UN Operational Satellite Applications Programme (UNOSAT)**UNOSAT code: TC20201013VNM** This map illustrates satellite-detected surface waters in Thua Thien Hue Province of Viet Nam as observed from a Sentinel-1 image acquired on 25 October 2020. Within the analyzed area of about 4,000 km2, a total of about 230 km2 of lands appear to be flooded. The water extent appears to have a static level since 22 October 2020. Based on Worldpop population data and the detected surface waters, about 50,000 people are potentially exposed or living close to flooded areas. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR-UNOSAT. Important Note: Flood analysis from radar images may underestimate the presence of standing waters in built-up areas and densely vegetated areas due to backscattering properties of the radar signal.satellite-detected-waters-in-thua-thien-hue-province-of-viet-nam-as-of-25-october-2020Humanitarian Data ExchangePublicSatellite detected waters in Thua Thien Hue Province of Viet Nam as of 25 October 2020DatasetsViet Nam2020-10-26
