This map illustrates satellite-detected water extent as of 07 January 2018 over Brickaville distric, Atsinanana region, in Madagascar as detected by Sentinel-1. As of 07 January 2018, ~ 2600 ha of land over Brickaville commune seem to be inundated and 2400 in Andovoranto commune. These zones are mainly agricultural and/or swamps. These waters seem to be the results of the recent heavy rain related also to the cyclone AVA-18 which made landfall the 05 January 2018. It is likely that flood waters have been systematically underestimated along highly vegetated areas along main river banks and within built-up urban areas because of the special characteristics of the satellite data used. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR UNOSAT
