This map illustrates floodwater depth inNabua and Baao Municipalities, CamarinesSur Provinces & Bato and Libon, AlbayProvince, Bicol Region (Region V) ofPhilippines based on surface watersobserved from a Sentinel-1 image acquiredon 1st of November 2020 and digitalelevation model data with the floodwaterdepth estimation tool (FwDET).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.
