This map illustrates the satellite-detected surface waters in Barbuda Island (Antigua and Barbuda) as observed from the Radarsat-2 image acquired on 11 September 2017, following the landfall of tropical cyclone IRMA-17 on 06 September 2017. Within the analyzed area, the increase of surface waters is about 34%. It is likely that flood waters have been systematically underestimated along highly vegetated areas and within built-up urban areas because of the special characteristics of the used satellite data. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR - UNOSAT.
