This map illustrates satellite-detected surface waters over Dhaka, Mymensingh, Rajshahi, Rangpur and Sylhet divisions as observed from Sentinel-1 images acquired on 8 Aug 2020. Within the analyzed area of about 100,000 km2, a total of about 10,000 km2 of lands appear to be flooded. Based on Worldpop population data and the detected surface waters, about 9 million 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.
