Title
Satellite detected water extents in Bac Giang and Hai Duong Provinces, Viet Nam as of 10 September 2024
Description
**UNOSAT code: TC20240905VNM, GDACS ID: 1001090** This map illustrates the aggregated floods using Sentinel-1 images acquired on 10 September 2024 at 17:58 local time using an automated analysis with a machine learning method. Within the analysed area of about 3,000 km², a total of about 50 km² of land appears to be affected by flood waters. Based on Worldpop spatial demographic data, about 33,000 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.
