This map illustrates satellite-detected waterextent as of 07 January 2018 overToamasina districts, Atsinanana Region, inMadagascar as detected by Sentinel-1.Some standing water areas could beobserved north and south of Toamasina,mainly in the agricultural and/or open areasalong the river. It is likely that floodwatershave been systematically underestimatedalong highly vegetated areas along mainriver banks and within built-up urban areasbecause of the special characteristics of thesatellite data used. This is a preliminaryanalysis and has not yet been validated inthe field. Please send ground feedback toUNITAR UNOSAT.
