UN Operational Satellite Applications Programme (UNOSAT)**UNOSAT code: TC20240905VNM, GDACS ID: 1001090** This map illustrates the aggregated floods using Sentinel-1 images acquired on 13 September 2024 at 05:58 local time. Within the analysed area of about 38,000 km², a total of about 1,300 km² of land appears to be affected by flood waters. Based on Worldpop spatial demographic data, about 900,000 people are 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 the United Nations Satellite Centre (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 the backscattering properties of the radar signal.satellite-detected-water-extents-in-red-river-delta-viet-nam-as-of-13-september-2024Humanitarian Data ExchangePublicSatellite detected water extents in Red River Delta, Viet Nam as of 13 September 2024DatasetsViet Nam2024-09-13
