Within the analyzed area of about 5,000 km2, a total of about 200 km2 of lands appear to be flooded. The water extent appears to have increased of about 50 km2 since 4 November 2020. Based on Worldpop population data and the detected surface waters, about 65,000 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. 1000734 TC20201028VNM UNOSAT@UNITAR.ORG (UNOSAT) TC https://unosat-maps.web.cern.ch/unosat-maps/VN/TC20201028VNM/UNOSAT_A3_Natural_Landscape_TC20201028VNM_ThuaThienHue_VietNam_10112020.jpg http://unitar.org/unosat/node/44/3174 15.96 107.01 16.83 107.01 16.83 108.14 15.96 108.14 15.96 107.01 16.83 107.01 unosat
