affected areas visible from a Radarsat-2 image (01/09/2012)and ancillary COSMO-SkyMed image (31/08/2012). Flooded areas have been derived bysemi-automatic image processing techniques.Basic topographic features such as transportation, hydrology and settlements in the area ofNiamey (NIGER) are derived from public datasets, refined by mean of visual interpretation ofpre-event satellite images RapidEye © RapidEye (acquired on 23/10/2010, 24/11/2010 and26/12/2010, GSD 6.5 m, <5% cloud coverage).All satellite images have been radiometrically enhanced and georeferenced.The estimated geometric accuracy of this product is 20 m CE90 or better, from nativepositional accuracy of the background satellite image.The estimated thematic accuracy of this product is 85% or better, as it is based on previousexperience in using high-resolution SAR for flood extend deliniation. Please be aware thatthe thematic accuracy might be lower in urban and forest areas due to known limitations ofthe analysis technique.Map produced on 02/09/2012 by GAF under contract 257219 with the EuropeanCommission.
